<p>PURPOSE:To operate a high speed processing by providing a comparator which inputs the data of an ROM from one input and inputs the output of an another exclusive memory from the other input, stopping a program counter at the time of the coincidence of the resulted result, and inputting the output of the exclusive memory by an instruction decoder. CONSTITUTION:This device is equipped with an exclusive storage device 4 which is different from a storage device 2, and a comparator 5 which compares the data outputted from the storage device 2 with the data of the exclusive storage device 4. Then, when the two data are coincident with each other, the output of the comparator 5 stops the increment of a program counter 1, encourage the increment of a counter 6 which designates the address of the exclusive storage device 4, and the content of the exclusive storage device 4 is turned into the input of an instruction decoder 3. That is, a command group stored in the memory 4 except for the ROM 2 can be turned into the input of the instruction decoder 3 instead of the output of the ROM 2, so that the command group can be written in the exclusive memory 4 as one command as the data of the ROM 3. Thus, an ROM efficiency is improved, and the high speed operation is attained.</p> |
