ABSTRACT:
A controller interface between a processor and a coprocessor is described. The controller is coupled to the processor to provide a processor interface for operating at a first frequency, where the first frequency is a frequency of operation of the processor. The controller is coupled to the coprocessor to provide a coprocessor interface for operating at a second frequency, where the second frequency is a frequency of operation of the coprocessor which is slower than or equal to the first frequency. The controller is configured to operate at both the first frequency and the second frequency providing in part handshaking between the processor and the coprocessor such that the processor does not have to be slowed down to the second frequency for operation with the coprocessor.
