摘要： A command processing apparatus and method are provided for optimally processing commands issued asynchronously from a plurality of masters to a storage apparatus including a plurality of banks, where each master issues commands for a bank 0 and a bank 1 alternately. The command processing apparatus includes buffer units that obtain commands issued from the plurality of masters, an arbitration unit that arbitrates the obtained commands, and an issuance unit that issues commands to the storage apparatus according to the arbitration. The arbitration unit reads the commands of the plurality of masters obtained in the buffer units, and selects one command as a result of arbitration. The arbitration unit waits until a next command of a master relating to the selected command becomes readable, and reads the next command. The issuance unit consecutively issues the selected command and the read command to the storage apparatus.

摘要： A cache memory system which readily accepts software control for processing includes: a cache memory provided between a processor and memory; and a TAC (Transfer and Attribute Controller) for controlling the cache memory. The TAC receives a command which indicates a transfer and an attribute operation of cache data and a target for the operation, resulting from the execution of a predetermined instruction by the processor, so as to request the operation indicated by the command against the address to the cache memory.

摘要： The cache memory in the present invention is a cache entry having, in a correspondence with a cache entry which holds a data unit of caching, a valid flag indicating whether or not the cache entry is valid, and a dirty flag indicating whether or not the cache entry has been written into. The cache memory in the present invention includes an altering unit which, based on an instruction from a processor, sets, in the cache entry, an address serving as a tag and sets the valid flag, without loading data from a memory, or resets the dirty flag in a state in which the cache entry holds rewritten data that has not been written back.
摘要翻译：本发明的高速缓冲存储器是具有与保存缓存的数据单位的高速缓存条目相对应的高速缓存条目，表示高速缓存条目是否有效的有效标志，以及指示是否缓存条目已经写入。本发明的高速缓冲存储器包括：改变单元，其基于来自处理器的指令，在高速缓存条目中设置用作标签的地址，并且设置有效标志，而不从存储器加载数据，或者重置在高速缓存条目保存未被写回的重写数据的状态下的脏标志。
