Implementation of floating-point operations in FPGA-calibration and fpga floating-point operations In some FPGAs, floating point numbers cannot be operated directly, but only fixed points can be used for numerical operations. For FPGA, the book involved in mathematical operations is a 16-bit integer number. What if there is a decimal number in the mathematical o

In general, there are two FPGA measurement frequency algorithms: frequency measurement and measurement Week. I used the electronic measurement textbook to find the definition. The frequency measurement is to count the input signal period within a certain period of time, while the measurement week is opposite. It is within the input signal period, count the standard signal period. It can be understood that the frequency measurement uses a slow clock to

HDMI (19pin)/DVI (16 pin) features hot swapping detection (HPD), which serves as the basis for the host system to determine whether the HDMI/DVI sends tmds signals. HPD is a detection signal sent from the display to the Computer Host. The hot swapping detection function is to detect this event through the HPD pin of HDMI/DVI when the display and other digital dis

Mainstream notebook can easily support 1080P HD hard decoding, and built-in HDMI high-definition interface, easy to cooperate with LCD TV to see HD blockbusters. But the output of high-definition movies through HDMI, but a friend but encountered only the picture and no sound. According to the truth, HDMI can transmit sound and image at the same time, how to solve

For the configuration process, see "Experiment 2 configuration" Flash_module.v is a 10Hz, 50% duty cycle output function module. To put it simply, the timer switch... The code is relatively simple. Run_module.v is a flow lamp with a scanning frequency of 3.3hz. It is written in the form of a "control module. 16 ~ The 24 rows are 1 ms counters. 28 ~ The 36 rows are

[Serialization] FPGA OpenGL series instances Sequence Signal Generator Based on OpenGL I. Principles In digital circuits, serial signals are a series of periodic binary signals cyclically generated by synchronous pulses. the logic device that can generate such a signal is called a sequence signal generator. according to the structure, it can be divided into two types: Feedback Shift Type and counting type.A shift-type serial signal generator con

Common binary codes and gray codes can be converted to each other. The following is a brief introduction. 8-bit binary code to Gray Code Binary Code Conversion to Gray code: From the rightmost one, one is different from the other on the left, or is used as the value of

High-definition TVs are becoming more common at home, and these high-definition TVs mostly have VGA, DVI, HDMI interfaces. The laptop screen is too small, and most people in the office want an external monitor. So understand the difference between these three kinds of video signal interface, is the premise of choosing suitable display. 1, in advance, the following: Three kinds of connectors have a common needle and the difference between the female n

Therefore, the timing constraints of the I/O ports are also import

volumes of digital processing are very large, in order to increase the speed, commands and data spaces are separated to access two spaces using two buses. At the same time, generally, there is high-speed RAM in the DSP. Data and programs must be loaded to the high-speed slice Ram before they can run. To improve the efficiency of digital computing, DSP sacrifices the convenience of memory management and has many poor support for multiple tasks. Therefore, DSP is not suitable for multi-task contr
