Study Notes
- MIPS register set includes $0-$31, each with a specific usage such as storing constants, procedure return values, arguments, temporaries, saved variables, and more.
- Registers are denoted with a dollar sign ($) before their name, with $0 holding the constant value 0, $s0-$s7 used for variables, and $t0-$t9 for intermediate values during computations.
- MIPS assembly instructions involve registers, where high-level code like "a = b + c;" is translated to assembly like "add $s0, $s1, $s2" for adding values in registers $s1 and $s2 and storing the result in $s0.
- The MIPS processor was developed in the early 80s at Stanford University as one of the first RISC processors, emphasizing simplicity and regularity in instruction format.
- RAM is compared to registers in terms of speed and size, with registers being significantly faster but limited in number compared to RAM's larger capacity.
