Abstract:

The patent describes a counting-register whose enabling signal can be chosen from one of a group of synchronous frequencies for real-time measurement or from an incrementing signal from an iterative loop in a computer. This convertible register comprises two four-bit counters connected in series, and AND gate and a multiplexer to provide an enabling signal at one of the above-stated frequencies to the AND gate which applies the enable signal to the counters if the output from the last of the series counters is a one.
