Step by step
Solved in 2 steps with 4 images
- _____ is a CPU design technique in which instruction execution is divided into multiple stages and different instructions can execute in different stages simultaneously.Computer Architecture (Already submit this question, but I think I got wrong solution) Consider a computer that has a number of registers such that the three registers R0 =1500, R1 = 4500, and R2 = 1000 Show the effective address of memory and the registers’ contents in each of the following instructions 1. ADD (R1), R2 2. MOVE 500(R0), R2 3. ADD (40), R1 4. SUBTRACT (5000), R2 5. ADD #30, R2Computer Science Based on the following equation, write the programs (using three, two and one address instructions), and compare them on the basis of memory access, and the number of instructions. Z = (a − b)/ c + (d × e)
- To define an Instruction Length, we look at the following: Identify two constraints imposed by the design that increase the need for, or the size of, the manual and explain how you overcame them.For a program execution, Step 1 is completed in the below diagram by filling the required CPU registers (PC, AC and IR). Fill the same registers for remaining steps. The contents of memory are shown hexadecimal and the list of opcodes is as under:A computer has a 256K word addressable memory Module with 16 bits per word. The instruction set consists of 166 different instructions. 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. Based on the above, answer the following questions: a. How many bits are there in the main memory? (Represent it in power of 2) b. How many bits are needed for the opcode? c. How many bits are left for the address part of the instruction? d. How many additional instructions can be added to the existing 166 without affecting the assigned size of the opcode part? Justify.
- Write all the possible Opcodes of Memory-reference instruction in basic computer (write Opcodes in binary ).Define pipelining in terms of increasing the speed of a processor, and then determine how many cycles it would take to run five instructions if each part of the machine required the same amount of time. In the absence of pipelining With pipelining, you may do (a), (b), (c), and (d), respectively.The architecture of a CPU may consist of a universal register, a singular accumulator, or a stack. Each has benefits and drawbacks. Your response could be correct or incorrect.
