Abstract
A memory control apparatus disposed in a memory access system having a bus, a single storage unit with a bank structure and a bus arbitrating unit, includes: an access-request accepting means for accepting sequential access requests for data located at sequential addresses in the storage unit, sequential access requests for data located at discrete addresses in the storage unit as sequential access requests, or access requests for data located at sequential addresses in the storage unit which cannot be made into a single access request as sequential access requests; and an access-request rearranging means for rearranging sequential access requests accepted by the access-request accepting means in an order of banks of the storage unit within a range of access requests relating to either a data write request output from one of data processing units or a data read request output therefrom to control an access control of the storage unit.
