Question

Compare and Contrast MIPS and ARMS using the 7 ISA dimensions

Answer 1

MIPS vs ARMS

MIPS and ARM are two different instruction set architectures in the family of RISC instruction set.

Although both the instruction sets have a fixed and same instruction size, ARM has only 16 registers while MIPS has 32 registers.

ARM has a high throughput and a great efficiency than MIPS because ARM processors support 64-bit data buses between the core and the caches.

In order to allow efficient context switching, MIPS architecture supports the implementation of multiple banks of registers. ARM provides only general purpose registers for arithmetic operations and all the other functions, but MIPS provides two separate registers to hold the results of multiply operation.

MIPS has no equivalent instruction to the ARM MOV instruction.

The MIPS ADD instruction normally generates an exception on overflow, so it is rarely used than in ARM.

All ARM data processing instructions set the ALU condition codes by default, but MIPS provides the SLT for comparison.

Summary :- In the world of microprocessors, MIPS and ARM do a great service on behalf of their instruction set architectures. MIPSis implemented primarily in embedded systems. But, at present, ARM has become much more popular in the industry than MIPS.
