acts as a driver. If FPGA cannot be used under this interface, arm startup is only half-left. All arm functions cannot be used.(I am talking to software programmers about how FPGA and PXA255 work collaboratively. They are surprised that FPGA can reuse addresses or use transparent dual-block memory, I am surprised to write different results for reading the same a
programmable, it must be like writing software. The idea of software programming is ingrained, and seeing Verilog or VHDL is like seeing a C language or other software programming language. One of the reading, the analysis of the strips. If these novices always refuse to understand why the FPGA is programmable, not to understand the internal structure of the FPGA, it would be impossible to learn the
Requirement Description: Deep learning FPGA realizes knowledge reserveFrom: http://power.21ic.com/digi/technical/201603/46230.htmlWill the FPGA defeat the GPU and GPP and become the future of deep learning?In recent years, deep learning has become the most commonly used technology in computer vision, speech recognition, natural language processing and other key areas, which are of great concern to the indus
DDR2 Circuit DesignHigh-speed large-capacity cache is an essential hardware in high-speed big data applications. At present, the use of a wide range of high-speed large-capacity memory in FPGA system has a classical low-speed single data rate of SDRAM memory, and high-speed dual-rate DDR, DDR2, DDR3 type SDRAM memory, The DDR series of memory all require the FPGA chip has the corresponding hardware circuit

Many of the friends who have done microcontroller know that after the MCU is burned to write the program firmware, then the program firmware is stored inside the MCU. The program can continue to operate even if the MCU is powered off and then re-energized. This is because the firmware of the MCU is written to write the program firmware to the MCU on-chip program memory ROM, and most modern MCU this ROM is flash memory. Flash memory can be power-down to keep data, so can realize the power-down pr
The advanced embedded market is divided into the following three categories: ARM, DSP and FPGA. ARM is the industry leader, currently almost all Android smartphones use ARM authorized CPU architecture, while DSP (digital signal processor) has been widely used in the early years of the telephone, DVD, communication base Station and other fields. The difference between DSP and arm is that arm is a universal CPU,DSP and a dedicated CPU.

FPGA timing problems and fpga timing problems Recently I made a project ------ 4 1080 p (1920x1080) to synthesize a 4 K (3840x2160,297 M) interface board. When 1080 p goes in and p goes out, the video is played normally. However, when P and 4 K are in progress, the video image will have water ripple. At that time, it was assumed that the timing sequence sent by FPGA
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
Last night, inadvertently saw a news channel on the recent stir-fried "the youngest professor in history" interview, but one of his classmates for the dream of "realistic version" explanation quite a bit intriguing. The general meaning is to say, "fight to get into a dream of the university, parents hard to pay the tuition, we have picked the most easy credit, in order to obtain a good job we have lost the pursuit of the dream." Perhaps this is once i
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

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
