US Patent 7328314 Multiprocessor computing device having shared program memory

An instruction memory shared by a number of processing units has a plurality of individually accessible sections. A software program in the instruction memory is distributed among the memory sections. Sequential parts of the software program are in sequential sections. The software program may have a common portion which is repeated in each of the memory sections. Arbiter logic may control which of the processing units accesses which of the memory sections in each memory access cycle.
