PROBLEM TO BE SOLVED: To provide a low-cost memory control device for reading a memory from a CPU at a high speed. SOLUTION: This memory control device starts a memory read access at the time of setting an address and stores the read data in FIFO in a signal processor so as to perform the memory read access from the CPU at a high speed. The memory write is performed via FIFO and only when there in no vacant space in the FIFO, a wait signal to the CPU is made effective so as to perform the memory write from the CPU at a high speed.
