Abstract
A cache controller with an improved cache memory refill operation is presented. After a request from a CPU for a word of information and the word is not found in the cache memory, the cache controller starts a refill operation by which a line of information including the requested word is loaded into the cache memory from a main memory. The cache controller keeps track of the CPU requests. When a requested word appears during the refill operation, the CPU is notified to load the requested word as the word is loaded into the cache memory. Furthermore, the cache controller efficiently takes advantage of free cycles in the refill operation. If the CPU has requested a word in the cache memory, the cache controller reads the word from the cache memory so the CPU can load the word during a free cycle.
