How do the instruction encodings of ARM processors and MIPS processors differ?
What will be an ideal response?
Both the ARM and MIPS processors have classic RISC single?word 32?bit instructions. The fundamental
difference lies in the number of addressable registers. ARM processors have 16, whereas MIPS has 32. Halving
the number of registers saves three bits. ARM processors use these extra bits to provide a conditional execution
field for all instructions. Two other differences are that ARM processors have a smaller literal field (and the
literal is an 8?bit value scaled by a 4?bit ‘exponent’) and the ARM has some 4?register instructions, for example
those that perform a shift on the second operand.
