Design the simplest RS232 communication logic, the FPGA implementation will receive the data will be sent out, a total of two data transmission pins, a receive. Divide this communication module into three parts: 1. Baud Rate Control Module 2, send

The PWM output controls an LED light and adjusts the duty ratio of the output signal to change the brightness of the LED light. Because the block module is parallel, it is very convenient to produce a clock module, which no longer needs to be

Recently began to learn Verilog HDL language, right on the hand there is a DE2 from the seniors borrowed an FPGA development board. Take advantage of the holidays to learn. Because there are some C-language basics, it is very fast to look at Verilog

Operating System: Win7 bitDevelopment Environment: Quartus II 12.0 (64-bit) + Nios II 12.0 software Build Tools for EclipseWhen using Quartus, sometimes due to backup considerations, or download other people's hardware engineering from the Internet, the hardware engineering catalog will change, resulting in Nios project can not find sopcinfo files, so that the next software development can not be done. The

First, Altera Quartus II 11.0 Kit IntroductionSo-called paddle, strong hardware and software skills, and more creative thinking, no software platform, but also in vain. Therefore, everything created by the platform--quartus II software installation, opened by 0 of the world, then began.Since bingo 2009 began to contact Fpga,quartus II version of the software from the 5.1 version of n years ago to today's latest release of 11.0, have been used, of cour

Familiar with the following information. The second step, Altera official website to register an account, download a Quartus software. Be familiar with the material on CD. Follow the video requirements to open a Quar

Implementation of image acquisition and Display Based on niosⅱ [Date:] Source: Electronic Technology Application Author: Luo Jun, Wu ksong, Liao Honghua [Font:Large Medium Small] 　 With the development of large-scale integrated circuit design technology, the improvement of manufacturing technology and the increase of the number of logical doors on a single chip, the design of embedded systems becomes increasingly complex. Integrating the entire System into a Chip, that is, t

That is to say, in the niosii ide project, you can simply define alt_main () to implement the user startup sequence and select the Hal service program. If the application requires an alt_main () entry point program, you can copy the default execution as the start point and customize it as required.========================================================== ======Differences between alt_main and main[21:36:00 | by: caopenly]What is th

The SDRAM chip is used to dynamically execute debugging programs. The SDRAM chip used in the system is Samsung's k4s640432 with a capacity of 8 Mb.Ethernet controller, used to control and operate the NIC chip. The simulator uses this Ethernet port to communicate with the integrated developme

Just saw the news: Altera built Dual Arm Cortex-A9 FPGA released, did not expect the early prediction of Altera built-in hard core FPGA finally become a reality ------ after Xilinx released Qaq, altera finally had a real response; and the most exciting thing was that two arm Cortex-A9 was built in costdown cyclone, it seems that the future of mixed software and h

be normally renewed in the future Quartus II version, if you encounter a problem with the niosii specification change or Quartus II timing, please renew it on your own) Why do we need to establish a niosii system from scratch? 1. You can optimize the system by yourself. 2. Many samples use the hardware-based OpenGL code. You need to build the niosii system from scratch. You cannot use the niosii system established by Altera or Youjing technolo

After you complete the hardware design of the custom peripherals, you need to write software to test the design of the peripherals. Before that, you have to figure out the address alignment in Nios II, for Avalon Slave, there are two kinds of address alignment: Dynamic address alignment and static address alignment. Dynamic address alignment: Dynamic address alignment can automatically accommodate devices with different Avalon master port widths whi

AbstractThe VM is not a new concept. Through the VM, we can write other OS in one OS. If we merge Quartus II into the VM, this will solve some problems that may occur during the use of US us II for a long time. IntroductionUse environment: Windows XP SP3 + virtualbox 4.1.2 + Quartus II 11.0 + DE2-70 In the process of using Quartus II, have you ever encountered the following problems as I did: 1. only one Quartus II license is provided in the company or the real office, or only one license

Install quartus7.2 in linux-Linux general technology-Linux programming and kernel information. For details, refer to the following section. A few days ago, I found the linux version of quartus, which can only be found on the official website of altera. It seems that only versions earlier than 6.0 are available on the Internet, but the machine is still mounted to quartus 7.2. Before leaving in the evening, set thunder to download and shut down.

AbstractIn the previous blog, we learned how to develop a hardware controller and add the software API to enable the Nios II software to effectively control the hardware, and enable the seven-segment provisioner from 0 to 100. Maybe the same student asked, "I want to allow seven display devices to grow from 0 to 100. I used hardware to develop the seven display devices, and the entire list of OpenGL programs could not exceed 50 lines, why is it necess
