Folding operation logic unit

An operational logic unit that can perform fixed-point or floating-point arithmetic operations, shift operations, and logical operations, as well as address operations and conversions.

Folding register unit

A register component includes a general purpose register, a special purpose register and a control register.

General purpose registers can be divided into fixed-point numbers and floating-point numbers, which are used to store register operands and operation results in instructions.

The general purpose register is an important part of the central processing unit (CPU), and most instructions need to access the general purpose register. The width of the general purpose register determines the width of the data path inside the computer, and the number of its ports often affects the parallelism of the internal operation.

A special register is a register that is needed to perform some special operations.

Control registers are usually used to indicate the state of the machine's execution, or to hold some Pointers, including processing state registers, address translation directory base registers, privileged state registers, condition code registers, processing exception registers, and error detection registers.

Sometimes, there are some caches in the central processor, used to temporarily store some data instructions, the larger the cache, the faster the CPU operation speed, the current market of high-end central processors have about 2M of the second-level cache, high-end central processor has about 4M of the second-level cache.
