RV32I instruction

a)

You have fetched an RV32I machine language instruction, and you are to decode the instruction into its corresponding assembly language instruction. The machine language instruction (in hexadecimal) is: 00 25 0D 93

Identify the corresponding assembly language instruction. Note that numbers in the assembly language instruction are given in base 10 (decimal) and the an "x" placed in front of a number identifies a register number. (x12 => register 12)

A. ORI x10, x27, 2

B. ANDI x10, x27, 2

C. XORI x27, x10, 2

D. ADDI x27, x10, 2

E. LB x27, x10, 2

b)

You have fetched an RV32I machine language instruction, and you are to decode the instruction into its corresponding assembly language instruction. The machine language instruction (in hexadecimal) is: 00 83 48 63

Identify the corresponding assembly language instruction. Note that numbers in the assembly language instruction are given in base 10 (decimal) and the an "x" placed in front of a number identifies a register number. (x12 => register 12)

A. LB x16, 8(x6)

B. LW x16, 8(x6)

C. BLT x6, x8, 8

D. BEQ x8, x6, 8

E. BGE x8, x6, 8

c)
