An error controlling system includes a plurality of error generation target circuits, a plurality of pseudo error generating devices each having a pseudo error content holding register that holds directed pseudo error content, each plurality of pseudo error generating device generates a pseudo error corresponding to a pseudo error content held in a respective pseudo error content holding register in at least one of data to be written to one of the plurality of error generation target circuits and data to be read from one of the plurality of error generation target circuits upon being directed to generate the pseudo error, and a pseudo error controlling device that directs the plurality of pseudo error generating devices to generate a pseudo error corresponding to a respective pseudo error content held in each of the pseudo error content holding register provided in each of the plurality of pseudo error generating devices.
摘要:
A cache memory having a sector function, operating in accordance with a set associative system, and performing a cache operation to replace data in a cache block in the cache way corresponding to a replacement cache way determined upon an occurrence of a cache miss comprises: storing sector ID information in association with each of the cache ways in the cache block specified by a memory access request; determining, upon the occurrence of the cache miss, replacement way candidates, in accordance with sector ID information attached to the memory access request and the stored sector ID information; selecting and outputting a replacement way from the replacement way candidates; and updating the stored sector ID information in association with each of the cache ways in the cache block specified by the memory access request, to the sector ID information attached to the memory access request.
摘要:
A cache memory unit connecting to a main memory system having a cache memory area in which, if memory data that the main memory system has is registered therewith, the registered memory data is accessed by a memory access instruction that accesses the main memory system and a local memory area with which local data to be used by the processing section is registered and in which the registered local data is accessed by a local memory access instruction, which is different from the memory access instruction.
