During the execution of instructions, if an instruction is executed, then next instruction is executed only when the data is read by Correct Answer bus interface unit

During the execution of instructions, only after the bus interface unit of CPU reads the data from the main memory and returns it to the register, the next instruction execution will commence.

A 5-stage pipelined processor has Instruction Fetch (IF), Instruction Decode (ID), Operand Fetch (OF), Perform Operation (PO) and Write Operand (WO) stages. The IF, ID, OF and WO stages take 1 clock cycle each for any instruction. The PO stage takes 1 clock cycle for ADD and SUB instructions, 3 clock cycles for MUL instruction, and 6 clock cycles for DIV instruction respectively. Operand forwarding is used in the pipeline. What is the number of clock cycles needed to execute the following sequence of instructions? Instruction Meaning of instruction I0 : MUL R2, R0, R1 R2← R0 * R1 I1 : DIV R5, R3, R4 R5 ← R3 / R4 I2 : ADD R2, R5, R2 R2 ← R5 + R2 I3 : SUB R5, R2, R6 R5 ← R2 – R6

In a town of 500 people, 285 read Hindu and 212 read Indian Express and 127 read Times of India, 20 read Hindu and Times of India and 29 read Hindu and Indian Express and 35 read Times of India and Indian express . 50 read no news paper . Then how many read only one paper ?
The following code segment is executed on a processor which allows only register operands in its instructions. Each instruction can have atmost two source operands and one destination operand. Assume that all variables are dead after this code segment. c = a + b; d = c * a; e = c + a; x = c * c; if (x > a) {     y = a * a; } else {      d = d * d;      e = e * e; } Suppose the instruction set architecture of the processor has only two registers. The only allowed compiler optimization is code motion, which moves statements from one place to another while preserving correctness. What is the minimum number of spills to memory in the compiled code?
