How do the previously noted problems in the Whetstone, Dhrystone, and Linpack benchmarks become addressed by the SPEC CPU benchmarks?

What problems do the SPEC CPU benchmarks solve that the Whetstone, Dhrystone, and Linpack benchmarks don't?

A benchmark program to evaluate the performance of a processor spends 80% of its time on floating-point commands and 20% on non-floating point commands. A design team wants to obtain an overall speedup of 40% over the existing run time of this benchmark program by speeding up ONLY the non-floating point commands. What should be the ratio of the non-floating point commands new runtime to that of its old runtime? Select the best answer. This is a trick question! In this scenario, it is impossible to speed up only the non-floating point commands to obtain an overall 40% speedup! 2 0.5 2.5

Describe as many techniques used to achieve hardware parallelism (to improve processorperformance) in a short paragraph.

Using a better optimizing compiler is most likely to result in which one of the following improvements? Group of answer choices a) A lower CPI for ALU instructions b) Fewer ALU instructions being executed c) A faster clock frequency

The result for the SPEC CPU 2017 Integer Speed Result on an Intel Xeon Platinum 8490Hprocessor. This system has an enabled 120 cores, 2 chips and 2 threads/core where each benchmarkprogram is executed simultaneously on all 120 cores with the execution time and ratio for each test asshown on the table. Compute for the speed metric on base and peak.

Suppose you wanted to implement a control unit for a computer that you are designing. A. Would you use a hardwired implementation or a micro-programmed control unit?  Why?   I would use a micro-programmed control unit for my computer. The reason for this is because micro-programmed control units are easier to handle and make modifications. Also, modern processors that utilize the CISC architecture can convert code to be more RISC-like to be used internally. B. What factors in the computer design would affect your decision?   It depends on my intended plan for the device. If I were to design a personal computer for non-commercial use, I would more than likely implement micro-programmed control units. If I were to design microprocessors for use in embedded systems or mobile devices, I would use the hardwired control unit.

What innovations in pipelining and microarchitecture design are being explored to overcome the limitations posed by power consumption and heat dissipation in modern CPUs?
