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

Abstract: This article introduces the hardware implementation method of Ethernet MII Interface Based on FPGA and extended functions. The hardware structure consists of the control signal module, divider, asynchronous FIFO buffer, and 4b/5b encoding. Key words: M Ethernet MII; FPGA; Parity divider; 4b/5b codec; asynchronous dual-port FIFO Introduction Traditional PC-centered Internet applications have now be

1 Design ContentThis design is based on FPGA audio signal fir Low-pass filter, according to requirements, using MATLAB to read WAV audio files and add noise signal, FFT analysis, FIR filter processing, and analysis of the effect of filtering. 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

When it is crc_error, the high output indicates a CRC checksum error (an error occurred while configuring the SRAM bits). The support of the CRC circuit can be added in the setting. This foot is generally used in conjunction with nconfig feet. That is, if the configuration process fails, reconfigure.4.i/o,clkusrWhen the Enable user-supplled start-up clock (CLKUSR) option is turned

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

Baidu uses FPGA to accelerate SQL queries on a large scaleGuideAlthough our focus on Baidu's work this year is focused on the deep learning initiatives of the Chinese search giant, many others are critical, although not so cutting-edge applications present challenges brought about by big data. As Baidu's Ouyang Jian talked about at this week's Hot Chips conference, Baidu has over 1 EB of data, processes about 100 PB of data every day, and updates 10 b

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
