You want to calculate the performance (bandwidth) of the following busses. You have a synchronous bus with the following specifications: 60Mhz frequency, 16.7ns clock cycle (CK), sending address/data takes 1 CK each, and a 100ns memory access time. You also have an asynchronous with the following specifications: each handshake takes 30ns, with the same 100ns memory access time. Assume 4 bytes of data to be transferred across the bus. Which bus has better bandwidth?
