Abstract

PURPOSE:To realize an asynchronous logical circuit which attains an expected logical purpose, by supplying clock inputs to J-KFF and a data latch from an OR array independently of each other. CONSTITUTION:Clock input CK to J-KFF10 is supplied from OR array 2 independently, and clock input CK to data latch 11 is also supplied from array 2 independently. Consequently, each clock input is programmable freely and independently, so the FF and data latch can be operated asynchronously. Then, every tim input data 3 changes, a succession of cascaded changes occurs internally, so that the asynchronous logical circuit can be obtained which attains the expected logical purpose.
