Abstract

See full text

A clock generator circuit for providing a clock signal to a dual-edged D-type flip-flop, enabling the flip-flop to be dual edged, single edged, or to enable a user to provide clock edge selection, asynchronous clocking, clock enabling, or a mixture of different type clock signals. The clock generator circuit includes inputs receiving first and second enables signals and a clock signal. The clock generator circuit further includes circuitry to provides an output clock signal which transitions when a rising edge of a pulse of the clock signal is received when the first clock signal is enabled, or if a falling edge of a pulse of the clock signal is received when the second clock signal is enabled.
