0 IntroductionWith the widespread popularization and application of embedded system, UART (Universal asynchronous Receiver Transmiller) is widely used as a serial data transmission method. The UART allows full-duplex communication on a serial link. Serial Peripherals to Rs 232-c Asynchronous serial interface is typically implemented using a dedicated integrated circuit, the UART. Common serial interface chips such as 8250, 8251, NS16450, etc., can achieve a more comprehensive serial communicatio

Most devices in the system are operated on the hop-on-line of the clock, which requires that the delay deviation of the clock signal be very small, otherwise, the timing logic status may be incorrect. Therefore, the factors that determine the system clock in FPGA design are

Through the analysis of MATLAB to verify the filtering effect, the audio signal of the superimposed noise signal is output to TXT file. Then use the Matlab language to write the filter module and test module, thr

FPGA adopts the concept of logical unit array (LCA), which includes the configurable logic module CLB (Programmable Logic block) and output input module IOB (input output block) and interconnect. FPGA is a programmable device. Compared with traditional logic circuits and gate arrays (such as pal, gal, and CPLD devices), FPGA has different structures.

Broadly speaking, FPGA configuration includes programming the FPGA device using the download cable, programming the external EEPROM and flash, programming the FPGA device using MPU, and programming the device using the external EEPROM and flash. FPGA Devices are configured in three categories: Active configuration,

this transceiver has helped us implement clock data extraction units, synchronous character source and synchronous character detection modules, and analog front-end modules. What we need to do is how to configure this transceiver. In addition, an important task of the physical layer is to use the OOB (out of band) signal to identify the device and initialize the device upon power-on. Therefore, the physical layer module is further divided here to obtain the following physical layer diagram. The

1. CPLD or FPGA FPGA is suitable for completing time series logic, and CPLD is suitable for completing various algorithms and combination logic; The timing delay of CPLD is even and predictable, while the wiring structure of FPGA determines the unpredictability of the delay; FPGA is more integrated than CPLD an

The clock is the most important and special signal of the entire circuit. Most devices in the system are operated on the hop-on-line of the clock, which requires that the delay deviation of the clock signal be very small, otherwise, the timing logic status may be wrong. Therefore, it is very important to clarify the factors that determine the system clock in FPGA design and minimize the latency of the clock to ensure the stability of the design. 1.1
