Multiprocessor Space
The multiprocessing space maps the internal memory space of each Tiger-
SHARC processor in the cluster into any other TigerSHARC processor.
This allows one processor to easily write to and read from other processors
in a multiprocessor system. Broadcast space allows write access to all Tig-
erSHARC processors in the cluster. Each TigerSHARC processor in the
cluster is identified by its ID. Valid processor ID values are 0 through 7.
