EEPROM or PROM contains the microcode
Many people would consider the central component of a computer to be the CPU, or Central Processing Unit.
The "Intel CPU ucode loading error" typically indicates a problem with loading the microcode updates for the Intel processor during system boot. This error may arise due to an outdated BIOS or firmware, missing microcode files, or incompatible hardware. To resolve it, ensure your BIOS is updated to the latest version and check for the correct microcode files in your operating system. Additionally, verifying hardware compatibility can help prevent this error from occurring.
A CPU contains a control unit and an arithmetic/logic unit

The GMCH
The instruction decoder is the part of the CPU that converts the bits stored in the instruction register into control signals need to control other parts of the processor. In CPUs that use microcode, the decoder converts microinstructions into the control signals.
Very few computers are capable of doing trigonometry directly in their ALU hardware. Instead trigonometry and other such difficult functions are performed by software subroutines in a mathematics library in main RAM. Most of the computers having instructions for such functions still don't do them directly in their ALU hardware, instead these instructions are performed by firmware routines in microcode in ROM inside the CPU.

The CPU, or "Cental Processing Unit"
Microprocessors work in microcode, not assembly language. Microcode processes machine instructions, which are often assembled from assembler languages; higher level languages often convert each line of code into multiple lines of assembler language before their ultimate compilation into an executable. The assembler language contains mnomonics that are used to translate each line of source code into a machine instruction. When those machine instructions are loaded in memory, the CPU will use microcode to interpret and execute those instructions. Barring some experimental CPUs that use non-traditional machine code (such as Sun's Java CPU), all production-class CPUs use machine instructions as their basis for software execution.
Microcode.
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.
