Xiaobian to share with you where the io interface is located, I hope you read this article after the harvest, let us discuss it together!

The IO interface is located between the bus and the I/O device. The host memory is connected through the system bus, and the host and I/O device are connected through the system bus I/O interface, and then connected to the I/O device, rather than the I/O device directly connected to the system bus.

The io interface is located between the bus and I/O devices.

Host memory goes through the system bus. The host and I/O devices are connected through the system bus I/O interface and then connected to the I/O devices, rather than the I/O devices directly connected to the system bus.

Related Introduction:

I/O interface is the link between host and controlled object for information exchange. The host exchanges data with external devices through I/O interfaces. Most I/O interface circuits are programmable, that is, their operation mode can be controlled by programs. The interfaces commonly used in industrial control machines are:1, parallel interfaces, such as 8155 and 8255; 2, serial interfaces, such as 8251;3, direct data transmission interfaces, such as 8237;4, interrupt control interfaces, such as 8259; 5, timer/counter interfaces, such as 8253. In addition, since the computer can only receive digital quantities, and the measured parameters of the general continuous production process are mostly analog quantities, such as temperature, pressure, flow, liquid level, speed, voltage and current, etc., in order to realize computer control, analog quantities must also be converted into digital quantities, that is, A/D conversion.

After reading this article, I believe you have a certain understanding of where the io interface is located. If you want to know more about it, welcome to pay attention to the industry information channel. Thank you for reading!
