Suppose we have two implementations of the same instruction set architecture. Computer A has a clock cycle time of 200 ps and a CPI of 2 for some program, and computer B has a clock cycle time of 500 ps and a CPI of 1.25 for the same program. Which computer is faster for this program, and by how much?

For example, suppose an instruction is not accepted and VA page 30 is generated. For the following use cases, a TLB controlled by software might be preferable than one handled by hardware:

I need the answer as soon as possible

Using the diagram, what would be the paths.

Suppose you are developing a processor with an execution time of 960 ns, CPI of 1.61, and clock rate of 3 GHz. If the execution time is reduced by an additional 20% without affecting to the CPI and with a clock rate of 4 GHz, determine the number of instructions.

B. For the following 8085 assemble code, calculate the total execution time 0100: LXI 0103: MVI C,0 0105: NOP 0106: NOP 0107: DER C D,1000H 0108: JNZ 0105H 010A: MOV A,M 010B: OUT 05H SKIP : C. what is the single instruction equivalent to the following code: XOR DX,DX TEST AX,8000H JZ NOT Total execution time = SKIP DX

Suppose that you have a computer with a memory unit of 24 bits per word. In this computer, the assembly program's instruction set consists of 198 different operations. All instructions have an operation code part (opcode) and an address part (allowing for only one address). Each instruction is stored in one word of memory. a. How many bits are needed for the opcode? b. How many bits are left for the address part of the instruction? c. How many additional instructions could be added to this instruction set without exceeding the assigned number of bits? Discuss and show your calculations.

Consider two computers, P1 and P2, of the same instruction set (ISA). We have a program of 7.5x10° instructions and we want to run this program on P1 and P2. The P1 computer is a 5 GHz machine with CPI of 0.8. The P2 computer is a 6 GHz machine with CPI of 1.2. What is the CPU time of P1 computer to run this program?

Consider two computers, P1 and P2, of the same instruction set (ISA). We have a program of 7.5x10⁹ instructions and we want to run this program on P1 and P2. The P1 computer is a 5 GHz machine with CPI of 0.8. The P2 computer is a 6 GHz machine with CPI of 1.2. How many times that computer is faster than another?

Consider two different implementations, 1 and 12, of the same instruction set. There are three classes of instructions (A, B, and C) in the instruction set. I1 has a clock rate of 6GHZ, and 12 has a clock rate of 3GHZ. The average number of cycles for each instruction class on 1 and 12 is given in the following table: CPI on 12 C1 Usage C2 Usage Class CPI on 11 C3 Usage A 2. 40% 40% 50% 40% 20% 25% 5 20% 40% 25% The table also contains a summary of average proportion of instruction classes generated by three different compilers. C1 is a compiler produced by the makers of 1, C2 is produced by the makers of 12, and the other compiler is a third-party product. Assume that each compiler uses the same number of instructions for a given program but that the instruction mix is as described in the table. Using C1 on both 1 and 12, how much faster can the makers of 1 claim 1 is compared to 12? Using C2, how much faster can the makers of 12 claim that 12 is compared to 1?
