Answer the above questions

A. The IT department of your organization is evaluating a new system to be purchased and because of your registration in the course of COSS, the manager has asked you to take up the responsibility of running an appropriate benchmark application. The processor clock speed in this new system that is getting evaluated is 150MHz. When you decided on a benchmark application and analyzed its instruction mix, you observed that the instruction mix was approximately around 40% load & store instructions, 35% was arithmetic instructions and the balance was miscellaneous instructions. On an average, the load and store instruction was taking 5 cycles, Arithmetic instruction was taking 10 cycles and the miscellaneous instruction was taking 3 cycles. For the purposes of this specific benchmark application, lets assume that the processor is executing one instruction at a time a)Calculate the CPI for this chosen benchmark application. [1M) b)Calculate the "MIPS" processor speed for the benchmark in millions of instructions per second? [1M] c)If for some reason, the cycle time has to be increased by 25%, what would the new clock speed be? [2M] B. a)For a given disk, it is mentioned that are 10K bits for every 2 inches segment of a track and there are 10 tracks in a radial segment of an inch. Calculate the areal density of the mentioned hard disk [2M] b)Given the disk characteristics as having 1024 bytes per Sectors, disk rotation rate as 10000 revolutions per second, average seek time as 9 micro seconds, with 600 sectors per track, calculate the total access time that will be encountered for this disk (1M] c)For this same disk that is mentioned in (b), if there are 2048 bits per sector, is the cost (in terms of TIME units) of accessing the first bit the same as accessing the 1024th bit of the sector? Justify your answer I1M
