Assume: CPU Clock = 1 GHz 1 OP requires 5 clock cycles (arithmetic instruction, conditional, etc.) 1 memory access requires 100 clock cycles (Read or Write) Problem size: N = 1,000,000 (1 million) There is no cost associated with the loop index variable: do not count any arithmetic instructions for initializing or incrementing the loop index value, do not count any memory accesses for accessing and using the loop index variable in your computation of a sum. Assume the loop index variable is "free of charge" There is no memory cost of accessing and updating your accumulator variable (e.g., sum += ...), but there is an arithmetic operation involved in updating the accumulator variable. Questions: 1. For algorithm #1 shown below (direct sum): • How many arithmetic instructions are required by this algorithm? • How many memory accesses are required by this algorithm? • How many clocks are required by this algorithm? • What is the CPI (cycles per instruction) required by this algorithm? •…

a) A computer has a clock rate of 2GHz. It takes a program 10s to complete on this computer. The number of clock cycles of the program is b) A program has 1x106 instructions. The computer's clock cycle time is 250x10-12 seconds and the CPI is 2.0. Therefore, the CPU time of the program is seconds. c) We use a certain compression program as a benchmark of a certain computer system. The program has 2x10° instructions. The system has a CPI of 0.85, and a clock cycle time of 0.4x109 seconds. When we run the program, it takes 100 seconds to complete on the computer system, whereas it takes 900 seconds to complete on a reference computer. From what you know about the SPEC benchmarks, the SPECratio is

Please refer to this textbook: “A. Silberschatz, P. B. Galvin and G. Gagne, “Operating System Principles,”7th Edition, John Wiley & Sons Inc., 2006.” And answer the following questions: Question:22 Assume Program X and Program Y run in different processes. At some time point, the two programs need to exchange data with each other. A. Can the data exchange be made as efficient as if the two programs were run by different threads in the same process? If so, explain how this can be done. If not, please describe the technical issues. B. If Y needs to wait for X, explain how this can be achieved with a semaphore.

NAND2TETRIS HARDWARE SIMULATOR How would i create this chip in hdl (hardware description language) HiLoMux - This has one 8-bit input bus, in, and one 4-bit output bus, out. Alsopresent is a sel input, which is used to select what appears on out. Ifsel is false, then out should contain the lower 4-bits of in (i.e. in[0],in[1], in[2], in[3]). If sel is true, then out should contain theupper 4-bits of in (i.e. in[4] mapped to out[0], in[5], mapped toout[1], etc.). In other words, the HiLoMux can be used to select anibble from a byte… this is what ive got so far CHIP HiLoMux{ IN in[8], sel; OUT out[4]; PARTS: }
a) During class, we spent time discussing how the computer (LPU) processes inp and creates output. Now, imagine you are explaining this same process to a fellow classmate. In your own words, describe how the CPU processes input from the keyboard and creates output to a computer monitor. Write one paragraph explaining this complex process and include the following terminology in your description: fetch, interpret, execute, control unit, arithmetic logic unit, memory unit, input, and output. 1
