在sdk调试ddr的时候,想要使用memory窗口观察写入情况,需要使用到Xil_DCacheInvalidateRange函数无效化数据缓存,memory窗口才能刷新最新的数据。 Xil_DCacheInvalidateRange 这个函数用于无效化指定范围内的数据缓存。当你无效化缓存时,缓存中的数据将被标记为无效,但是并不会写回主存储器。这在你确定缓存中的数据已经过时...

To flush and invalidate the data cache, use the OEMCacheRangeFlush function instead.This function is called by the kernel to flush and invalidate the data cache. The data cache is flushed/invalidated when CacheSync is called.Copy void FlushDCache(void); ...
对处理器而言,清除操作只要清零相应cache行的有效位即可。当存储器配置上有变化时,整体或部分cache可能需要进行清除(flush)操作。有时也用术语作废(invalidate)来代替术语“清除(flush)”。然而,对于采用写回策略的D-cache,就需要使用清理(clean)操作(注:dcache也有flush(清除)操作,见flush_dcache_range函数)。
The data cache flush function OEMCacheRangeFlush is called to flush the data cache by determining how many cache lines are available and then flushing each line until all lines have been flushed.Note The old data cache flush function, FlushDCache, is deprecated and should never be used.OEM...
This function replaces calls to FlushDCache, FlushICache, and TLBClear in Windows CE .NET 4.2 and later.pAddr=NULL and dwLength=0 is a special case, which means all addresses.For example, the call OEMCacheRangeFlush(NULL, 0, CACHE_SYNC_FLUSH_TLB) flushes the data in the TLB. OEM...
