RELIANCE MD-D4002B Control processor

The computer can only complete the operation, while the controller is used to control the work of the whole CPU.
1. Instruction controller
Instruction controller is a very important part of the controller, it needs to complete fetch instruction, analyze instruction and other operations, and then give to the execution unit (ALU or FPU) to execute, but also form the address of the next instruction.
2. Timing controller
The function of a timing controller is to provide a control signal for each instruction in chronological order. The timing controller includes a clock generator and a frequency doubling definition unit. The clock generator sends out a very stable pulse signal from the quartz crystal oscillator, which is the main frequency of the CPU. The frequency doubling definition unit defines the CPU frequency as several times the memory frequency (bus frequency).
3. Bus controller
The bus controller is mainly used to control the internal and external buses of the CPU, including the address bus, data bus, control bus, and so on.
4. Interrupt the controller
The interrupt controller is used to control a variety of interrupt requests, queue the interrupt requests according to the priority, and send them to the CPU for processing one by one.
