Method for canceling partial line fetch for cache when new data is requested during current fetch and invalidating portion of previously fetched data |
摘要 |
When a processor (102) issues a request for an address (502), a determination is made as to whether or not the address is contained within a buffer (103) or cache associated with the processor (102), or the address is contained within a line of data currently being fetched from an external memory system (105). If the address is not contained within the buffer or cache and is not contained within a line being currently fetched, the current fetch will be cancelled (515, 516).
