Abstract

A memory controller is configured to receive read requests from a processor and return memory words from memory. The memory controller comprises an address comparator and a loop entry cache. The address comparator is configured to determine a difference between a previous read request address and a current read request address. The address comparator is also configured to determine whether the difference is positive and less than a certain address difference and, if so, indicate a limited backwards jump. The loop entry cache is configured to store a current memory word for the current read request address when the address comparator indicates a limited backwards jump.
