Microcode is a layer of low-level instructions stored in a computer's firmware that controls the operations of the processor. Its purpose is to translate complex instructions from higher-level programming languages into simpler operations that the processor can understand and execute efficiently. This helps improve the performance and flexibility of the processor while allowing for updates to be made without needing to modify the actual hardware.

What is the groups of instructions that accomplish functional operations?
A group of instructions that accomplish functional operations is typically referred to as a function or method. These functions contain a set of statements or commands that perform a specific task or operation within a program. By organizing code into functions, developers can modularize their code, improve readability, and promote reusability.
What is the purpose of a bycicle?
The purpose of a bicycle is to help people get around.
What is the purpose of the planets other than the Earth?
They have no particular purpose
What is the purpose of annexure?
The purpose of annexure is to acquisition and incorporate an entity.
What is the purpose of a mankini?
the purpose of a mankini is so you can have a brothel with your pet hamster
Instructions which are permanently built into the processor chip are called?
Microcode.
Which CPU component contains microcode?
EEPROM or PROM contains the microcode
Are instructions which are permanently built into the processor chip called microcode?
Called Microcode
Which language computer can understand directly?
People will say machine code but that actual truth is microcode. Microcode is actually a level lower than machine code, providing a platform from which machine code can be executed on. Microcode is the actual language of the hardware.
How many bits for a control word of microcode?
Some CPUs have a "wide" microcode word of more than 56 bits. Some very simple CPUs, such as Viktor's Amazing 4-bit Processor, have a "narrow" microcode word of less than 8 bits.
What is the code used to program a computer?
binary and below that, microcode.
Programmers use instructions to program a PROM chip?
Microcode
WHAT part of the processor is responsible for directing actions performed by the processor?
When an instruction reaches a microprocessor it arrives at an internal block known as a "microcode sequencer" which is present in CISC architectures. This microcode sequencer then steps through a series of locations in the microcode ROM and issues control signals to the various registers, multiplexers, ALU, etc in the microprocessor. RISC architectures lack this microcode sequencer, but have a similar construct known as a microcode translator or interpreter. Because RISC machines must complete execution in a single clock cycle, there aren't any "steps" to cycle through. Remember that RISC instructions are inherently more simple than CISC instructions.
Instructions which are permanently built into the processor chip are called what?
the correct answer is Microcode
Programming in High Level Language?
No. It's machine code and microcode.
What is Micro Program Control Unit?
A micro program control unit is the underlying hardware that executes microcode. In turn, microcode is the code that is executed in order to process instructions, or code. In modern processors, an instruction is fetched from some area of memory (one or more bytes of memory), and is then parsed and executed by microcode. Microcode runs on the various gates and transistors that comprise the CPU. One might consider microcode to be the operating system ("OS") of the CPU, just as Windows, Linux, Android, etc, is consider the OS of the computer. Microcode allows a standard chipset to be programmed in different ways, altering its behavior completely. Optimizing microcode results in certain operations taking less or more time, allowing the same basic chip hardware to be specialized for certain types of tasks, such as favoring mathematical calculations or memory processing. Intel and AMD both offer "IBM-compatible" processors that expose the same set of instructions, but their microcode is different and reflects different interests in processing. Different iterations of the same chipset can be released that offer different characteristics without modifying the actual hardware. Furthermore, hardware-based designs (e.g. circuit programming) is relatively difficult and error-prone as compared to microcode programming. A mistake in microcode can be corrected simply by altering the code, while a mistake in a hardware design might require significant time and cost redesigning the entire circuit.
Advantages and disadvantages of microcode and machine language?
Microcode allows for easier implementation of complex instructions but can introduce additional overhead. Machine language directly corresponds to the hardware for faster execution but is more challenging to program and understand.
