Abstract:
1. A method for performing clocked operations in an electronic device, the method comprising the steps of: performing, in the electronic device, first and second operations responsive to a timing clock having a primary frequency f, wherein the electronic device is capable of performing the operations within X and Y cycles of the clock, respectively, and wherein X cycles of the clock correspond to a time interval T generating, during the time interval T masking a certain effect of the at least one extra cycle of the clock for the second operation, so that instances of the second operation during the interval T wherein a first clock signal has the primary frequency f and a second clock signal has a frequency greater than the primary frequency f, and wherein generating the at least one extra cycle of the clock comprises selecting, during some of the time T wherein instances of the second operation are initiated by asserting an operation-initiating control signal in conjunction with asserting the timing clock, and wherein masking the effect of the at least one extra cycle of the clock comprises altering timing of the control signal, so that assertion of the control signal occurs during a different time interval than does assertion of the at least one extra cycle of the clock.
