5. Consider two different implementations, M1 and M2, of the same instruction set. There are three classes of instructions (A, B, and C) in the instruction set. M1 has a clock rate of 80 MHz and M2 has a clock rate of 100 MHz. The average number of cycles for each instruction class and their frequencies (for a typical program) are as follows. Calculate the average CPI for each machine, M1, and M2. Instruction Machine M1 class CPI 1 B 2 4 Machine M2 Frequency CPI 2 60% 3 30% 4 10% 6. Translate the following high-level code to RISC-V assembly. vals is an array of words (4 bytes) whose base address is in x22. i and sum variables are in x5 and x6 registers, respectively: int i=0; int sum=0; while (vals[i]!=0) { sum=sum+vals[i]; i++; } 7. Translate the following high-level code to RISC-V assembly: for (i=0;i
