ABSTRACT:
A microprocessor based computer system is provided which includes a reset circuit having a phase error detector for detecting a phase error between an initial reset signal and a clock signal provided to the microprocessor clock input. The reset circuit further includes a phase error corrector for adjusting the phase of the clock signal if a phase error is detected so as to substantially minimize the phase error. The reset circuit includes a reset signal regenerator for providing a new reset signal to the reset input of the microprocessor when the phase of the clock signal is adjusted.
