 *  modifications/bugs
 *   - Split the primitive IDs into 3 sets, so that future primitives can
 *     be placed in the appropriate section (common/slave/master) without
 *     affecting the already existing primitive lists on the host machines.
 *     Currently primitives must be added to the end of the entire list to
 *     avoid ID changes of existing primitives & thus re-writes of the
 *     primitive lists. Updated the example.                         10.04.02 dpsf
 *   - Moved rodConfiguration #defines to rodConfiguration.h, where
 *     they belong.                                                  11.04.02 dpsf

 *************************************************************************************
 *
 * Primitive lists sent from one CPU to another and reply lists returned from the
 * recipient CPU have a 3 parts:
 *      list header:  tagged by the structure MSG_LIST_HEAD declared in msgBuff.h
 *      list body:    composed of the list of primitive or reply messages
 *      list trailer: tagged by the structure MSG_LIST_TAIL declared in msgBuff.h
 *
 * The primitive and reply messages in the list body have 2 parts:
 *      message header: tagged by the structure MSG_HEAD declared in msgBuff.h
 *      message body:   (optional) primitive specific data.  If there is primitive
 *                     specific data, there should be a structure tag for it defined
 *                     in primParams.h (this file).  There should be separate tags for
 *                     input and/or output data as needed.
 *
 * The primitive functions themselves never see the listHeader, listBody or msgHeader.
 * These structures are interpreted by the interface routines, readListWrapper() and
 * execPrim() in listManager.c.  Because of this, changes in the common structures do
 * not require changes to any of the primitive functions, only to one or the other of
 * the interface routines.  This reduces effort but more importantly reduces the
 * possibility of errors.
 *
 * On receipt of a new primitive list, readListWrapper() extracts the information from
 * the list header and the list trailer and checks it for errors.  This information
 * guides the execution of the list.
 *
 * execPrim() is called once for each primitive in a primitive list.  execPrim()
 * extracts the information from the message header, checks it for errors and branches
 * to the appropriate primitive function.  Primitive functions are all of type INT32
 * and have a single argument, a pointer to a structure of type PRIM_DATA declared in
 * primFuncts.h.  execPrim() fills the PRIM_DATA structure before branching to the
 * primitive function.
 *
 * All primitive functions receive a pointer to struct PRIM_DATA as an argument.
 * There will be many authors of primitives, so it is important that the use of this
 * structure is clear.  The structure is described in detail here, followed by
 * instructions of how to add a primitive, with an example.
 *
 *************************************************************************************
 *                          The PRIM_DATA data structure
 *************************************************************************************
 *
 * PRIM_DATA is a 5 element structure which is passed to each primitive function. It
 * is the sole argument passed to the primitive functions and is filled for all
 * primitives by the function execPrim() in listManager.c.  It's use by a primitive
 * function may be tricky so requires care!  In particular, 2 of the elements in
 * PRIM_DATA are themselves pointers to structures defined by the author of each
 * primitive.  These are priBodyPtr and repBodyPtr which point to data used by the
 * primitive and returned from the primitive, respectively.  The structures tags which
 * describe this data are defined by the primitive authors in this file (primParams.h).
 * The elements of PRIM_DATA are now described:
 *
 * UINT32 *priBodyPtr - This is a pointer to the (optional) message body.  As
 * described above, the message body contains primitive specific data which should be
 * described by a structure whose tag is in this file (primParams.h).  The executable
 * on the CPU which sent the primitive list is also built with primParams.h and so
 * uses the same structures to build the primitives.  This ensures that the data
 * described by the structure in primParams.h is what the primitive function receives.
 *
 * UINT32 priBodyLength - This is the number of 4 byte words in the primitive body.
 * This may not always be the same for a given primitive if, for example, one of the
 * primitive data structure elements is of variable length, as in the example below.
 *
 * UINT32 *repBodyPtr - This is a pointer to the (optional) message body of the reply
 * data.  If there is reply data from the primitive, this pointer tells the primitive
 * function where it should put that data.  Again, the author of the primitive is
 * responsible to define a structure tag to describe this data.  That tag should also
 * be in this file (primParams.h).
 *
 * UINT32 repBodyLength - This is the number of 4 byte words in the reply message body.
