Data buffering: Since the rate of the I/O device is low and the rate of the CPU and memory is high, the -buffer must be set in the controller. At output time, this buffer is used to temporarily store the data transmitted from the host at high speed

The data in the buffer is then transferred to the I/0 device at the rate that the I/0 device has; During input, the buffer is used to temporarily store the data sent from the I/O device until the -batch data is received and then

Transfer data from the buffer to the host at high speed. Error control: The device controller is also responsible for error detection of the data transmitted by the I/O device. If an error is found in the transmission, it is usually an error

The error detection code is set and reported to the CPU, so the CPU invalidates the data sent this time and re-transmits it. In this way, the accuracy of data input can be minimized.

Data exchange: This refers to the realization of data exchange between the CPU and the controller, and between the controller and the device. For the former, data is written to the controller or from the controller in parallel by the CPU through the data bus

Read data in parallel; In the latter case, the device inputs data to the controller, or from the controller to the device.
