Instruction set
The MIPS32 instruction set can be broadly divided into the following categories:
| Category | Description |
|---|---|
Data processing | Instructions that perform arithmetic and logical operations on data stored in registers or memory |
Control flow | Instructions that allow the processor to change the flow of execution in a program |
Memory access | Instructions that allow the processor to read from and write to memory |
Floating point | Instructions that support the use of floating point numbers in programs |
Multimedia | Instructions that are optimized for processing multimedia data, such as audio and video |
Overall, the MIPS32 instruction set includes a wide range of instructions designed to support a variety of different types of applications and workloads.
Data processing
| Instruction | Description |
|---|---|
| Add two values and store the result in a register |
| Subtract one value from another and store the result in a register |
| Multiply two values and store the result in a register |
| Divide one value by another and store the result in a register |
| Perform a bitwise AND operation on two values and store the result in a register |
| Perform a bitwise OR operation on two values and store the result in a register |
| Perform a bitwise XOR operation on two values and store the result in a register |
| Perform a bitwise NOR operation on two values and store the result in a register |
These instructions allow the processor to perform various types of arithmetic and logical operations on data stored in registers or memory. They are a fundamental part of the MIPS32 instruction set and are used extensively in many types of programs.
Control flow
| Instruction | Description |
|---|---|
| Jump to a new address in the program |
| Jump to a new address and store the return address in a register |
| Branch to a new address if two values are equal |
| Branch to a new address if two values are not equal |
| Trigger a system call or exception |
These instructions allow the processor to change the flow of execution in a program. They can be used to implement branching, looping, and other control structures, as well as to handle exceptions and interrupts. They are an important part of the MIPS32 instruction set and are used extensively in many types of programs.
Memory access
| Instruction | Description |
|---|---|
| Load a word (4 bytes) from memory into a register |
| Store a word (4 bytes) from a register to memory |
| Load a byte from memory into a register |
| Store a byte from a register to memory |
These instructions allow the processor to read from and write to memory. They are used to load data from memory into registers for processing, and to store the results of processing back to memory. They are an important part of the MIPS32 instruction set and are used extensively in many types of programs.
Floating point
| Instruction | Description |
|---|---|
| Add two floating point values and store the result in a register |
| Subtract one floating point value from another and store the result in a register |
| Multiply two floating point values and store the result in a register |
| Divide one floating point value by another and store the result in a register |
| Convert an integer value to a floating point value and store the result in a register |
| Convert a floating point value to an integer value and store the result in a register |
These instructions allow the processor to perform various types of arithmetic operations on floating point numbers, as well as to convert between floating point and integer formats. They are an important part of the MIPS32 instruction set and are used extensively in many types of programs that require the use of floating point numbers.
Multimedia
| Instruction | Description |
|---|---|
| Pack 8-bit integers into a single register |
| Unpack 8-bit integers from a single register |
| Perform an addition operation on packed data |
| Perform a multiplication operation on packed data |
These instructions are optimized for processing multimedia data, such as audio and video. They allow the processor to perform operations on packed data (e.g. packed 8-bit integers) and to perform SIMD (Single Instruction, Multiple Data) operations. They are an important part of the MIPS32 instruction set and are used extensively in many types of programs that require efficient processing of multimedia data.
