Abstract

A first load instruction specifying a first virtual address misses in a data cache. A delta value is received based on a program counter value of the first load instruction. A second virtual address is computed based on the delta value and the first virtual address. Data associated with the second virtual address is then prefetched from a main memory to the data cache prior to a second load instruction specifying the second virtual address missing in the data cache.
