INTERFACE DEVICE AND METHOD FOR EXTENDING MEMORY BAND WIDTH

摘要

PURPOSE: An interface device and method for extending a memory band width is provided to enhance a using efficiency with respect to a sharing memory access band width by detecting inputted data storing commands and performing a sharing memory access with respect to data storing commands in a bundle. CONSTITUTION: An external interface unit(31) is provided for an interface with an exterior. A temporary storing unit(32) temporarily stores a storing command being inputted from the exterior. A detecting unit(33) detects a sharing memory storing operation. An access control unit(34) controls a sharing memory access with respect to a storing command by considering a result.
