  • Method for synchronizing graphics processing units
    Patent number: 7859542
    Abstract: A method for synchronizing two of more graphics processing units. The method includes the steps of determining whether the phase of a first timing signal of a first graphics processing unit and the phase of a second timing signal of a second graphics processing unit are synchronized, and adjusting the frequency of the first timing signal to the frequency of the second timing signal if the first timing signal and the second timing signal are not synchronized.
    Type: Grant
