ABSTRACT:
A multiprocessor system (100) for sharing memory has a memory (102), and two or more processors (104). The processors are programmed to establish (202) memory buffer pools between the processors, and for each memory buffer pool, establish (204) an array of buffer pointers that point to corresponding memory buffers. The processors are further programmed to, for each array of buffer pointers, establish (206) a consumption pointer for the processor owning the memory buffer pool, and a release pointer for another processor sharing said memory buffer pool, each pointer initially pointing to a predetermined location of the array, and adjust (208-236) the consumption and release pointers according to buffers consumed and released.
