IPC: G06F12/08
Filed: 2001-07-12
Abstract: PROBLEM TO BE SOLVED: To efficiently maintain data consistency in thread parallel processing in a multi-processor system constituted of a plurality of processors. SOLUTION: Processors #0 to #3 execute in parallel a plurality of threads in which execution order relation is regulated. When a processor #1 to execute a certain thread updates the present cache memory #1, when pieces of data with the same address exist in a cache memory #2 of a processor #2 to execute a slave thread, they are simultaneously updated. However, even when the pieces of data exist in a cache memory #0 of a processor #0 to execute a master thread, they are not rewritten and a fact that rewrite is performed is recorded. When the thread is completed by the processor #0, a cache line in which a fact that the rewrite from the slave thread is performed has a probability to invalidated and a cache line without record is invalidated. For a cache line having probability to be invalidated, whether it is actually invalid is checked during execution of the next thread.
