Digital counter used for recording big figure

Abstract

The invention is a digital counter used to record great number, composed of at least two counters. Its character: input end of each counter is set with enable inlet and clock inlet, and output end set with carry outlet, all the carry outlets are connected in parallel and connected with an aND circuit, all the count values are prime, when each carry outlet generates signal, the output signal of the AND circuit is the product of numbers of all the counters.

Description

Technical field: [0001] The invention relates to a counter, in particular to a digital counter for recording large numbers. Background technique: [0002] In the prior art, the counting value of the digital counter is mostly not large, and some can achieve a large counting value by using an integrated chip or a programmable logic gate array. However, when a single counter records a large value, it will be due to External interference signals or unstable factors of the clock cause errors in the counting results, which in turn affects the performance of the entire application system. Invention content: [0003] The technical problem to be solved by the present invention is: in the prior art, the counting value of the digital counter is mostly not big, what have adopts integrated chip or programmable logic gate array to be able to reach bigger counting value, but, because single counter carries out When counting a large value, the counting result will have errors due to exte...
