发明名称 Apparatus for sharing memory in a multiprocessor system
摘要 A computer system shares memory between multiple processors by dividing the memory into a plurality of sections, subsections, and banks, and by providing a memory path between each processor and each section of memory. Each processor may generate references to the memory from any one of four ports, which are multiplexed to the memory paths and onto the sections of memory. The system provides that each processor has an associated register in each subsection of memory and that each processor can make no more than one reference to a subsection at a time. Reference conflict resolution means are provided at the processor level to arbitrate conflicts between ports in the processors attempting to reference the same section or subsection in the memory. Reference conflict resolution means are provided at the subsection level of the memory to arbitrate conflicts between different processors attempting to reference the same banks of memory.
