Abstract
A multi-processor system includes a global bus ( ) having associated therewith a global address space with a plurality of processor nodes ( ) associated therewith. Each of the processor nodes ( ) has a CPU ( ) associated therewith which interfaces with a local bus. The local bus has a local address space associated therewith. A dual port SRAM (DPSRAM)( ) is provided for interfacing between the global bus ( ) and the local bus ( ). Each DPSRAM ( ) for each processor core ( ) has a defined address space within the global bus address space. Whenever any of the global resource writes to the particular processor node ( ), it is only necessary to address the designated DPSRAM ( ) and transfer data thereto. The act of transferring the data thereto will generate an interrupt to the associated CPU ( ) which will then cause it to read the received data on the local bus by addressing its associated DPSRAM ( ). This results in only a single access cycle for transfer of the block of data from the global resources to the designated CPU ( ).
