Q. Explain Sample Instruction Format of MIPS instruction?
All MIPS instructions are of same size and are 32 bits long. MIPS designers chose to keep all instructions of same length thus requiring various kinds of instruction formats for different kinds of instructions. For illustration R-type (register) or R-format is used for arithmetic instructions (Figure below). A second type ofinstruction format is known as i-type or i-format and is used by data transfer instructions.

Instruction format of I-type instructions is given below:
