    摘要: In a memory access controller (202), a classifying unit (302) classifies a CPU (#0) to CPU (#3) into a first group of CPUs having made an exclusive access request to a shared memory (201) and a group of CPUs not having an exclusive access request. Subsequently, in the memory access controller (202), a detecting unit (303) detects a CPU having completed exclusive access among the first group of CPUs, and a notifying unit (304) sends to a core standing by for exclusive access among the first group of CPUs, a notification of release from a state of standby.
