Abstract

PURPOSE:To get rid of a dead machine cycle, and to process an instruction efficiently, by selecting an output of an address generating circuit, and controlling a general purpose register. CONSTITUTION:The second address generating circuit 20 receives an output of an instruction decoding circuit 8, generates an address and inputs it to a comparing circuit 24 and an address selecting circuit 22. An output address of the first address generating circuit 10 is also inputted to the comparing circuit 24 and the address selecting circuit 22. The output address of the address generating circuit 10 is inputted to the address selecting circuit 22 through the third address generating circuit 21. This input signal is delayed by a constant interval of time from the output of the first address generating circuit 10. To the address selecting circuit 22, the outputs of each address generating circuit 10, 20 and 21 are inputted. The address selecting circuit 22 selects outputs of 3 kinds and drives a general purpose register 9.
