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 processor, PCIE, Ethernet and so on. In the process technology, Xilinx's 7 Series FPGA uses the

The recent project needs to use differential signal transmission, so we look at the use of differential signals on the FPGA. In Xilinx FPGAs, differential signals are sent and received primarily via primitives: Obufds (differential output buf), Ibufds (differential input buf).Note that when assigning pins, only the pins of the signal_p are assigned, and the Signal_n is automatically connected to the respective differential pair pins, without the LVDS

Generate a positive cosine wave floating point value in MATLAB and quantify it as a 16bit fixed-point waveform value:Another way:The initialization of Xilinx ROM is a cumbersome thing to import into the Coe file.Alteral is a MIF and hex file that has specialized software that can be generated.The format of the Coe file is as follows:memory_initialization_radix=10;Memory_initialization_ve

global clock input ports and 8 digital clock management modules (DCM).I. Xilinx device primitives related to global clock resourcesCommon Xilinx device primitives associated with global clock resources include: IBUFG, Ibufgds, BUFG, BUFGP, BUFGCE, Bufgmux, Bufgdll, and DCM, as shown in 1.1. IBUFG is the input global buffer, which is the head global buffer connected to the dedicated global clock input pin.

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

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
