First of all, we need to download the program to epcsx without downloading it to parallel Flash because we can remove the parallel f

1 Basic Theory Section1.1 FrequencyCrossover, yes, this concept is also important. Frequency division refers to a single frequency signal is reduced to the original 1/n, called N-division. The realization of the frequency divider circuit or device called "divider", such as the 33MHZ signal 2 to get 16.5MHZ signal, 3 to get 11MHZ signal, 10 to get 3.3MHZ signal.Frequency division is mainly relative Yu Shijing vibration, with less than that high frequency, the Development board generally according

Want to finish the board to export the FPGA pin definition, I think there is no good way to Baidu, fortunately there are peers on the Internet to share. The effect is very good, to add some of the use of their own experience, is to their own memo.The original view is the rain Zhubo the Lord's share, the original link: http://blog.163.com/[email protected]/blog/static/87378868201241644042371/1.

FPGA Important Design Ideas?1. speed and area swap principles. in the area of speed can achieve a very high data throughput rate, in fact , the string / and conversion, is an area of the idea of Speed change2. Ping-pong operation. 3. The idea of string/and conversion. One of the important techniques for high speed data processing. Here, let me give you an example of a multiphase filter extraction:After extraction, two-way data is processed at a

In some FPGAs, floating-point numbers cannot be manipulated directly, and can only be numerically calculated using fixed-point numbers. For FPGAs, the book that participates in mathematics is the 16-bit integer number, but what if there are decimals in mathematical operations? You know, the FPGA is powerless for decimals, a solution is to use the calibration. The number of the calibration is to calculate the floating point number is enlarged very many

Because I use the four-generation development board of the black gold industry and the central chip uses the cycloneiv e of Altera, read the information on the device's official website and take notes for future reference. The cyclone IV device family has the following features:■ Low-cost, low-power FPGA Architecture:■ 6 K to 150 K logical units■ Up to 6.3 MB of Embedded Memory■ Up to 360 18 × 18 multiplier for DSP processing-intensive applications■

In fact, the verification platform instead of board-level verification.We can instantiate a mem block in Testbench and put a. mif file into the mem block. The. mif file is transferred from a image file by matlab or other exe. On the othe hand, Verilog Bench can write processed data back into a. txt file, which can be transferred back into image b y matlab or other exe.By doing this, we no further need image acquisition gear and image display gear before and after the

understood as in addition to single-chip microcomputer, DSP, FPGA and the like to call out the class of IC, the rest is ASIC. The original microcontroller is not an ASIC. For example, many manufacturers provide the design of the ASIC Gate array, but the above lead layer design can be defined according to customer design to achieve custom logic, this kind of ASIC refers to the main generation.FPGA is a programmable array, the use of a lookup table str

-clock pin, which is the ILA logic.In S6, it is recommended that the global clock output only connect to the clock pins, otherwise it is difficult to cause cabling problems easily. The constraint of adding clock_dedicated_route can reduce this error to alarm and continue to run layout and cabling. It is important to note that this constraint does not force the CLK_WE signal to pass through BUFG, but rather tells the tool to ignore such non-optimized clock resource usage issues. You can see throu

Write a summary to develop a set of specifications for you to view and solve problems later. Goals: Serial work, pipeline work (Time Parallel), and parallel pipeline work (space parallel) are realized through the experiment of the streaming lamp ). Serial work is th

Suppose we ignore the baud rate and Use FPGA to send a frame of serial data... as shown in 12.2, a frame of 11-bit serial port data is sent out using a total of 11 rising edges.

target reflection echo detection algorithm and its FPGA implementation One: Algorithm OverviewA time ago, a project was contacted with a sonar target reflection echo detection. The core function of the sonar receiver is to recognize the echo of the excitation signal emitted by the transmitter in the reflected echo which contains a lot of noise. I will share a few articles on this FPGA-based ECHO recognition

Design Concept of FPGA Asynchronous FIFO (2) First, we will discuss the Gray code encoding method: Let's first look at the 4-bit gray code. When MSB is 0, the positive count is displayed. When MSB is 1, that is, the pointer has already passed through, and the highest digit is flipped. At this time, the gray code is counted in reverse order, the entire set of data is symmetric centered on the maximum value (depth), and each number meets the Gray code

Let's talk about it first. Use FPGA to allow buttons to control the display of digital tubes. If you use Quartus II, you just need to find a book. There are image examples on the Internet. A typical example of FPGA application development. Let the digital display, I still 51 Single-Chip Microcomputer idea, come to an input, then output control. Start with a simple Copy a program from the Internet:/*The deco

The zero crossing detection method is the function of the comparator. It can convert a sine wave of a certain frequency into a square wave or a pulse wave. This is necessary in the test frequency and other places, because FPGA only recognizes the edge, but does not recognize the sine wave. The algorithm is divided into two parts: the determination of the zero point and the generation of the pulse wave. Why do we need to determine the zero point. We
