64 Bit Binary Counter with Minimal Clock Period

Abstract

Novel rapid formations of synchronous binary counting with single minimum period of counting for practical counters are developed in this project. A synchronous binary counter is required in many applications since it is rapid, also can help a broad bit-width. Basically, because of massive fan-outs and extensive carry chains, earlier counters have a limited counting rate, mainly when size of the counter is not modest. It employs a single bit Johnson counter to decrease whole hardware complications, then copy it to lessen the propagation latency caused by huge fan-outs. In this paper, re programmable the clock utilized in it for various applications functioning at different clock rates and there’ll be a variation within the delay values because the clock is reprogrammed the critical may varies for various rates. The counter output results are obtained for various bit up to 64 and therefore the design provides various clock rates with variations in area and delay.
