Abstract: A controller sets a selector register of programmable delay signal logic is to a value equal to a required number of clock cycles of delay for signals output from an integrated circuit to an external memory. The controller controls a selection of additional logic along the output path to perform on the delayed signal within a clock cycle without any latency added to the output path by delay signal logic outputting the delayed signal. The controller waits required number of clock cycles after setting the selector register before using the delayed signal output by the delay signal logic onto an output path.

Abstract: A logic unit is configured with least one multiplexor distributed along a delay path of a logic unit, wherein each at least one multiplexor is configured to receive two inputs and output one of the two inputs, wherein each at least one multiplexor is configured to select one of the two inputs to control a particular programmable number of clock cycles of delay added to a signal from 1 to N clock cycles. The logic unit is configured with at least two latches distributed along the delay path of the logic unit, wherein each at least one latch is configured to add a clock cycle of delay, wherein a terminating latch from among the at least two latches is configured to output the signal delayed by the particular programmable number of clock cycles.
