ABSTRACT:
Method and apparatus for communicating numeric data between first and second circuits incorporating a controller communicatively coupled to the first circuit to receive the numeric data, and an accumulator communicatively coupled to the second circuit and the controller, the accumulator comprising accumulator logic managing reference data, the controller being responsive to the numeric data selectively causing the accumulator logic to increment or decrement the reference data to match the numeric data. The accumulator will notify the second circuit of the so-updated reference data. In one embodiment, three signal lines (UP, DN, CLK) are used by the controller to direct the accumulator to increment, decrement, reset or hold the reference data. In another embodiment, only two signal lines are used at the expense of reset complexity.
