THIS NEEDS TO BE DONE USING MIPS INSTRUCTIONS
Problem 3 For this problem, please write the MIPS instructions that implement a write onto the stack pointer. The stack pointer register $sp by convention points at the top item of the stack. The operating system sets the initial value of the stack. address Memory lower 335 $sp -> 876 556 -397 higher When stack is accessed (either get or store a value/variable), the stack pointer register should be updated. Let us assume we are storing the value of register $s0 on the stack. You need a couple of instructions to do this operation. need 2 destructons no tes ouly EE334 MIPS Instruction Set Reference Card OPCODE ARITHMETIC CORE INSTRUCTION SET MIPS /EMT/FT /FUNCT Ole) Reference Data FOR- NAME, MNEMONIC MAT OPERATION Branch On FP True beit iRTPeondO-PC4Brancdde (4) i Bsch On FP False belf niRIFPondPC-PC4BranchAddr4) 110- dis R LaRjaRn He-RR Divide Llsiged 4 R Lo-RinRint HRwR) (6 ib ad.
