What is FPGA chip

FPGA is called on -site programming door array, which is a programmable logic chip.Compared with a fixed functional integration circuit, FPGA can be programmed as needed to achieve different circuit functions and is widely used in the electronics industry.

Introduction to serial communication

Serial communication is a communication method that transmits data through serial interfaces. At present, most of the UART or USART serial protocols are used for communication.Serial communication is often used in the communication of electronic devices such as microcontroller, embedded system, and single -chip microcomputer.

Serial communication in FPGA chip

In FPGA chips, serial communication modules are often used in MCUs to communicate with external devices, such as data transmission and program burning through serial ports with PC or other devices.Commonly used FPGA chip brands include Xilinx, Altera, etc.

The role of serial communication in FPGA chip

The serial communication module in the FPGA chip provides a communication interface between MCU and external devices to facilitate data transmission and program burns.The serial communication module can realize functions such as different baud rates, different data digits, and puppet verification to meet the needs of different application scenarios.

Design of serial communication module in FPGA chips

The serial communication module design in the FPGA chip mainly includes the baud rate generator, sending and receiving buffer, and control logic.The Potter generator sets different Potter rates as required. Sending and receiving buffer is used to store data, while controlling the logic to realize the calculation of Potter rate, data receiving and receiving, and amazing verification.

Implementation of serial communication modules in FPGA chips

There are two ways to implement the serial communication module. One is to use the FPGA development board integration serial communication module; the other is to implement the serial communication module by self -designing through the HDL language.Based on the development of existing modules, the development time and workload can be greatly reduced, and self -design can be customized according to actual needs.


Common serial communication protocols

Common serial communication protocols include UART, USART, SPI, I2C, etc.UART and USART are the two most commonly used communication protocols. Among them, UART is asynchronous transmission, and USART supports synchronization and asynchronous transmission.SPI and I2C communication methods are more complicated, but the speed is faster, and it can communicate with multiple devices at the same time.

Candidate communication in the FPGA chip implementation should be paid attention to

When implementing the serial communication module in the FPGA chip, you need to pay attention to the issue of timing and avoid data conflict.At the same time, we must also pay attention to the selection of serial communication protocols and the settings of baud rates to ensure that the communication between the equipment is running normally.

The serial communication development board commonly used in FPGA chips

The serial communication development boards commonly used in FPGA chips include Xilinx SP601, Xilinx Spartan-3E development board, Altera DE2 development board, etc.Most of these development boards integrate serial communication modules to facilitate developers for development and debugging.


The role of serial communication in actual application

Candidate communication plays an important role in practical applications.For example, in a single -chip microcomputer, you can communicate with the PC through the serial port, and you can perform data transmission, program debugging, and burning; in the embedded device, communication with other devices can be used through the serial port to realize the interoperability between devices.

in conclusion

As an important part of modern electronic devices, serial communication is particularly important in the implementation of FPGA chips.In practical applications, reasonable design and use of serial communication modules can provide convenience and support for communication between devices, and improve the competitiveness and market share of products.