 * It should NOT include the reply message header, tagged by MSG_HEAD, which is added
 * by execPrim() and which the primitive function knows nothing about.  execPrim()
 * initializes repBodyLength to 0; the primitive function does not need to set it to 0
 * if there is no reply data.
 *
 * UINT32 *repBuffEnd - This points to the last valid address where a primitive can
 * write reply data.  The primitive function can use this to check that the bounds of
 * the reply buffer are not exceeded.  The error code MSG_EXCEEDS_LIST_BOUND can be
 * returned if the reply message has been truncated.  The interface routine, execPrim(),
 * also checks that a primitive has not not exceeded the boundaries of the reply buffer.
 *
 * The interface routines do not look at the input data, they just pass a pointer to
 * the data. So just as the primitive routines are not affected by changes in the
 * common structures, the interface routines are not affected by changes to primitive
 * functions and the associated data structures.  This division means that only people
 * familiar with a particular piece of code ever have to edit it, and it limits the
 * amount of code which is affected by changes.  This all reduces the likelihood of
 * introducing bugs when making such changes.
 *
 *************************************************************************************
 *          readListWrapper(), execPrim() and CPU to CPU consistency checks
 *************************************************************************************
 *
 * Each primitive has up to five items defined in this header file:
 *
 *      ID                            (required)
 *      revision number               (required)
 *      structure tag for input data  (required if there is input data)
 *      structure tag for output data (required if there is reply data)
 *      legal values of parameters    (recommended if there are illegal values)
 *
 * Primitive functions are called from the interface function, execPrim(), based on
 * the primitive ID, which is an element of the MSG_HEAD structure.  The executables
 * on both the sending and receiving CPUs are built with this header file.  The CPU
 * which builds and sends the primitive loads ID into MSG_HEAD to communicate which
 * primitives are to be executed.  The CPU which receives the primitive list extracts
 * ID from MSG_HEAD and branches to a primitive functions based on ID.
 *
 * The branching is done by execPrim().  Within execPrim() the primitive ID is used
 * as an index of an array of structures which has one array element per primitive.
 * The structure tag, PRIM_PARAMETERS, is defined in primFuncts.h.  It has 2 elements:
 *
 * struct PRIM_PARAMETERS {
 *    INT32 (*primFunction)(struct PRIM_DATA *);
 *    INT32 primRevision;
 * };
 *
 * primFunction is a pointer to the primitive function.  primRevision is the current
 * revision of the primitive.  This is needed to ensure the executables of the sending
 * and receiving CPUs were built with the same version.
 *
 * Because primitive IDs index an array of pointers to primitive functions, they
 * must be sequential.  Defining the IDs according to the model below, e.g.
 *
 * #define ECHO              0
 * #define MEMORY_TEST       (1 + (ECHO))
 * #define SET_ERRMSG_MASK   (1 + (MEMORY_TEST))
 *
 * etc. ensures that the primitive IDs are sequential.
 *
 * Note: The primitive IDs have been divided into 3 sets: common to both master & slave
 * DSPs, slave only, master only. New primitives belonging to a given set should be
 * placed at the end of the set, so that the previously written primitive lists
 * stored on the host computers still remain valid. They are still ordered sequentially
 * within the sets to simplify the listManager code. (Table lookups in execPrim,
 * checkPrimHeader and initializePrimParams translate the IDs into indices).
 *
 * The revision number is intended to ensure that both CPUs, sender and receiver,
 * are using the same version of a primitive.  In particular, there could be problems
 * if the definition of the input data structure or the output data structure is not
 * the same on both CPUs.  The primitive revision is an element, primRevision, of the
 * MSG_HEAD structure which is filled by the sending CPU.  The receiving CPU checks
 * the transmitted version of primRevision in the message header with its local copy
 * in the PRIM_PARAMETERS structure and aborts with an error message if there is a
 * mismatch. This check is performed in a single place, in the interface routine
 * execPrim() in listManager.c.  It should NOT be performed by the primitive
 * functions.  In fact, execPrim() does not pass the revision number to the primitive.
 *
 * There are no restrictions on the mnemonic constants which are used to define the
 * ID, the revision and the structure tags for the input and output data of the
 * primitive functions.  However, because these constants will be used not only by the
 * author of the primitive but also by the authors of code which builds primitive
 * lists, there should be some consistency in how they are defined.  The following
 * model has been used so far:
 *    The ID should indicate what the primitive does.
