Abstract
The present invention is directed to a method and system for measuring bus frequency. A system suitable for determining bus frequency may include a bus device and a processor. The bus device is suitable for performing an operation and the processor is communicatively coupled to the bus device utilizing a bus. The processor is capable of starting a timer, initiating the bus device to perform a number of operations, receiving an indication that the bus device completed the number of operations, stopping the timer when the indication is received. A bus clock frequency is computed based upon time taken to complete the number of operations as indicated by the timer and the number of operations performed by the bus device.
