Abstract
A multiprocessor system includes a plurality of data processors. Each data processor includes: a data processing core; a memory forming a local portion of a unified memory; and a global memory arbitration logic. Each local portion of the unified memory is dual ported. The global memory arbitration logic arbitrates access to a first port among the corresponding data processing core and a close data processing core. The global memory arbitration logic arbitrates access to a second port of another data processor among data processing cores having a far connection to that local portion of unified memory. The dual port memory is preferably time multiplexed. The global memory arbitration logic grants a local peripheral bus priority access to both ports of the local portion of unified memory.
