Given that
CPI = 1.5
Frequency = 2 GHz = 2 x 109
Thus, the given program with 10 billion instructions would take 7.5 seconds to execute on a intel processor with a clock period of 0.5 ns.
Hence, the intel processor has shown a 0.8 times speed up relative to AMD processor.

Suppose a program (or a program task) takes 1 billion instructions to execute on a processor running at 2 GHz. Suppose also that 50% of the instructions execute in 3 clock cycles, 30% execute in 4 clock cycles, and 20% execute in 5 clock cycles. What is the execution time for the program or task?
5. If a processor clock ticks 4 billion times in a second and has a frequency of 1.5 GHz, with each clock tick, one or more instructions may complete, if a program runs on 3 GHz processor for 7 seconds, how many clock cycles did it run for? (10 points) If a program runs for 2 billion clock cycles on a 1.5 GHz processor, what is the execution time in seconds? (10 points)

A program (or a program task) takes 150 million instructions to execute on a processor running at 2.7 GHz. Suppose that 50% of the instructions execute in 3 clock cycles, 30% execute in 4 clock cycles, and 20% execute in 5 clock cycles. What is the execution time for the program or task? Suppose the processor in the previous question part is redesigned so that all instructions that initially executed in 5 cycles and all instructions executed in 4 cycles...
Computer A executes the MIPS ISA and computer B executes the x86 ISA. On average, programs execute 1.5 times as many MIPS instructions as x86 instructions. Computer A has an average CPI of 1.5 and computer B an average CPI of 3. If computer B runs at a 3GHz clock frequency, what speed does computer A have to run at to be at least as fast as computer B?

A non-pipelined processor has a clock rate of 1 GHz and an average instruction takes 9 cycles to execute. The manufacturer has decided to design a pipelined version of this processor. For this purpose, the instruction cycle has been divided into five stages with the following latencies: Stage 1 – 2.0 ns,Stage 2 – 1.5 ns, Stage 3 – 1.0 ns, Stage 4 – 2.6 ns, Stage 5 – 1.9 ns. Each stage will require an extra 0.4 ns for...
