A microprocessor has an increment memory direct instruction, which adds 1 to the value in a memory location. The instruction has five stages: fetch opcode(four bus clock cycles),fetch operand address (three cycles), fetch operand (three cycles) add 1 to operand (three cycles), and store operand (three cycles). a. By what amount (in percent) will the duration of the instruction increase if we have to insert two bus wait states in each memory read and memory write operation? b. repeat assuming that the increment operation takes 13 cycles instead of 3 cycles

In CPU design, draw the datapath for the sw instruction. Include ONLY the portions necessary to carry out the operations of this instruction.

Data operation stage is happening after the operand address calculation in the instruction cycle. Select one: O True O False

construct the program for our imaginary computer!   There must be made of at least 5 instructions   There should be at least 3 different types of instructions (write, move, decrement, add, or)

In this classification, instructions are executed independently of one another's data sources. a(n): A Multiple Data Multiple Instruction B Multiple Data Multiple Instruction C Single Data Individual Instruction D Simultaneous In

In the diagram below, the chip on the right hand side, the 74HCT138, is provided with address information from the microprocessor and then activates one of its output lines to select a memory bank.  The 74HCT138 is   A multiplexer A demultiplexer An encoder A decoder A comparator

The loop instructions transfer execution control to another point designated by the instruction pointer. (ip) O (ecx) + sign extended 8-bit displacement (ip) + sign extended 8-bit displacement O (ip) + unsigned 8-bit displacement O (ecx) + unsigned 8-bit displacement

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, R2

Question 6 Suppose you have a RISC machine with a 1.6 GHz clock (i.e., the clock ticks 1.6 billion times per second). This particular computer uses an instruction cache, a data cache, an operand fetch unit, and an operand store unit. The instruction set includes simple instructions with the following timings: set reg, immed 2 clock cycle 2 clock cycles 2 clock cycle 4 clock cycles 3 clock cycles loop label add reg, immed add reg, reg load reg, mem Assume that the following code franent is used to sum the element of a numeric array. If the initialization code has already executed (i.e. the SET instructions have already finished execution) how many array elements can be processed in 5 ms? Round your answer to the nearest integer. Recall that 1 ms = 0.001 seconds. Also assume that there are no physical memory limitations, implying that the array can be as large as desired. ri, e r2, MAX_SIZE ;initialize loop counter r3, @list initialize sum set set set initialize array pointer more: load…

In this case, every instruction gets its own data in a way that is completely separate from how the data of other instructions is obtained. We utilize: A Multiple Data/Instruction B Multiple Data/Instruction C Singular Data Single Inst D Singe Inst Multiple