 *    The revision should be the ID preceded by R_ and should be of the form xxyy
 *   where xx is the major revision number and yy is the minor revision number.
 *    The input structure tag should be the ID appended with _IN
 *    The output structure tag should be the ID appended with _OUT.
 * For example say we have primitive which sorts the input data and returns this as
 * output data and that this primitive follows a primitive with ID ECHO in the list.
 * We would have:
 * #define SORT_DATA    (1 + (ECHO))            ID is mnemonic and sequential
 * #define R_SORT_DATA           300            revision number 3.00
 *    struct SORT_DATA_IN {                     structure tag for input data
 *      char *unsorted;
 *    };
 *    struct SORT_DATA_OUT {                    structure tag for output data
 *      char *sorted;
 *    };
 *
 * In some cases, it may also be useful to define mnemonics for legal values of
 * parameters which are passed in the structures.  See, e.g., SET_LED below.
 *
 * Finally, the constant PRIM_LIST_REVISION, below, is intended to ensure that the
 * primitives which are defined on both CPUs are the same and in the same order, i.e.
 * a given ID number corresponds to the same primitive on both sides.
 * PRIM_LIST_REVISION should be incremented in the following situations:
 *
 * 1) A primitive is added to this file.
 * 2) A primitive is removed from this file.
 * 3) The primitives in this file are reordered.
 * *) It does NOT need to be incremented in the event that individual primitives are
 *    revised. PRIM_REVISION takes care of that.
 *
 * The primitive list and the reply list have a common header structure which is tagged
 * by MSG_LIST_HEAD in msgBuff.h.  This structure has an element, primListRevision,
 * which the sending CPU fills with its copy of PRIM_LIST_REVISION.  The receiving CPU
 * checks this against its copy of PRIM_LIST_REVISION and aborts if there is a
 * mismatch.  This check is performed in a single place, in the interface routine
 * readListWrapper() in listManager.c.

 *
 * Note that the last line of code which assigns repBodyLength may take other forms.
 * For example the echo primitive (in primFuncts.c) has in the body an arbitrary
 * number of data words given by priBodyLength and pointed to by priBodyPtr both
 * members of the PRIM_DATA structure.  The return message will have the same number
 * of words in its body and they will be placed at repBodyPtr, also a member of the
 * PRIM_DATA structure.  So there we do not have a structure indicating where the
 * primitive and reply data are or their sizes.  repBodyLength is assigned by the line
 *   primData->repBodyLength = primData->priBodyLength.
 * Other examples of this type of exception are in the rwFifo() in masterPrimFuncts.c
 * and in the sortData example below.
 *
 * Note also that in noReturnDataSkel, it was not necessary to set repBodyLength to
 * 0.  This is done in the interface routine, execPrim(), from which all primitives
 * are called.

 *************************************************************************************
 *                                  EXAMPLES
 *                   How to add a primitive in 5 easy steps.
 *************************************************************************************
 *
 * Here, the procedure to add a primitive function, checkBit(), is described.
 * checkBit() checks whether a bit in a register is set. The result is returned in a
 * reply message. checkBit is a primitive common to both types of DSPs, so it is
 * placed at the end of the common section.
 *
 *  1) In primParams.h, define the constant mnemonic for the primitive ID, the
 *     revision number and structure tags for the input and output (reply) data.
 *
 *    #define CHECK_BIT (1 + (<previously last primitive>))
 *    #define R_CHECK_BIT   100
 *       struct CHECK_BIT_IN {
 *         UINT32 registerId;
 *         UINT32 bitNumber;
 *       };
 *       struct CHECK_BIT_OUT {
 *         UINT32 bitSet;
 *       };
 *
 *    #define LAST_COMMON_PRIMITIVE         (CHECK_BIT)
 *
 *  2) In primParams.h, near the bottom, add the prototype for the primitive function.
 *
 *    INT32 checkBit(struct PRIM_DATA *);
 *
 *  3) In primParams.h increment PRIM_LIST_REVISION.
 *
 *  4) Update primIDList & the primParameters array inside initializePrimParams in
 *     primFuncts.c; add in the new primitive in the appropriate spot (bottom
 *     of common, slave-only, or master-only functions):
 *
 *     primIDList[++primLoop]=                  CHECK_BIT;
 *     primParameters[primLoop].primFunction=   checkBit;
 *     primParameters[primLoop].primRevision=   R_CHECK_BIT;
 *
 *  5) In primFuncts.c, slavePrimFuncts.c or masterPrimFuncts.c, write the routine...
