Method and apparatus for developing multiprocessor cache control protocols using a memory management system generating atomic probe commands and system data control response commands
A memory management system couples processors to each other and to a main memory. Each processor may have one or more associated caches local to that processor. A system port of the memory management system receives a request from a source processor of the processors to access a block of data from the main memory. A memory manager of the memory management system then converts the request into a probe command having a data movement part identifying a condition for movement of the block out of a cache of a target processor and a next coherence state part indicating a next state of the block in the cache of the target processor.
