Problem 1. Write the machine code for the following assembly instructions. You will be able to find the opcodes for MIPS instructions online. Give your answers in hexadecimal R-Type rd shamt funct 5 bits 5 bits rt op 6 bits rs 5 bits 5 bits 6 bits I-Type op rs rt imm 6 bits 5 bits 5 bits 16 bits J-Type addr a) addi r10, r5,12 b) sub r3, r4, r7 c) Iw r1, 10(r2) d) beq r1, r4, L3 # the L3 label is at memory address 0x0050108C # the beq instruction is at memory address 0x00501028