 *
 *    INT32 checkBit(struct PRIM_DATA *primData) {
 *
 *      INT32 returnCode = SUCCESS;
 *      INT32 error;
 *      UINT32 registerId;
 *      UINT32 bitNumber;
 *      UINT32 bitSet;
 *
 *      struct CHECK_BIT_IN *checkBitIn =
 *                        (struct CHECK_BIT_IN *)primData->priBodyPtr;
 *      struct CHECK_BIT_OUT *checkBitOut =
 *                        (struct CHECK_BIT_OUT *)primData->repBodyPtr;
 *
 *      registerId = checkBitIn->registerId;
 *      bitNumber = checkBitIn->bitNumber;
 *
 *      error = readRegister( registerId, 1, bitNumber, &bitSet);
 *
 *      if (error < 0) {
 *        addError(&returnCode,error, "checkBit","readRegister", __FILE__, __LINE__);
 *        if (FATAL(returnCode)) { return returnCode; }
 *      }
 *
 *      checkBitOut->bitSet = bitSet;
 *      primData->repBodyLength = SIZEOF(struct CHECK_BIT_OUT);
 *
 *      return returnCode;
 *    }
 *
 *  (Note how an error return from a function call is handled.)
 *
 * Now we add a primitive function, sortData(), just after checkBit(). sortData sorts
 * input byte data and returns the sorted list. Like checkBit, sortData has both input
 * and output data. However, neither the input nor the output data has an associated
 * structure.  They are after all just unstructured data lists of unspecified length.
 *
 *  1) In primParams.h, define the constant mnemonic for the primitive ID and the
 *    revision number. In this case there are no structure tags.
 *
 *    #define SORT_DATA (1 + (CHECK_BIT))
 *    #define R_SORT_DATA   100
 *
 *    #define LAST_COMMON_PRIMITIVE         (SORT_DATA)
 *
 *  2) In primParams.h, near the bottom, add the prototype for the primitive function.
 *
 *    INT32 sortData(struct PRIM_DATA *);
 *
 *  3) In primParams.h increment PRIM_LIST_REVISION.
 *
 *  4) Update primIDList & the primParameters array inside initializePrimParams:
 *
 *     primIDList[++primLoop]=                  SORT_DATA;
 *     primParameters[primLoop].primFunction=   sortData;
 *     primParameters[primLoop].primRevision=   R_SORT_DATA;
 *
 *  5) In primFuncts.c, slavePrimFuncts.c or masterPrimFuncts.c, write the routine...
 *
 *    INT32 sortData(struct PRIM_DATA *primData) {
 *
 *      INT32 returnCode = SUCCESS;
 *      char *inPtr, *outPtr;
 *      char tmp;
 *      UINT32 numElements, outer, inner;
 *
 *      inPtr  = primData->priBodyPtr;
 *      outPtr  = primData->repBodyPtr;
 *      numElements = 4 * primData->priBodyLength;
 *
 *      if ((UINT32)inPtr + numElements > (UINT32)primData->repBuffEnd) {
 *        newError(&returnCode, MSG_EXCEEDS_LIST_BOUND, FATAL_ERR, "sortData",
 *                 "reply data will exceed reply buffer boundary...aborting",
 *                 __FILE__, __LINE__);
 *        return returnCode;
 *      }
 *
 *      for (outer = 0; outer < (numElements - 2); ++outer) {
 *        for (inner = 0; inner < (numElements - 2 - outer); ++inner) {
 *          if ( *(inPtr + (char *)inner) > *(inPtr + (char *)(inner+1))) {
 *            tmp = *(inPtr + (char *)inner);
 *            *(inPtr + (char *)inner) = *(inPtr + (char *)(inner+1));
 *            *(inPtr + (char *)(inner+1)) = tmp;
 *          }
 *        }
 *        *(outPtr + (char *)(numElements-1-outer)) =
 *                      *(inPtr + (char *)(numElements-1-outer));
 *      }
 *      *outPtr = *inPtr;
 *
 *      primData->repBodyLength = primData->priBodyLength;
 *
 *      return returnCode;
 *    }
 *
 * Note that here a check has been added to make sure the reply data does not exceed
 * the reply data buffer.
