There аre 6 prоblems fоr а tоtаl of 108 points. You must write your solutions on a blank sheet of paper OR a blank document if using a tablet. Work will not be submitted using this Canvas Quiz. You must label your solution with the number of the question and part to which you are responding. You must upload only one file with all of your solutions attached as screenshots. Read each question very carefully. In order to receive full credit for each portion of the test, you must: Show legible and logical (relevant) justification which supports your final answer. Use complete and correct mathematical notation. You have 75 minutes to complete the entire test, +15 minutes to complete the submission. Notation:
LC 2200 ISA with аn аdditiоnаl LEA and BGT instructiоn Mnemоnic Example Opcode (Binary) Action Register Transfer Language add add $v0, $a0, $a1 0000 Add contents of reg Y with contents of reg Z, store results in reg X. RTL: $v0 ← $a0 + $a1 nand nand $v0, $a0, $a1 0001 Nand contents of reg Y with contents of reg Z, store results in reg X. RTL: $v0 ← ~($a0 && $a1) addi addi $v0, $a0, 25 0010 Add Immediate value to the contents of reg Y and store the result in reg X. RTL: $v0←$a0+25 lw lw $v0, 0x42($fp) 0011 Load reg X from memory. The memory address is formed by adding OFFSET to the contents of reg Y. RTL: $v0 ← MEM[$fp + 0x42] sw sw $a0, 0x42($fp) 0100 Store reg X into memory. The memory address is formed by adding OFFSET to the contents of reg Y. RTL: MEM[$fp + 0x42] ← $a0 beq beq $a0, $a1, done 0101 Compare the contents of reg X and reg Y. If they are the same, then branch to the address PC+1+OFFSET, where PC is the address of the beq instruction. RTL: if($a0 == $a1) PC ← PC+1+OFFSET jalr jalr $at, $ra 0110 First store PC+1 into reg Y, where PC is the address of the jalr instruction. Then branch to the address now contained in reg X. Note that if reg X is the same as reg Y, the processor will first store PC+1 into that register, then end up branching to PC+1. RTL: $ra ← PC+1; PC ← $at Note that an unconditional jump can be realized using jalr $ra, $t0, and discarding the value stored in $t0 by the instruction. This is why there is no separate jump instruction in LC-2200. halt 0111 Halt the machine bgt bgt $a0, $a1, done 1000 Compare the contents of reg X and reg Y. If the value in reg X is greater than the value in reg Y, then branch to the address PC+1+OFFSET, where PC is the address of the bgt instruction. RTL: if($a0 > $a1) PC ← PC+1+OFFSET lea lea $a0, stack 1001 An address is computed by sign-extending bits [19:0] to 32 bits and adding this result to the incremented PC (address of instruction + 1). It then stores the computed address into register DR. RTL: $a0 = MEM[stack]
