2) (10 points) Consider a microprocessor driven by an 8-MHz input clock, with a 16-bit external data bus. Assume that this microprocessor has a bus cycle whose minimum duration equals 4 input clock cycles. A bus cycle is the number of clock cycles required to accomplish a task (such as data transfer). What is the maximum data transfer rate across the bus that this microprocessor can sustain, in bytes?

A byte-addressable memory system contains four memory modules each of which is 32 bits wide by 2^28 cells deep. The system employs a 1 MB 2-way set associative cache with 128-byte cache lines. It also uses a 32-bit CPU-to-memory data bus as well as 32-bit physical addresses. Each memory module requires 4 clock cycles to perform either a read or a write operation. a) Assuming that the memory system is low order interleaved, show the proper 32-bit format for physical...

1. A hard disk drive transfers data 8 bytes at a time and has a peak data rate of 8 MB/s. To make sure old data is not overwritten by new data in the device buffer during an input operation, the processor must sample the buffer at a rate of 8 MB/81000 K times per second Assume that each such interrogation and the associated data transfer takes 800 clock cycles in a processor with a 2.5 GHz. What fraction of...
