(CPU A CPU B ) CPU A CPU B CPU S AziTech is considering the design of a new CPU for its new model of computer systems for 2021. It is considering choosing between two ( 2 ) CPU and implementations based on their performance . Both CPU are expected to have the same instruction set architecture . has a clock cycle time of 60 ns and has a clock cycle time of 75 ns . The same number of a particular instruction type is expected to be executed on both in order to determine which CPU would executes more instructions . able to execute 2MB of instructions in cycles . executes the same number of instructions in clock cycles a ) Using the MIPS performance metric , which of the two ( 2 ) CPU should be selected to be implemented in the new computer system . Justify your choice Marks ] ) Compute the execution time for both CPUs Which CPU is fuster ? [ 6 Marks CPU A 3^ * 10^ 6

A hard disk with one platter rotates at 15,000r=min and has 1024 tracks, each with 2048 sectors. The disk head starts at track 0 (tracks are numbered from 0 to 1023). The disk then receives a request to access a random sector on a random track. If the seek time of the disk head is 1ms for every 100 tracks it must cross:
a. What is the average seek time?
b. What is the average rotational latency?
c. What is the transfer time for a sector?
d. What is the total average time to resolve a request?
