Microprogramming

Microprogramming: alternative method to generate control signals in a systematic and orderly manner. It is to strategically program the control unit of a processor at the level of operations. A control memory stores binary code sequences that properly trigger control signals that perform certain micro operations.

Microprogram: sequence of micro-instructions whose execution corresponds to a machine instruction.

  • For each machine instruction, there is a specific microprogram indicating all the micro-operations required for its execution.

  • Executing a microprogram therefore has the same effect as executing a machine instruction.

Architecture: Typical CISC setam instructions "condition codes", which requires runtime, in addition to the fact that programmers have an extra effort in remembering to examine them.

Difference between Microprogramming and Machine Language

Machine Language is also known as Assembly, which means exactly what is written. It is the way a CPU or a microcontroller uses to communicate with its peripherals (binary), governed by the microprogram.

The microcode is an instruction-level hardware layer involved in the implementation of the machine language of the processors. Resides in special memory, high speed and translates machine instructions into sequence of circuit-level operations.

Microcode is often called microprogramming and the microcode in the implementation of a particular processor is called microprogram.

Just as Assembly is different from Assembler:

  • Which is the compiler that converts Assembly to machine language.

Reference and more information:

  • I’m sorry, but I think the answer is a bit confusing, instead of pasting snippets of other sites I think it would be better if you make an answer with your words or try to connect the website snippets in a way that makes the answer clearer

  • I adjusted the answer with less technical details and explaining what microprogramming is, basically it is at the level of operations in a layer of low level next to machine language.
