<p>PROBLEM TO BE SOLVED: To provide a memory control device which sets order of priority to a memory access and efficiently mediates a memory access demand so that they do not fail. SOLUTION: In a memory control device which mediates a memory access for allowing an access demand to a buffer memory from plural circuit blocks including error correction blocks for requiring N times of accesses to the buffer memory according to predetermined order of priority during a specified frame term T, the device has a comparison means 24 having a numerical value M predetermined as a comparison reference value and an up down count means 25 which counts up every cycle T/(N+M) and, if the memory access is allowed, counts down. The count value of the up down count means 25 and the reference value M are compared by the comparison means 24 and the order of priority of the error correction block is changed in accordance with the comparison output.</p> |
