6. A processor having a clock cycle time of 0.25 nsec will have a clock rate of ------------MHz.

7. A program is running on a machine which has a total of 500 instructions, average cycles per instruction for the program is 2.5, and CPU clock rate is 1.78GHz.The execution time of the program will be --------------------- second.

8. Consider a program whose instruction count is 60,000, average CPI is 2.4 and clock rate is 1.9 GHz. Suppose we use a new compiler on the same program for which the new instruction count is 50,000 and new CPI is 4.1, which is running on a faster machine with clock rate 2.5GHz. The speedup achieved will be..................

9. Consider a processor having four types of instruction classes, A, B, C and D, with the corresponding CPI values 1.3, 1.9, 2.5 and 3.8 respectively. The processor runs at a clock rate of 2 GHz. For a given program, the instruction counts for the four types of instruction are 25, 15, 10 and 5 million respectively. The MIPS rating of the processor for this program will be...................

10. Perform signed magnitude multiplication to calculate m * n. (m is the sum of last four digits of your register number, n is the negative value of the sum of last two digit in register number. For eg. Reg no: 19bce0453, then m = 0+4+5+3=12 and n = - 8).
