Differences between Classification of Wire Harness Machining Interface

Classification of wiring harness processing interfaces: I/O interface chips: most of the chips are integrated circuits, and different parameters and commands can be input through the CPU, and control the related I/O circuit and some simple peripheral equipment to carry out the related operation. Common interface chips include: interrupt controller, parallel interface, counter, DMA controller, etc.; I/O interface control card: the control card is mainly composed of multiple integrated circuits according to a certain logic to form a component, or it is directly on the same motherboard as the CPU, or it can be a plug-in inserted on the bus slot of the system; The difference between the classification of wire harness processing interfaces: speed mismatch: the working speed of I/O equipment is much slower than that of CPU, and due to different types, the speed difference between them is also very large; Timing mismatch: each I/O device has its own timing control circuit, which transmits data at its own speed and cannot be unified with the CPU timing.
