 The X_ID, Y_ID and L_ID are coded on NX, NY, NL bits respectively.
 The NX, NY and NL parameters are global for a given instance of the TSAR architecture.  NX & NY cannot be larger than 5 (no more than 1024 clusters),
-but can be smaller, if the number of clusters is larger than 1024. NL is equal to 4 (no more than 16 target ports or 16 initiator ports per cluster).

+In order to simplify the hardware implementation of the memory coherence protocol, the L_ID values are standardized on the coherence network, and the same value is used for an initaitor port and for a target port: If the number of processors per cluster is NPROCS, the processor L_ID value is between 0 and (NPROCS-1).  The memory cache L_ID is equal to NPROCS.
