    However, since MIPS instructions are 32 bits, we can't do that. In theory, you only need 30 bits to specify the address of an instruction in memory. However, MIPS uses 6 bits for the opcode, so there's still not enough bits to do true direct addressing. Instead, we can do pseudo-direct addressing. This occurs in j instructions.

    Instructions per second (IPS) is a measure of a computer's processor speed. For CISC computers different instructions take different amounts of time, so the value measured depends on the instruction mix; even for comparing processors in the same family the IPS measurement can be problematic.
