Abstract
PURPOSE:To shorten instruction execution time by inputting only the discrimination part of a read instruction to a microprogram address generating circuit by providing an instruction read gate between the storage device of a central processor and the microprogram address generating circuit. CONSTITUTION:An instruction (i) read out of a storage device 1 in response to a request from a central processor is stored in an instruction register 4 by a data switching circuit 2, and its discrimination part (j) is inputted from a route 12 via a gate 11 to a microprogram address generating circuit 7. The circuit 7 outputs the starting address (k) of a microprogram, which corresponds to be instruction (i), in a control storage device 9 on the basis of the discrimination part (j) to transfer it to a control storage address control circuit 8. The circuit 8 reads the starting microinstruction l of the microprogram corresponding to the instruction (i) from the address (k) and stores it in a microinstruction register 10. On the basis of the microinstruction l, the registor 10 operates each circuit of the central processing system device.
