How do they compare their capacity? "Of course, most of the time, when I design for the customer, I will use the highest capacity products directly, because our products are not sensitive to cost. However, this is still a comparison of the two products, simply write some of

Each column has a separate fast carry chain resource.Slice is

before installing the software, you need to have a software installation package available for download from the Xilinx official website: http://china.xilinx.com/support/download/index.html/content/xilinx/zh/downloadNav/design-tools.html . the downloaded software is as follows: then start installing the ISE14.7 software: (1) in the installation package directory, double-click Xsetup.exe, at which time the

In general, Xilinx Microblaze will be used in the system to do some control classes and simple interface auxiliary work, such as running IIC, SPI, UART and other low-speed interface driver, the FPGA logic function module initialization configuration and do some auxiliary calculation and so on. The code for a class program is generally small, often between more than 10 KB and a KB, so the requirement for storage is usually not too high, and using the F

Original address: http://www.fpga4fun.com/PCI-Express5.htmlXilinx makes using PCI Express Easy-they provide a free PCI Express core (called "Endpoint Block Plus") and a wizard to Configure it, all, and their free version of Ise-ise WebPack.So let's fire up Xilinx CORE generator and select Endpoint Block Plus.The core is inactive, we need to use File--and New project to create a project and select an FPGA (here we are using a D RAGON-E so we select Vir

Recently, I participated in the maxim DIY design competition hosted by eefoucs. I was lucky enough to be shortlisted and will soon be awarded a Zed Development Board. The Q series FPGA has already been expected to be available, and finally we can have a Development Board. I consulted Avnet's Fae in the early stage to get the Mass Production News of the Q series and obtained a preliminary offer. However, the quotation is not reliable and the price is too expensive, at least exceeding our expectat

Click set quantization parameter in the lower left corner and set the filter arithmetic to fixed-point (fixed point.

1 Introduction DDR2 (double data rate2) SDRAM is a new generation memory technical standard developed by JEDEC (Joint Committee for electronic equipment engineering). It is the biggest difference from the previous generation of DDR memory technical standards: although the basic method of transmitting data at the same time with the clock rising/falling edge, DDR2 has twice the DDR pre-read capability (that is, 4-bit pre-Access Technology ). In addition, DDR2 also adds the ODT (with built-in cor

the I_CLK ibuf signal I_CLK_BUFGP or the IBUF signal after the IP i_ip_ibuf. I won't call the police. Third case: With Chipscope can not directly observe the FPGA IO, similar to the second case, the second case is not used for sampling, here is not used to observe and trigger. The same is true for the error:Error:ngdbuild:924-input pad net ' i_ip ' is driving Non-buffer primitives:It is possible to observe the corresponding IBUF signal in the same vein. But if this IO is the clock signal of the

When multiple clock frequencies are used in a project, the following error may occur: Error: XST: 2035-port has illegal connections. This port is connected to an input buffer and other components. AbbreviationsCodeThis encoding method is not highly respected. In a project, it is best not to have multiple clocks, which may cause system instability. In fact, in many cases, we can use enable signals to replace such clock signals, such as a pulse signal obtained by counting. If you m

scheme. The Master Linux CPU core uses the Remoteproc API to control the lifecycle of the remote kernel (life cycle management LCM), assigning system resources to remote processor and creating virtio devices. Communication between software running on different CPU cores is implemented through the Rpmsg API.Key processes for this scenario:(1) Design Bare-metal.elf program based on Remoteproc and rpmsg.(2) Bare-metal.elf is added to the Petalinux project, and subsequent Remoteproc calls bare-meta

Based on their own ZYNQ board, in the above run Petalinux, has been stabilized, after detailed records.Now features: Qspi boot U-boot and KERNEL,VDMA, TPG, OSD, VTC and other IP modules under Linux drive,Next: Initialize disk space on eMMC, kernel on eMMC, OpenCV porting, display cache output implementation, QT portingFinal goal: Dual-core processor one core running Linux, a nuclear bare run or run Ucos, the second core program by Linux to download and start running, do not know it is difficult

Recent research in Xilinx ZYNQ7000 found that the xapp1079-amp-bare-metal-cortex-a9.pdf was unable to achieve dual-core communication in VIVADO14.1SDK, after several days of research to achieve communication General steps in accordance with official documentation, the following are different: 1: When you build FSBL with the new version of Vivado14.1, you add librsa.a if you do not add a compile report-lrsa error 2: Add app_cpu0 and APP_CPU1, use

only be input, Xilinx's CLK pin is not used for clock input, can be used as normal IO.Need to be very careful!!! Two companies on the pin type of the detailed definition, although many similar, but there are a lot of different Oh!!!(3) Altera's IO feature does not have a pull-down resistor! Xilinx's IO structure also has a pull-down resistor.I developed a project encountered such a problem: the transmitter, the power is required to output low level.
