AbstractIf you connect us II and de2, this tutorial combination matches you. IntroductionThis is the tutorial used by the original tutorial of Altera for us II and de2. It is divided into two versions, namely the sparse and VHDL versions. You can choose your preferred statement on your own, the most common functions of Quartus II and de2 are taken from the beginning to the end in this Tutorial example. Although this example only contains tutorial, it

This article briefly describes how to use the watchdog_timer service and provides a simple example. Environment: Altera Quartus 9.1 SP1 + niosii 9.1 software build tools for eclipse SP1 Step 1. Sample the interval timer core in the System Builder: 1. The interval timer core is named watchdog_timer in the example of the parameter in the system builder. Figure 1 example of interval timer Core 2. Configure the interval timer Core Figur

before the flow, and image processing seems to need FPGA, but in my contact with a few companies (size is not small), they do the image, but even do not have their own FPGA engineers, that they do not use FPGA to do the work of the image algorithm class, At best, the preprocessing of high-speed data stream acquisition or forwarding is only. So, in fact, FPGA can do a lot of things, but the FPGA is not doing much at the moment, in addition, with FPGA, but do not rigidly adhere to the FPGA. This

memory devices167 mhz/333 Mbps for DDR and DDR2 SDRAM devices and167 mhz/667 Mbps for qdrii SRAM devices. The programmable DQSDelay chain allows fine tune the phase shift for the input clocks orStrobes to properly align clock edges as needed to capture data.In Cyclone II devices, all the I/O banks support SDR and DDR SDRAMMemory up to 167 mhz/333 Mbps. All I/O banks support DQS signalsWith the DQ bus modes ofx8/x9, orx16/x18. Table 2–14shows theExternal memory interfaces supported in Cyclone II

PwC, it will also be the first half of the range of mergers and acquisitions, including technology, medicine, entertainment and media, and oil and gas. PwC says semiconductors will be a particularly popular category in technology careers. The financial services company said that "consolidation trends are driving aggressively large-scale trading in the semiconductor, communications and networking equipment sectors," and for example, at the end of May this year, Avago Technologies announced a $37

(data acquisition, industrial control): Analog devices is mainly to do analog chips, so the company's arm chips are basically built-in AD, DA, and the number of bits, speed is the best.6, Ethernet (embedded web, Modem): Samsung, Atmel Company by a variety of arm built-in Ethernet controller, NXP part of ARM also has.7, DSP (Signal Processing): Ti is the most famous DSP, so the company's arm built-in DSP processor; Motolora Company's arm also has built-in DSP.8, Audio/video interface (audio/vide

replacing). Then use the make Uboot command to compile both the Preloader and uboot files. If you only need to compile preloader, use make prelaoder. The process is lengthy and the hardware engineering is recompiled again. The u-boot.img file will be found in the SOFTWARE\PRELOADER\UBOOT-SOCFPGA directory after compilation, and will be found under SOFTWARE\PRELOADER\UBOOT-SOCFPGA\SPL u-boot- Spi.bin. For convenience, create a directory preloader under GHRD and copy the two files to that directo

Turn-friend Crystal sdram_control_4port full page operation bug?Http://www.cnblogs.com/edaplayer/p/3678897.htmlBefore the school to novice FPGA when encountered SDRAM, and now suddenly found online there are a lot of ready-made code, friend Crystal, Altera has a mobile_dram_altera_max_ii_cpld_design_example version of, hehe, Take doctrine really good, later have the opportunity to try to write their own.But when using sdram_control_4port found, full p

Many boards, have seen a chip with CPLD, such as I have seen a R232 level conversion board on the use of the epm240t controller.It was strange to see, what to do, and then think about the level of 232 required is not provided by epm240t. After trying to understand it, it's like talking about such a processor before. Development methods, uses, future trendsCPLD: Development environment Quarctus SoftwareDevelopment language: VHDL and Verilog languageFor example: The CPLD epm240t series of the MAXI

data of the same FPGA can generate different circuit functions. Therefore, FPGA is very flexible to use. It can be said that FPGA chip is one of the best choices for small batch systems to improve system integration and reliability. Currently, Xilinx and Altera are the leading FPGA companies.Arm has strong transaction management functions and can be used to run interfaces and applications. Its advantages are mainly reflected in the control aspect,DSP

In Quartus II, timing analysis is static timing analysis, that is, Stas (static timing analysis ). The object analyzed by STA is a synchronous logical circuit. The path is used to calculate the total latency and analyze the relative relationship between time sequences. The most popular analysis tool in the industry is Primetime, which is based on Altera us. STA is mainly for analysisFmax,Tsu,Th,TcoThese parameters. These parameters are defined as fol

about it. In fact, in fact, it is just hard to describe the speech, you must first use e-phones to think, and then use code to represent the e-phones. B. OpenGL:After learning about the hardware architecture, we started to use the RTL language of the language. C. Mega function:This is also a major feature of this article. In this example, we will use the mega function provided by Altera to compile the design, so that you can naturally learn the me

1. If you do not know the basic theory of Si, do not blindly pursue the use of software. The purpose of simulation is to understand the cause of the problem and avoid the problem.2. If e can, help Doc will be more conducive to software learning (do not read doc as a textbook, but as a tool book to find what we need 3. Typical SI simulation software. It is strongly recommended that new users learn hyperlynx, which is easy to use and will not be confused by complicated simulation parameter setting
