Consider a 32-bit microprocessor, with a 16-bit external data bus, driven by an 8-MHz input clock. Assume that this microprocessor has a bus cycle whose minimum duration equals four input clock cycles. What is the maximum data transfer rate across the bus that this microprocessor can sustain in bytes/s? To increase its performance, would it be better to make its external data bus 32 bits or to double the external clock fre- quency supplied to the microprocessor? State any other assumptions you make and explain. Hint: Determine the number of bytes that can be transferred per bus cycle.

Transcribed Image Text:Consider a 32-bit microprocessor, with a 16-bit external data bus, driven by an 8-MHz
input clock. Assume that this microprocessor has a bus cycle whose minimum duration
equals four input clock cycles. What is the maximum data transfer rate across the bus
that this microprocessor can sustain in bytes/s? To increase its performance, would it
be better to make its external data bus 32 bits or to double the external clock fre-
quency supplied to the microprocessor? State any other assumptions you make and
explain. Hint: Determine the number of bytes that can be transferred per bus cycle.
