ABSTRACT:
This invention provides a circuit and a method for programmable counters. It consists of a circuit and a method for unique programmable counters that provide half-integral as well as integral steps, such as 1.5, 2, 2.5, 3, 3.5, 4. This circuit and method are the first implementations of providing programmable counting with half-integral steps. The circuit and method of this invention can be extended via the cascading of toggle flip flops at the front end of the circuit of this invention. This provides the ability to enhance the speed of normal integral step counting applications. In addition, the cascading of the multiple copies of the circuit of this invention provides the ability to provide other fractional programmable counters. A key advantage of this invention is that the method of this invention is general enough to use any other type of counter sub-component beside the binary counter sub-component of this invention.
