5 The MIPS Instruction Formats All MIPS instructions are bits long The three instruction formats: R-type op 6 bits rs 5 bits rt 5 bits rd 5 bits shamt 5 5 THUMB Instruction Set This chapter describes the THUMB instruction set. Format Summary 5-2 Opcode Summary 5-3 5. Format : move shifted
The assembler formats for the instruction and the architecture level at which the instruction was originally defined are given in the Format field. MIPS32. The assembler format is shown with literal parts of the assembler instruction printed in uppercase characters.
Figure 6: MIPS “I” instruction format used for the extension instruction. The opcode that identifies the instruction must be unique or it will alias onto an existing instruction. There are three instruction formats in the MIPS I and MIPS II instruction set architectures supported by M2V: “I,” “R,” and “J”.
MIPS Instruction Reference. This is a description of the MIPS instruction set, their meanings, syntax, semantics, and bit encodings. The syntax given for each instruction refers to the assembly language syntax supported by the MIPS assembler.

q MIPS uses three-address instructions for data manipulation. – Each ALU instruction contains a destination and two sources. – Some MIPS instructions allow you to specify a signed constant, or “immediate” value, for the second source instead of a register.
A.1 Instruction Encodings and Instruction Classes. A.2 Instruction Bit Encoding Tables. A.3 Floating Point Unit Instruction Format Encodings. MIPS32. The assembler format is shown with literal parts of the assembler instruction printed in uppercase characters. The variable parts, the
Machine Language: R Format. • Instructions, like registers and words of data, are also 32 bits long – Example: add $t0, $s1, $s2 – registers In MIPS, data must be in registers to perform arithmetic. MIPS register $zero always equals 0. Register $at is reserved for the assembler to handle large constants.
