Write operations occur in the first half of the clock cycle and reads occur in the second half of the clock cycle. The table below shows the pipelining diagram for three instructions. Inst/CC 1 2 3 4 5 6 Inst. 1 IF ID EXE MEM WB Stall Inst. 2 Inst. 3 7 8 IF ID EXE MEM WB IF ID EXE MEM WB Where CC stands for clock cycle, stalls are shown as empty rows, and forwarding is indicated between associated stages using an arrow. LDUR X0, [X0, #5] SUB X2, X0, XO SUB X3, X1, X2 ADD X3, X2, X3 ADD X4, X1, X3 a. First assume forwarding is not available, show a similar table for the following sequence of instructions and indicate stalls with empty rows. How many cycles are needed to execute the above sequence of instructions?

List the steps necessary to read a word from memory in the 4 × 3 memory circuit shown below. Please explain all steps

Scala programming

The program execution of Figure 1.4 is described in the text using six steps. Expand this description to show the use of the MAR and MBR.

BX=FFFF, after instruction INC BX is executed, CF ||

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

Convert the given hex value to its R-format MIPS instruction by completing the following table. The instruction and letters for registers must be in lower case. DO NOT TYPE DOLLAR SIGNS WITH REGISTERS. Hex Opcode (decimal) rs (decimal) rt (decimal) rd (decimal) funct (decimal) Instruction 02488822 O 18 16 17 34 sub s4 $$1 " $ to " LA

ASSEMBLY The JBE instruction is used when comparing unsigned integers. True False

Q: Compute the physical address for the specified operand in each of the following instructions. The register contents and variable are as follows: (CS)=0A00H, (DS)=0B00H, (SS)=0D00H, (SI)=OFFOH, (DI)=00BOH, (BP)=00EAH and (IP)=00O0H, LIST=00FOH, AX=4020H, BX=2500H. 1) Destination operand of the instruction MOV LIST [BP+DI] , AX 2) Source operand of the instruction MOV CL, [BX+200H] 3) Destination operand of the instruction MOV [DI+6400H] , DX 4) Source operand of the instruction MOV AL, [BP+SI-400H] 5) Destination operand of the instruction MOV [DI+SP] , AX 6) Source operand of the instruction MOV CL, [SP+200H] 7) Destination operand of the instruction MOV [BX+DI+6400H] , CX 8) Source operand of the instruction MOV AL , [BP- 0200H] 9) Destination operand of the instruction MOV [SI] , AX 10) Destination operand of the instruction MOV [BX][DI]+0400H,AL 11) Source operand of the instruction MOV AX, [BP+200H] 12) Source operand of the instruction MOV AL, [SI-0100H] 13) Destination operand…

A problem-solving procedure that requires executing one or more comparison and branch instructions is called a(n) __________.
