The following code is to be scheduled and executed on a two-slot VLIW machine with the goal of achieving a minimum number of cycles. A bundle in this architecture has two instructions. The first of these instructions can be only an ALU or branch instruction, whereas the second one can be only a load or sto instruction. You are allowed to reorder independent instructions and change the offset of addressing (if needed). You are not allowed to combine instruction loop: Iw r2, 0(r1) Iw r4, 4(r1) add r2, r2, r8 add r4, r4, r8 sw r2, 4(r1) sw r4, 0(r1) sub r1, r1, -4 bne r1, $zero, loop Show the instruction bundles issued by the VLIW machine for the above code. Please write one instruction bundle per line.

Assign the register numbers for all the variables. You are encouraged to refer the MIPS assembly registers. (2) Select appropriate assembly instructions for arithmetic operations and if/else statements. (3) Once you have the assembly instructions for arithmetic operations and if/else statement, pair up these instructions with beq/bne and j instructions. If the condition has equality comparison, you may need to slt instruction. Using slt instruction, you can set a temporary value (t) to 1 and branch to the next instruction with beq/bne instruction. (4) Finally, add the comments for each instruction line to clarify. Assume the integer variables g and h are in registers $s2 and $s3, respectively. if (g > h) g = g + h;else g = g – h; if (g >= h) g = g + 1;else h = h – 1; if (g <= h) g = 0;else h = 0;

The inclusion of a "backup" instruction in a design for an instruction set is what is meant by the term "orthogonality." This "backup" instruction may be substituted for any other instruction that accomplishes the same goal. You now have the responsibility of proving or disproving my hypothesis.
You are given the following instruction: ADD AX, [10h] You are provided the following data: DS = AB12h ; SS = 2567h ; CS= 29C1h Find the effective address location for the given instruction.
The class I'm taking is assembly programming. I am completely stuck .Thank you so much for your help! Any help is greatly appreciated.
All rotate and shift instructions operate with carry flag directly. * True False AL=7EH, BL=82H after execute ADD AL. BL the flags will be O CF=AF=ZF=1 CF=AF=don't affect, ZF=1 CF=AF=1, ZF=0 CF=AF=ZF=0 The instruction AND AL.FFH is equivalent to XOR AL,FFH XOR AL,00H MOV AL,AL XOR AL ALH O None of the above
Orthogonality means that an instruction set has a "backup" instruction that can be used instead of any other instruction that does the same thing. It's up to you to prove or disprove what I think.

We want to design a new K-format instruction for a branch-equal-immediate. A: What information would need to be encoded in a beq R2, 7, loop instruction? B: Why can't we have a beq R2, 7, loop instruction? and C: How could we fix this? Hint: think about the instruction encodings and what we need to encode such an instruction.

This question assumes the machine architecture at the right. Note the stack pointer register, SP, is not part of the register file. SEL is a multiplexor used to select one of the inputs to the ALU. Assume memory addresses require only one memory cycle to fetch or store (unlike the 68000). MAR Register File (RO-RI5) MDR Show the machine code control IR constants sequence of an instruction that will set a block of from 1 to 127 memory locations to zero. The size of the block is in RO and the address of the block is in R1. Assume the instruction fetch sequence is the same as in Question 4 and start with the next step. R0 and R1 can change in the execution of the sequence. SEL PC SP ALU TEMP Status
