Filed: 1998-01-14
Abstract: PROBLEM TO BE SOLVED: To sufficiently utilize the merit capable of a highspeed memory read operation by successively fetching data from respective data holding circuits and outputting an address for the next memory access. SOLUTION: By holding the data outputted from respective ROMs 10-13 by data latch units 20-23, a CPU 1 fetches the data from the data latch units 20-23. Thus, the need of continuously outputting the address N to the ROMs 10-13 through an address bus 3 by the CPU 1 is eliminated, the next address (N+16) is outputted and shifted to the memory read operation of the next time. As a result, by the next clock after outputting the data (N+12) from the data latch unit 23 to a data bus 4, the data (N+16) are outputted from the ROM 10 to the data bus 4. Thus, the time after the data are outputted from the ROM 13 to the data bus 4 until the data are outputted from the ROM 10 to the data bus 4 is shortened.
