ABSTRACT:
A phase delay compensator apparatus is provided which compensates for the phase error caused by propagation delay differences between clock and data paths within a computer system. A look-up table circuit is used to dynamically translate a change in frequency of the computer system clock or a change in the length of cable connecting the computer's sub-assemblies to a binary bit pattern defining the requisite phase-shift between distributed clock and data signals. A generator circuit produces phases of the phase-shifted clock signals, while ensuring the integrity of the loaded binary bit pattern. A gated signal is created for enabling the generator circuit.
