Title: Arithmetic circuit and arithmetic method
Inventor: GOTO KOJI
IPC: G06F9/32
Filed: 1995-07-24
Abstract: PROBLEM TO BE SOLVED: To shorten processing time for condition branching and to reduce the power consumption of an arithmetic circuit by selecting the value area, where the arithmetic result of an ALU is included, at an address unit. SOLUTION: When a clock CLKB is turned to 'H', a result register 1 stores the processing results of an ALU 3 and outputs only the arithmetic result of the stored values to a value area discriminating circuit 7 and the value area discriminated result of input data is decoded by a decoder 40 and outputted to a signal line 8. Only when an instruction code bit on a signal line 11 shows a condition branching instruction due to the value area discrimination, a selector 9 selects the data on the signal line 8 and outputs them to a signal line 14. On the other hand, a latch 15 stores a current PC value and outputs it to a signal line 17. An adder 18 adds the output of the latch 15 and the data on the signal line 14 in each machine cycle and outputs them to a signal line 19. A selector 23 selects the data on the signal line 19 and an instruction code and outputs them to a signal line 25.  Thus, condition branching in an instruction ROM can be executed.
