摘要： A cache write back operation, write back modified data to memory from cache data array to fix inconsistency between them can be cancelled by the results of a comparison of the progress between a write back and snoop push or snoop kill operation. Write back is intended to make an empty slot to accommodate a reload data due to a cache miss and since a snoop push or snoop kill operation creates an invalid entry in the cache, write back is not needed. If simultaneous push or kill with write back operation exist, then write back machine is late cancelled. System performance improves due to preserving more cache lines in cache data array for possible future reuse.
摘要翻译：缓存回写操作，将缓存数据数组中的修改后的数据写回到内存中以修复它们之间的不一致，可以通过比较回写和窥探推送或窥探杀手操作之间的进度的结果来取消缓存。回写是为了使空槽容纳由于高速缓存未命中的重新加载数据，并且由于窥探推送或窥探杀手操作在高速缓存中创建无效条目，因此不需要回写。如果同时推送或者杀死与回写操作存在，则回写机器被取消。由于在缓存数据阵列中保留更多的高速缓存线，可能会再次使用系统性能。

摘要： The present invention provides parallel processing of write-back and reload operations in a cache system and optimum circuit utilisation by implementing moveable buffers in a cache storage. However, the data and associated pointers are not permanently assigned to a particular buffer—hence, the buffers can move logically around in the facility. Reload pointer is pointing to an empty entry so that retrieved data from the main memory or equal hierarchy cache on cache miss can be always be accommodated. Victim pointer is always pointing to a modified entry for the next candidate of write-back operation. Write-back operation is necessary with reload operation in order to make a free entry for further cache miss handling unless free entry exists. Because of these moveable pointers for reload buffer and victim buffer and integrated write-back buffer in the cache, intra cache data movement is not necessary which improves cache miss handling performance.
摘要翻译：本发明通过在高速缓存存储器中实现可移动缓冲器来提供缓存系统中的回写和重新加载操作的并行处理以及最佳的电路利用。然而，数据和相关联的指针不会永久分配给特定的缓冲区，因此缓冲区可以在设备中逻辑移动。重新加载指针指向一个空条目，以便始终可以容纳来自主存储器或高速缓存未命中的等分层缓存的检索数据。受害者指针总是指向下一个回写操作候选者的修改条目。为了进一步缓存未命中处理，进行空闲条目，除非有空条目存在，否则重写操作是必须的。由于这些用于缓存缓冲区和受影响缓冲区以及集成回写缓冲区的可移动指针，因此不需要内部缓存数据移动，这提高了缓存未命中处理性能。

摘要： In the structure of register files composed of a master register file and a working register file, when data is read, the working register file is accessed. When data is written, the both the master register file and the working register file are accessed. In the working register file, data of the current window, and data preceded thereby, and data followed thereby are stored. Thus, even if the SAVE instruction or the RESTORE instruction are successively executed, instructions can be processed out of order. As a result, the efficiency of the process is improved.
