A novel asynchronous ACS(add-compare-select) processor for Viterbi decoder is described.It is controlled by local handshake signals instead of the globe clock.The circuits of asynchronous adder unit,asynchronous
19. The CAM device of claim 18 further comprising circuitry to assert a first precharge enable signal to enable the first pair of precharge circuits to precharge the first match line of the first pair of match lines and the second match line of the second pair of match lines during a fi...
each individual flip-flop is clocked through the main clock signal or by an output of another flip-flop. Therefore, the speeds of the asynchronous logic circuits are much higher than the synchronous circuits. Even though asynchronous logic is efficient, they are difficult to design and implement ...
Latch and flip flops are basic building blocks of sequential logic circuits, hence the memory. A sequential logic circuit is a type of digital circuit which responds not only to the present inputs, but to the present state (or past) of the circuit. In order to achieve this functionality, ...
