Computer architecture using Mars assembly language.

please write the comments as well

Provide the type, assembly language instruction, and binary representation of instruction described by the following MIPS fields:

op=0, rs=3, rt=2, rd=3, shamt=0, funct=34

Answer 1

The MIPS instruction is an R-type SUB operation with assembly language instruction SUB $3, $3, $2, and binary representation 000000 00011 00010 00011 00000 100010.

Step-by-step explanation:

The student is asking about a specific MIPS assembly language instruction. Given the fields, the instruction type is R-type, as the operation code (op) is 0. The MIPS instruction is the subtraction (SUB) operation, which computes the difference of the contents of two registers and stores the result in a third register. The assembly language instruction is SUB $3, $3, $2, where $3 is the destination register (rd), $3 is the first source register (rs), and $2 is the second source register (rt). The binary representation for this instruction would be 000000 00011 00010 00011 00000 100010, composed of the concatenation of the op (6 bits), rs (5 bits), rt (5 bits), rd (5 bits), shamt (5 bits), and funct (6 bits) fields.
