Disclosed herein is a memory access control circuit including: a determination section adapted to determine whether a target requested by a first wraparound memory access request from a processor is stored in a prefetch buffer; a request generation section adapted to generate a second wraparound memory access request including the target if it is determined that the target is not stored in the prefetch buffer; and an address conversion section adapted to convert the start address of the first wraparound memory access request according to predetermined rules for use as a start address of the second wraparound memory access request.
