Briefly explain microprogram

Here we are discussing about the microprogram. Here we have disussed some important point about the microprogram.

Micro program is basically a microcode to program a microprocessor. The objective is to define how a microprocessor should function when it executes. It is a low level language typically consists of machine language instructions which are stored in ROM and in some cases it is stored in EPROM.

Basically  microprogram  is a set of elementary instructions in a  CISC. The microprogram resides in a separate high speed memory and  perform functions as a translation layer between the machine instructions and the circuit level of the computer. microprogram  enables the computer designer to create machine instructions without having to design electronic circuits. Writing microcode is called "microprogramming," and the microcode for a given computer is called a "microprogram."
RISC computers do not use microcode,  the reason why RISC compilers generate more instructions than CISC compilers.
