4 K (3840 x 2160 @60hz) is increasingly becoming a video trend, and how to connect 4K to a splice is a tricky issue.DP enters into the anx1122, through the ANX1122 the DP input signal to the LVDS signal, and then through the FPGA to the LVDS signal to the Video line field signal, and then the field signal through the SerDes sent out. The output card receives the SerDes signal, then turns it into the line field signal, then does the splicing processing

1. Do a stopwatch example today to introduce the FPGA project with Vivado2. Use two keys key0(stopwatch drive, pause),key1The following demonstrates the Vivado operation Process1.create Project(figure)2. It is usually selected (figure)3. do not select source files (figure)4. Select the chip (we use the xc7a35tftg256-1) can also use filters to select the chip (figure)5. Click Finish, our project is created, but a blank, we will eventually produce a bi

Eight tips for solving FPGA timing problemsAdvice one, if the timing difference is not much, within 1NS, can be modified by the synthesis, layout and routing options to fix, if the difference is much, you have to move the code.Second, take a look at the timing report, pick a path with the most tight timing, and take a closer look at what the reason is, first look at the number of logical series? What kind of circuit is wrong, the multiplier or the Ram

Multi-function Selection of pins involved in FPGA: some pins can be allocated as common I/O pins or programming pins. By default, these special pins are used as programming pins. If you want to use these pins as common I/O Ports, you must set them in the FPGA development tool, select an ordinary IO port. Otherwise, the following error occurs: Error: Can't place multiple pins assigned to pin location pin_30

First, the chip is divided into chip-level and system-level Chip level is, just a chip, such as 51 single-chip microcomputer, you can write a program, download and follow the program to run, before and after the program System level is, can run operating system, such as ARM,SOC, have RAM and ROM Cpu: Computers should understand that the central processing Unit, computer computing core and control core, all of the following chips contain CPU, chip-level MPU: microprocessor, including CPU on

The first experiment simply implements a flashing light program (mainly to review the syntax, simulation, and download process)The basic idea is to use the counter to Count 0.5s, and then change the status of the following led output pins every 0.5sThe hardware circuit is as follows: (the corresponding connection in the FPGA, given in the code comment)　　1. In the last created design file, enter the following:(This experiment is mainly to do a demonstr

For AEs whose key length is 128 bitsAlgorithm. 1. the AES algorithm requires 10 rounds of operations. The most basic implementation is 11 cycles. 2. 16 sboxes are used for each round of encryption, and each sbox occupies 1 2048-bit Rom. Key expansion uses four sboxes. If on-the-fly is performed, a total of 20 sboxes are required. If the key expansion is prepared in advance, 16 sboxes and 1408 bits RAM are required to store the subkey. 3. on Altera FPGA
