MIPS Reference Sheet TA: Kevin Liston. There are a few special notations outlined here for reference. Notation: Meaning: Example {X, Y} Concatenate the bits of X and Y together. {10, 11, 011} = 1011011: X × Y: Instruction Formats. There are 3 main instruction formats in MIPS. The fields in each type are laid out in such a way that the same The MIPS uses 32-bit addresses, but only allows 26 bits to specify an offset in the jump instruction. The 26-bit target is extended to 28 bits by adding two 0's on the right. This works because all MIPS instructions are 32-bits, and must begin at a word boundary (an address which is a multiple of 4). Such an address always ends in 00. Immediate Type ( I - Type ) I - type instruction format is includes with an immediate operand, branch instructions, and load & store instructions. Immediate type is to converted into machine code words . All memory in the MIPS accesses are handle by the main processor. So co - process of load and store also include in this category. 3.Two Address Instructions - This is common in commercial computers. Here two addresses can be specified in the instruction. Unlike earlier in one address instruction, the result was stored in the accumulator, here the result can be stored at different locations rather than just accumulators, but require more number of bit to represent address. What are the three instruction formats of MIPS processors? All instructions in the MIPS R2000 Architecture are 32 bits in length. There are three different instruction formats: R-Type instructions, I-Type instructions, and J-Type instructions. What are the 3 types of instructions? A basic computer has three instruction code formats which are: Instruction Format MIPS instructions are encoded in binary, as 32-bit instruction words , called machine code . The layout of an instruction is called the instruction format. Only 3 different formats exist.

On the greensheet, you can see many instructions. Scrolling down on the greensheet we can a table for all of the basic instruction formats. Taking a look at the I format, w
