Abstract
A system and method are provided for efficient handling of streaming-data in a cache memory system (105) having a cache with several cache-lines (160) capable of storing data. In one aspect, a method is provided for determining before storing data to a cache-line if the storing of data will replace earlier data already stored in cache (135). If the storing of data will replace data in the cache (135), it is determined if the data that will be replaced is streaming-data. If the data to be replaced is not streaming-data, it is stored into victim cache (155). However, if the data to be replaced is streaming-data, it is not stored into the victim cache, thereby improving system efficiency by eliminating the copying of data to be replaced and avoiding replacing other earlier data in victim cache (155) that may be needed in the future.
