State in brief about the pseudo instruction

A pseudo instruction isn't a real instruction. CPU can't execute it. It often requires a complex architectural operation and if it was an actual instruction, it would be a complex (CISC) instruction. In other cases, a pseudo instruction may require a simple architectural operation and would be one simple RISC instruction. Why one would have it as a pseudo instruction is then that its syntax is more convenient, which implies easier to learn and use, as in case of "MOVE" and "CLEAR" pseudo instructions asked in Homework I. Several MIPS pseudo instructions are given in the textbook, for example BLT (Branch Less Than) and LI (Load Immediate). Pseudo instructions used by the programmer are converted to real instructions by the assembler.
