fpga basics

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

This article is originally from V3 College Www.v3edu.org,FPGA training SpecialistIn order to improve the reuse rate of our code, we can write the code of different functions and then connect to the top layer. We give a simple example, the following procedure, we implement the LED water.In the LED module, we first divide the system clock into 1HZ clock, and then use the crossover clock to control the flow of LED lights, but my crossover and led light f

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

FPGA pin Verification Step (quartusii) 1, new TXT file, write pin configuration (no write voltage type) Syntax only set_location_assignment pin-to pin name such as: Set_location_assignment pin_b11-to CLK2 Set_location_assignment pin_g7-to P1db[0] (This is a multi-bit input and output, you need to disassemble the configuration) diagram: 2, new project, choose the type of FPGA you want to use, if not, you

: For details, see the original project under "./experiment02. For the modeling process, see the modeling video "video_exp02 ". 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

[Serialization] FPGA OpenGL series instances Conversion of binary and Gray Codes Using Tilde Gray Code features: There is only one difference between two adjacent code groups. 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

The process of prototyping and validating ASIC using FPGA reference:http://xilinx.eetrend.com/d6-xilinx/article/2018-10/13736.htmlGiven the complexity of chip design, the steps and processes involved in successfully designing a chip are becoming more complex, and the amount of money required is multiplied, and the cycle and cost of a typical chip development project is as follows Can be seen before the chip manufacturing, a lot of energy will be

Reproduced from the network, the author is unknown.I have many years of work on the FPGA study of QQ group administrators, a lot of new recruits for a long time are always repeating asked some very simple but let the novice puzzled questions. As administrators often to the novice to popularize the basic knowledge, but very unfortunate is a lot of rookie with a impetuous mentality to learn FPGA, always anxio

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
