What addressing modes are available in DLX
Problem 1.7: Find the addressing modes of the below instructions Memory addressing mode Instruction MOV A, RO; MOV A, @RO; MOV A, #30H; MOV A, 30H; MOVA, @A+DPTR MOV C, A.O; MOV C, 31H; AJMP 3001H; MOV A, 70H;
a) What are the 5 addressing modes for MIPS? Provide an example of each type. b) Explain how the memory address is computed from immediate value of a jump () instruction c) Explain mult instruction with an example. Where the results will be stored, and how this results can be copied to Values registers?
For each of these addressing modes Indexed register For each Provide a motivated context in C well suited to its use. (hint: think about variable lifetime) Indicate whether the encoding of this addressing mode requires an extension word, and why.
ASSEMBLY: Identify which of the following addressing modes are illegal, explain why it is illegal. A) mov bl, [rbx][rbx] B) mov ebx, [cs] C) mov ah, [rbp][rbx] D) mov ax, [rbp*10] E) mov bx, [rax*8][rbp][-7] F) mov dx, [rbp*1][rax*8] G) mov r15, [VTable+rax][rcx] H) mov rbp, [rsp+rax] I) mov cl, [rdx][rax*8] J) mov ax, [ah][al]
4. Addressing modes (10 pts) There are many ways to get the address for the operands in an instruction. Explain the difference between these pairs of instructions by showing the contents of R5 after the commands: (assume: R4-0x2400, R6-23FE, R7-2) mov.w R4,R5 value 23FC 23FE Label Memory mov.w GR4,R5 address 0x23FC 0x23FD 0x23FE 0x23FF 0x2400 0x2401 0x2402 0x2403 0x2404 0x2405 data Start 4 A mov.w X, R5 7 D A 6 mov.w 2 (R6),R5 mov.w Start (R7),R!5

The basic pipeline for DLX has five stages: IF, ID, EX, MEM, and WB. Assuming all memory accesses take 1 clock cycle. a) What are the three types of pipeline hazards? b) What is the control (branch) hazard of an instruction pipeline? Provide three branch prediction alternatives to reduce branch hazards. c) What is the data forwarding scheme used to reduce the data hazard? d) Give all the forwarding paths of the five-stage DLX pipeline, including sources, destinations, and information...
