Description
The structure of F8621A CPU can be roughly divided into operation logic component, register component and control component. The so-called operation logic unit, F8621A is mainly able to carry out related logic operations, such as: can perform shift operation and logic operation, in addition to can also perform fixed point or floating point arithmetic operation and address operation and conversion command, is a kind of multifunctional operation unit. Registers are used to temporarily store instructions, data, and addresses. The control unit is mainly used to analyze the instruction and can send out the corresponding control signal.
Function description:
Controller F8621A refers to the main command device that changes the wiring of the main circuit or the control circuit and changes the resistance value in the circuit to control the motor’s start, speed regulation, braking and reverse. Controller F8621A is composed of program status register PSR, system status register SSR, program counter PC, instruction register, etc. As a “decision mechanism”, its main task is to issue commands, and plays the role of coordination and command of the whole computer system operation. The classification of control mainly includes two kinds, namely, combinatorial logic controller and microprogram controller. Both parts have their own advantages and disadvantages. The structure of combinatorial logic controller is relatively complex, but it has the advantage of fast speed. Microprogram controller is designed with simple structure, but in modifying one machine instruction function, it needs to reprogram the whole microprogram.
