Multiple input-multiple clock maintenance obstruction type JK trigger

Abstract

The invention discloses a multiple input-multiple clock maintenance obstruction type JK trigger which comprises a multiple input basic RS latch register, two or more input units and JK converting circuits. Two output terminals of the multiple input basic latch register are q and nq respectively. Quantities of the input units and the JK converting circuits are same. Two output terminals of any input unit are connected to an input terminal of the multiple input basic latch register respectively to form a maintenance obstruction type D trigger. The input units comprise data input terminals and clock trigger ends. The data input terminals of the input units connect with output terminals of the JK converting circuits. The JK converting circuits have two data input terminals. The multiple input-multiple clock maintenance obstruction type JK trigger can be used as a common memory, and can be applied to design of a sequential circuit, especially design of a distributed system and an asynchronous circuit of event driven. Compared with a present trigger, according to the multiple input-multiple clock maintenance obstruction type JK trigger, in the case of multipath data input, direct event driving is employed, a data selection circuit is simple, and a storing speed is rapid.

Description

technical field [0001] The invention belongs to the field of electronic technology, and in particular relates to a flip-flop circuit, in particular to a maintenance blocking JK flip-flop with multiple data input channels and multiple clock terminals and a circuit with trigger priority. Background technique [0002] Flip-flop is a device with storage function, which is used to form various sequential logic circuits in digital electronic technology. There are many types of flip-flops: according to the trigger mode, it is divided into level trigger, master-slave trigger, and edge trigger; according to the logic function, it is divided into RS flip-flop, D flip-flop, JK flip-flop, T flip-flop, etc. The characteristics of the trigger are described by the trigger mode and logic function. The trigger mode is used to determine the characteristics of the state change, that is, the way to receive the input signal to change the state; the logic function determines the direction of the ...
