$\backslash$table$[[$Instruction class,Clock Cycles per Instruction,Frequency of appearance$],[$Branch$,3,18\%],[$Store$,4,23\%],[$Load$,5,32\%],[$ALU$/$R$-$Type,$4,27\%]]$

a$)$ If the program execution time is $8s,$ and that the number of Load instructions is $260,000$ what is the clock cycle of the computer and the frequency that the computer runs at$?$

b$)$ How much does the CPI for the Load instructions have to be reduced to gain $10\%$ reduction in execution time?

c$)$ Assume that a computer system has a processor with $10$ cores that can be used to solve a problem in parallel. $98\%$ of the code is parallelizable. Can the system achieve a speedup of $10?$
