MEMORY CONTROL UNIT AND MEMORY CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To obtain a memory control unit facilitating cache management of data stored in a memory.

SOLUTION: The cache management of processing data in the memory can be performed easily by controlling using an upper-level counter incrementing each time a block counter exceeds a number storable in the memory, in addition to the block counter incrementing at the time one block is completed in each processing means. Also, with the provision of an error correction result decision circuit, control signal generation for permitting the operation of each processing is masked when error correction cannot be performed.
