Abstract
An arbitration and synchronization method and system for allowing multiple processors to access a shared memory includes an arbitrator. The arbitrator is operable with the processors for enabling each of the processors exclusive access to the memory for a predetermined time period on a rotating basis. In operation, a time period of a time frame is associated with each of the processors. The time periods of the time frame are then counted. The arbitrator then enables a processor to have exclusive access to the shared memory for the time period associated with the processor when the counted time period is the time period associated with the processor.
