Abstract
A control method for a data processing circuit which controls the timing of two clocks which independently control data latch circuits connected respectively with an input side and an output side of a logic circuit. The two clocks are held at a level which allows both data latch circuits to sample an input signal for a predetermined period. A data latch circuit comprises a first gate controlling whether or not an input signal is conducted to the logic circuit, an input end of a buffer circuit for latching the data signal and an output end of a second gate which causes an output of the buffer circuit to pass to an output end of the first gate, and a data processing circuit capable of sampling data, logically processing it, latching the result of the processing, and outputting it in one clock cycle, by interposing a logic circuit between the aforementioned two data latch circuits.
