In contrast, data stored in Dynamic Random Access Memory (DRAM) needs to be periodically updated. However, when the power supply is stopped, the data stored in the SRAM is lost (referred to as a volatile memory), unlike a ROM or a flash memory which can store data after power is turned off.

The English of SPI is known as SERIAL PERIPHERAL INTERFACE, and as the name implies, is a serial peripheral interface. SPI is a synchronous serial communication interface specification, and is mainly applied to short-distance communication in embedded systems.

A universal asynchronous receiver transmitter (Universal Asynchronous Receiver/transmitter, commonly referred to as UART) is an asynchronous receiver transmitter that is part of the computer hardware that transmits data via serial communication. It performs parallel-to-serial data conversion at the transmitting end and serial-to-parallel data conversion at the receiving end. It is versatile in that the parameters transmission speed, data speed, etc. are configurable. UARTs are commonly used in connection with other communication interfaces (e.g., EIARS-232).

The I2C bus is a simple, bi-directional two-wire synchronous serial bus. It requires only two wires to transfer information between devices connected to the bus. The master device is used to initiate the bus transfer of data and generate a clock to open the transfer device, where any addressed device is considered a slave device. If the host computer is to send data to the slave device, the host computer firstly addresses the slave device, then actively sends the data to the slave device, and finally the host computer terminates the data transmission; if the host is to receive data from the slave, the slave is addressed by the master first, then the host receives data sent by the slave, and finally the host terminates the receiving process. In this case, the host is responsible for generating the timing clock and terminating the data transfer.

The functional module can also be regarded as an intermediate node module, and can be determined according to actual service requirements, for example, an encryption and decryption data processing module for performing encryption and decryption operations on data; the user may configure the function module by using, if the function module is an external module such as SPI/UART/I2C, an intermediate node module configuration parameter for expressing an input/output data format for the function module, for example, a byte format of I2C, an address format of a bit, etc. may be used as the intermediate node module configuration parameter, and writing the intermediate node module configuration parameter table for the virtual device, and inserting the function module identifier of the virtual device in the virtual device pipeline configuration table.
