MIPS Registers and MIPS Instruction Set
MIPS registers based this tutorial will be helpful in understanding the concepts of MIPS registers in computer architecture. In this MIPS registers based processor register tutorial we will learn about instrumentation segmentation, processor registers, MIPS instruction and MIPS instruction set, its architecture.

What is Register ?
Register is a sequential circuit and used to store the data. Registers consist of various flip flops. Register are also used to transfer data and instructions that are used by the Central Processing Unit.
There are different types of Registers those are used for different purpose.
Central processing units used processor registers some of the most common types of registers used are AC or accumulator, Data Register, Memory Address register, Program counter registers. These registers are also known as special purpose processor registers
What are MIPS Registers ?
In MIPS registers the full form of MIPS is Million Instructions Per Second. MIPS registers are the special type of registers which are basically designed to optimize segmentation in control units and to facilitate automatic generation of machine code by compilers.
Control unit implementation technique that allows instructions to be processed in series, dividing them into phases. With a single instruction execution channel it is possible to keep executing several instructions simultaneously, each one in a different phase.
Key Points– MIPS is modular architecture that supports up to four coprocessors.
What is MIPS Instruction Set ?
The MIPS instruction set is quite similar to what one finds in many modern processors. MIPS is a set of instructions load / store (load / storage), this means that the data elements must be copied or loaded ( load ) in registers before processing them; operation results also go to registers and must be explicitly copied back to memory via store operations(storage) separate.
MIPS instruction life cycle follows 5 stage classic RISC pipelining. These 5 phases of MIPS instructions are instruction fetch (IF), instruction decode(ID), Operand Fetch(OF), Instruction Execute (IE) and Write Back( WB).
Therefore in order to understand and be able to use MIPS registers it is necessary to know about in-memory data storage schemes, functions of loading and storing instructions, types of operations allowed on data elements that are kept in registers, and some other loose aspects that allow efficient programming.
Some important features of MIPS registers are as follows
- MIPS is RISC (computer with reduced instruction repertoire).
- Before being used in an arithmetic instruction, all data must be previously loaded into a general-purpose register.
- Instruction size is 32 bits.
MIPS Registers and Memory
The mips registers have a memory unit with up to 2 30 words (2 32 bytes), an Integer Data Processing Unit (EIU), a Floating Point Unit (FPU) ) and a divert and memory unit (TMU, Trap & Memory Unit
The EIU interprets and executes the most basic MIPS instructions (which we will begin to study) and has 32 bits general-purpose registers, each 32 bits wide therefore it can address the contents of a memory location (2 32 addressable bytes).
The Arithmetic Logic Unit (ALU) executes the addition (subtraction), subtraction (subtraction), and logical (logical) instructions. A separate arithmetic unit is devoted to mutliplication and division instructions, the results of which are placed in two special registers, called “Hi” and “Lo,” from which they can be moved to general-purpose registers.
A 32-bit data item stored in a register or memory location (with an address divisible by 4) is known as a word. For now, suppose a word retains a statement or a signed integer, though later you will see that it can also retain an unsigned integer, floating point number, or ASCII character string.
Since words in mips registers are stored in byte addressable memory, a convention is required to establish which end of the word appears in the first byte (the one with the lowest memory address). Of the two possible conventions in this regard, MIPS uses the big-endian (highest ending) schema, where the most significant end appears first.
The hardware principle that relates size to speed suggests that memory should be slower than records because the size of the recordset is less than that of memory. Access to data is faster if the data is in records.
And data is most useful when it is in registers because an arithmetic statement is applied to two registers, while memory accesses only manipulate one data.
Conclusion and Summary
In conclusion, the data in the records in mips registers takes less time and has a higher productivity than the data in memory. To increase performance, MIPS compilers must use the logs efficiently.
