Altera officially has a de2 Development Board, which has rich resources and complete peripherals. It uses ten-layer circuit board design, and the price is naturally high. I made a piece based on the principle diagram, called diy_de2 Development Board. The Development Board uses the core board and bottom board mode for ease of use and can be used in subsequent projects. The core Board uses a 6-layer PCB, while the bottom board uses a 2-layer PCB.

, and NXP's arm also has a built-in USB (full speed) interface. 5. AD/DA (data collection and industrial control): ADI is mainly used for analog chips. Therefore, its ARM chips are basically embedded with AD and DA, and the number of digits and speed are the best. 6. Ethernet (Embedded Web and modem): Samsung and ATMEL are equipped with multiple arm Ethernet controllers, and some NXP arm also have. 7. DSP (Signal Processing): ti dsp is the most famous company. Therefore, the arm produced by t

Git must be installed in the installation NIOS2-LINUX and cannot be installed as per the methods provided by Altera WiKi (enter the command: yum install git-all git-gui make gcc ncurses-devel bison byacc flex gawk gettext ccache zlib-devel gtk2-devel lzo-devel pax-utilslibglade2-devel), can only be downloaded after installation: // install the git dependent package yum install zlib-devel yum install openssl-devel yum install perl yum install cpio yum

development of a dedicated integrated chip, such as you look at the camera inside the chip, a small piece, the integration is very low, the cost is very low, but enough. A cottage camera sold only 30 bucks, buy a piece arm how much money? Later ASIC developed some, called semi-custom ASIC, relatively closer to the FPGA, even in some places, ASIC is a big concept, FPGA is part of the ASIC.FPGA is basically the high-end CPLD (Complex Programmable logic device complex programmable logic device), t

partitions and logiclock regions. This article will take a closer look at how to use incremental compilation. The two main tools used for incremental compilation are design partition and logiclock. First, we need to propose a concept. Most of the online incremental compilation brief descriptions are: Using logiclock for incremental compilation. This is a wrong opinion!Logiclock is not part of incremental compilation. We recommend that you use logiclock during incremental compilation! In addit

The human

initiates configuration and the FPGA passively receives data for reconfiguration. The configuration mode is the JTAG-based Passive configuration mentioned above. The result of this operation is to configure FPGA as a flash reader. 2. After the configuration is complete, the host computer starts to send/receive flash data, and the data channel is JTAG. After FPGA receives data through JTAG, it initiates read/write operations on flash as needed, and writes the data to flash to complete the update

We didn't pay much attention to it before. Altera provided many online debugging methods in Quartus, In section V. In-system design debugging of Quartus II version 7.2 handbook Volume 3: verification, five methods are introduced in Chapter 5: 1. Quick Design Debugging Using Signalprobe Signal Probe The method does not affect the original design functions and layout wiring, but connects the signals to be observed and debugged to the reserved or unus

When using third-party software: Modelsim to simulate Quartus ii lpm, you must add the. V file generated by examples and add the. V file to the Altera library during simulation, as shown below: (By the way, only one testbench top-level file in Modelsim can exist .... None of the books ..) LPM-PLL note: Today, when Modelsim is used for a post-simulation, it is found that there is no output of the PLL. When setting different test cl

described earlier, it is an ASIC-class heterogeneous processor! and a 64-bit processor with a 16nm FINFET process! And it is a processor that uses FPGA to achieve hard acceleration!Intel acquires Altera, which means Intel can't sit. A drama is about to be opened. See.4. What are dual-core, dual-core, and Hyper-threadingDual (Multi) Core: refers to the possession of two (or more) physical core (also known as the kernel), a variety of CPU cores have a

the release of 1.2 there was also announced that (at least) two task forces will be erected. one of them will target integration in high-level programming languages, which tells me that phase 1 of creating the standard is complete and we can perform CT to go for OpenCL 2.0. I will discuss these phases in a follow-up and what you as a user, programmer or customer, can reset CT... And how you can act on it. Another big announcement was that Altera is s

We have already introduced and explained the basic content and design steps of the IPv6 protocol stack in detail in the previous article. Now let's test our module functions, check whether it can be used normally. For detailed development environment and test steps, refer to the following.

After comprehensive consideration, the cyclone II-2C8 of Altera Company is selected as the core chip, as well as external extended SDRAM, Flash, various input/output circuits and maxcompute interface chips, etc, it is also implemented in conjunction with the development kit of the niosii software core processor. The control unit structure 1 is shown. CycloneII-2C8 clock frequency as high as 150 MHz or above, because FPGA internal data storage area

Jiang Yongjiang Altera Cup National Graduate Electronic Design Competition has a simple question of "representing-37 as a three-digit complement code. The instructor with a score raised an objection to the answer as soon as he came up, believing that 1122 (3) The result is incorrect, because "except the highest sign bit", 122(3) = 1 × 32 + 2 × 31 + 2 × 30 = 17. This shows that there are problems in our long-term theoretical teaching of digital circuit

understand that the PCB clock skew value = the time when the clock source reaches the FPGA port-the time when the clock source reaches the external device port, and then ~~ Digest it slowly! We recommend that you refer to the explanation of input_delay for synchronous timing constraints in the article of wind330 Boyou: Http://blog.ednchina.com/wind330/194897/message.aspx The concept of Maximum/minimum latency of input is quite clear, and the concept of Maximum/minimum latency of output is
