) Synchronization of data between MCU side and FPGA end.SPI data from the MCU output, MCU and FPGA is not the same clock domain, you can use the simplest D trigger to achieve data synchronization. The edge detection of the rising edge requires two D flip-flops, in order to ensure the synchronization of the SPI data, the other signals are also synchronized through two levels of trigger output.Access Spi_data

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

compilation. If you forget to save it, it is equivalent that you have not modified it. Now let's program C code. In order to standardize the program, I need to make some adjustments to the program for further explanation. Create two folders named driver and main respectively. As shown in, Change hello_world.c to main. C and put it in the main folder. After modification, as shown in Next, let's modify main. in C, I will first introduce the purpose of this Code, which is to control 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 FPGA

Preface: Why is it three? I and II are too lazy to move over. For details, see lazy rabbit. The image is scaled. If you cannot see it clearly, click the image to see the big image. As a simulation tool, Modelsim is an indispensable software for CPLD and FPGA. Before performing the simulation, let's talk about the harmonious installation problem.

Example; This is a question given by the teacher. The goal is to familiarize us with the C language operation of FPGA, so as to prevent low-handed eyes. To be honest, testapp_memory is a test provided by XPS.ProgramThe principle is well understood. It is the process of writing data into and then reading data. However, when talking about our own operations, we also need to use the underlying "address Pointer". It sounds a bit messy, and there is
The first step must be the pin planner, which is the view of the four generations of black gold ep4ce15f17c8. The first is to find that their pin has different color areas, which correspond to different banks respectively. Some designs require that the pin be in the same bank (first, this conjecture is followed by verification ), what does different circles and triangles mean? View --> pin legend In the figure, the pin of several brown backgrounds is used. If you place the cursor on the pin, t
logical replication, we haven't met it yet. Copy the concept first: Logical replication is an optimization method to improve timing conditions by adding area. Its most important application is to adjust the fan-out of signals. In other words, that is, the fan output is very large, so in order to increase the drive capability of this signal, many levels of buffer must be inserted, which increases the path Delay of this signal to a certain extent. In this case, you can assign values to generate t

0 is lit and the value of low three bits [3:0] in Num is separated (6 in this case) to display. When Dig_num is 1 o'clock, light the digital tube 1, separate num[7:4] to display (this separates 5). When dig_num = 2 ~ 5 o'clock, the situation is similar. Any time the value in display is converted to the De Shun signal required by the digital tube.
