If zero-address architecture programs are longer (have more instructions) than one- or two-address architecture programs, this is feasible. Why?

This makes it more probable that applications written for 0-, 1-, and 2-address architectures will be more involved (have more instructions). Why?

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.

As a simple model of a bus-based multiprocessor system without caching, suppose that one instruction in every four references memory, and that a memory reference occupies the bus for an entire instruction time. If the bus is busy, the requesting CPU is put into a FIFO queue. How much faster will a 64-CPU system run than a 1-CPU system?

Computer Architecture Consider the below one-bus organization find the micro-operations at each step for the following instructions: 1- Instruction Load (100), R4 (R4 M[M[100]]) 2- JUMP X, where X is a memory location that contains the address of the instruction to be executed
