U-BOOT 1. directory structure of U-BOOT The U-boot directory contains 18 sub-directories, which respectively store unmanageable source programs. The files to be stored in these directories have their own rules and can be divided into three types. #65517; the first category of directory is directly related to the processor architecture or development board hardware; #65517; the second class directory contains some common functions or drivers; #65517; the third category is u-boot applications,

Development environment: Quartus II 8.1 + Nios II IDE 8.1 Peripheral function: 4*4 keyboard The custom peripheral is an important embodiment of SOPC system flexibility, and it is a very important design method in SOPC system. In a large number of data needs to be processed, the use of customized peripherals by the specific hardware to achieve, can greatly improve the speed of the system, at the same time to facilitate the system's modularity and int

programmed and reconstructed. Its source program is generally a hardware description language (HDL), and a binary file is obtained through synthesis and other steps. On the bladeRF board, FPGA is just an Altera chip. When there is no built-in non-volatile storage, the FPGA image needs to be reloaded every time it is powered on. This is the case with bladeRF. So when you get the board, there is a firmware on it, but there is no FPGA image. The followi

of the qpf file is: Quartus II Project file type The xml name is named: quartus-qml.xmlThen execute:Xdg-mime install quartus-qpf.xmlIn this way, we have registered a New Type. After you open ubuntu-tweak, you will find the qpf type.The next thing to do is to set the default open program for this new mime type (x-quartus:Xdg-mime default/usr/share/applications/quartus. desktop text/x-quartusNote that in linux, the mime type is suitable

Formula for propagation delay of cabling in PCB The first half is information from altera. The propagation latency (tPD) is the time required to transmit a signal from one point to another. Transmission Line propagation delay is a function of the relative dielectric constant of materials. Propagation delay of micro-Strip Layout You can use formula 5 to calculate the propagation delay of the strip layout. Formula 5: Delayed propagation in the line

The high-speed data acquisition system can transmit and process real-time images captured by the camera, and realize the communication between video capture card and computer. The interface of the system connection camera is using Camera link interface, through the camera link interface, the real-time image is transmitted to the FPGA Image acquisition card for real-time processing, and the communication between the acquisition card and the computer is realized through the PCI interface.

Recently, a big customer in the commissioning of the time, has complained to me, our online debugging tools reveal has been error, error, or diamond flash back. After my detailed debugging, I can be very sure to tell you that this is the customer is not in accordance with the standard use caused.Here I put the correct use of reveal process, write to everyone.First step: Insert Reveal Inserter, click the icon, then come out a dialog box, as followsIf you want to see a signal, drag them below the

Altera's-6,-7,-8 speed level reverse order, Xilinx speed grade forward sort.Not very strictly, "the lower the number, the higher the speed level" This is the Altera FPGA sorting method,"The higher the serial number, the higher the speed level" is the Xilinx FPGA sorting method.Since then, I have not been able to understand how the speed grade, the only concept is: the same chip can have multiple speeds, different speed levels represent different perfo

sign that the data is ready;D) Parity-error is the mark that the check digit is wrong;e) Framing-error is a sign that the frame is wrong;f) data-out[7:0] is the parallel data output terminal.The receiving module starts from capturing to the first 0 of the data string, and then passes the 8 data bits that are subsequently entered sequentially through the shift to complete channeling and conversion in the register, and outputs the parallel data to Port Data-out. After the 8 data bits are shifted

is the current preliminary planning system architecture, the general 6-axis robot will come with a handle, you can teach, programming, complete all the operation. Have thought of using the handle, but that is not the most important, I think with the embedded handle is not as easy to program on the Windows environment PC, recently I use Epson robot to do projects, Epson's RC7 is based on computer control, can not use the handle, network or USB connection, Speed basically can meet the requirements

Iv. timing Analysis of the DAC7512 controller with TimequestWhen timing constraints on an object, the first thing to be able to correctly identify it, timequest in the design of the components according to the attributes of the classification, we are under the time constraint, we can use the command to find the corresponding category of an object.Timequest to the design of the components of the classification of the main cells,pins,nets and ports several. Registers, gate circuits and the like ce

continuous address space, static address alignment is safer. During the debugging, the following problem occurs: IOWR (keyboard_base,) is used; The IRQ interrupt signal is clear, and the SignalTap II logic analyzer cannot catch the write signal and keeps the write signal low, later, IOWR (keyboard_base, 0, 0) will be able to capture the write signal. I think it must be the problem of address alignment. Then I open the system-based file system builder and prepare the address alignment method.

The TCL script starts to add init_tk, and waits before it ends and exits, however, for this wait command, I got a different command from Altera's AE, namely tkwait, that is, whatever it means can achieve the goal. To sum up the detailed operation steps (the SR Summary for AE is as follows ): 1), add th

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

different from the successful Board of others (the design of Altera FPGA/CPLD says data0.dclk is going to be pulled up, the purpose is to give a stable State after the configuration is complete, but there is no need in fact), I am quite depressed, depressed why ASP is not good, depressed why does it work ?? Just a few clicks on the Internet, some people are struggling with the same problem. asp can now be used, but cannot be reloaded and cannot be
