PURPOSE:To efficiently execute a signal processing by selecting objective combination from an input signal, the input/output signals of a storage element, the input/output signals of a logical circuit, the input/output signals of the other selectors and the like through the use of a programmable selector. CONSTITUTION:A signal which is inputted to D in FF2 selects the signal of an input terminal 1, the Q output of its own FF2, and the Q output of other FF3, by a selector 6. For the clock inputs CK to FF2, two clocks CLK1 and CLK2 are selected in a selector 7 and inputted. For the inputs of a logical circuit 5, they are similarly selected in selectors 11 and 12. Thus, the signal processing can efficiently be executed by constituting the title circuit by selectors 6, 7, 8, 9 and 10, the selectors 11 and 12 which programmably select the inputs of an assembly logical circuit 5 and a selector 14 which programmably selects an output for an output terminal 13. |
