Of course, this is only my opinion, because it seems that many people in the same major do not talk about FPGA application systems, I have always insisted that it is just as wasteful as using P4 CPU to make digital TVs.

Design of High-Speed Data Collection System Based on USB2.0 and FPGA technology [Date:] Source: Electronic Technology Application Author: Yuan Jiangnan [Font:Large Medium Small] 　 In recent years, laptop computers have been rapidly popularized and updated, most of which do not have RS232 interfaces configured, and USB interfaces have become the mainstream of PC and peripheral interfaces in the future. This collection system is des

This paper is a DSP and FPGA communication test based on chuanglong TL665xF-EasyEVM Development Board. The brief introduction of the TL665xF-EasyEV Development Board is as follows: consists of the core board + the bottom board. The core board DSP end adopts single-core tms320c6655 or dual-core tms320c6657 processor, FPGA end adopts Xilinx Artix-7 processor to realize heterogeneous multi-core processor archi

FPGA image processing, from now on, let's give the time to "image processing". My brother, who had hesitated and pondered over a question before writing, had been bothering me, "the position of FPGA in the field of image processing." ”As a rule, let's not go into the answer to this question for a moment, but first we'll talk about image processing technology. In my personal opinion, image processing is abou

In 2014, it was almost half the time before the original FPGA tutorial plan of black gold in 2014 was launched. I'm sorry, haha! As the saying goes, it's not too late to make up for it. I hope you will understand that we are grateful, grateful, and grateful for your support! The original tutorial plan for 2014 is as follows: What we are carrying is [What about FPGA-driver I]. After this tutorial is complete

Typical FPGA development process and precautions The FPGA design process is the process of developing FPGA Chips Using EDA development software and programming tools. Typical FPGA development processes generally include function definition/device selection, design input, function simulation, comprehensive optimization,

Recently, some FPGA boards (ep4ce30f23c8n) were maintained, and we found that there were a pair of ground-to-ground short circuits for both 3.3v and 1.2v FPGA boards. After removing some chips powered by 3.3v, they were still short-circuited, there is no way to simply remove the FPGA chip. As a result, the short-circuit phenomenon disappears. It turns out that th

Label: Ar data sp c time algorithm r Application Programming The essence that spld, CPLD, and FPGA can implement any logic is that any logic can be expressed (or approached) by polynomials ). Polynomials are nothing more than multiplication and addition operations. And exactly, match the door, or match the door plus. FPGA extended architecture: the on-chip programmable system. There are two types: one i

What is an FPGA? FPGA is a field programmable logic array, composed of programmable logic resources (LUT and REG), programmable wiring, and programmable I/O. The basic structure of Xilinx FPGA is the same, but with the development of semiconductor technology, FPGA's logic capacity is more and more rich, faster, embedded more and more hard core, such as: ARM proce

I have been fascinated by the internal resetting of FPGA. I have carefully studied the official data manual over the past two days. I have understood many of my doubts and I feel that I have made some progress ..... I. About POR (power-on Reset) When FPGA is powered on, it first enters the reset mode, clears all Ram bits, and sets user I/O to three States through the internal weak pull-up resistor. The co

FPGA and Simulink combined real-time loop series-openingToday, the FPGA development process is bound to involve a process: verification simulation, validation in many cases is done in MATLAB, and most of the simulation of the beginners are using Modelsim simulation software. For example, design a signal filter module, verify that the filter module is in MATLAB design verification, the module design paramete

, the conversation with a predecessor let me once again determined the technical path to the end of the determination and courage. "After all these years you have gone right, you have no detours ... In any case, technology cannot be lost. " It is also a coincidence that I know the elder. (all sorts of titles pass by), now he is not worried about the "free technical professional", he pursues not what success, is the free pursuit of technology. And in turn,I also talked to a friend in HW years, hi

FPGA supports multiple configuration/loading methods. It can be roughly divided into two types: active and passive. Active loading refers to the configuration process controlled by FPGA, and passive loading refers to FPGA only passively receiving configuration data. The most common passive configuration mode is to download bit files using JTAG. In this mode, the

slowly, maybe the technical background would be my advantage. However, my conversation with a senior gave me the determination and courage to go on the technical path again. "You have been right over the years, and you have not taken a detour ...... In any case, technology cannot be lost ". It is also a coincidence with the understanding of this predecessor ,......
