> The only thing this patent covers is the physical circuit implementation

The claims in that patent are not limited to a physical circuit implementation.

The description includes a circuit diagram as one possible embodiment of the claimed invention, but the patent covers any implementation (and the description indicates it was intended to cover instructions running on general purpose processors).
