MIPS Microprocessor Manual
GPR[rd] _ GPR[rs] + GPR[rt]
Notes:
When we want to explain something to a human, we take a complete different approach, a approach that is closer to how we think.
For example, to describe the behavior of a microprocessor to a programmer, we don’t tell a person how the program counter is updated on every clock cycle, we say when the processor is executing a particular instruction, this is everything it does.
