Last but not least, the structure of convolution neural network is built on FPGA. The FPGA I use is Xilinx's xc6slx45, and the following is the final resource usage One of the most important design is to solve the problem of two-dimensional convolution, I used the shift RAM IP core But there's a problem with using it: you need to get rid of some invalid data. Specifically as follows:

The three-state gate refers to the gate circuit output has 3 kinds of states: high level, low power and high impedance state. A three-state gate is required when more than two devices are used to drive the same signal line.At any one time, there can only be one device drive signal, other devices need to be set to high impedance state.Otherwise, if two devices drive the same signal at the same time, a device output high level, a device output low, for push-pull output, two devices equivalent to t

Arduino uploads data to shell Iot platform and interacts with FPGA. arduinofpga This article implements the interaction between Arduino and FPGA. Of course, there is no new protocol, or it is based on serial communication. Now, learning a serial communication can basically drive most modules, moreover, it can seamlessly interact with various single-chip microcomputer data. Because of its powerful Library Fu

FPGA validation is very important in Soc design, in general, to do some replacement of RAM and FIFO and corresponding code conversion. Specifically, the following steps are divided:1 Replacing Ram,fifo and clocksRAM and FIFO controllers require RAM to be placed on the top of the design, allowing RAM to be bist. Use generate as a sample of RAM to provide readability of the code.2 properly do some peripheral interfaces3 Synthesis with synplifyFor RAM us

Experiment two LED experiment content???? On the basis of experiment one, the test signal produced by Simulink is output to the LED lights on the FPGA Development Board, which will be modified on the generated hardware model, the signal sent to the FPGA is output to 8 LEDs, and the signal is assigned the PIN.Create a model???? In the instruction window of MATLAB, enter the following instruction, Hdlsetuptoo

1. Application background 1.1 The cause of metastable occurrenceIn the FPGA system, if the TSU and th of the trigger are not satisfied in the data transmission, or the release phase of the reset signal is dissatisfied with the recovery time of the effective clock edge (recovery times), the metastable state can be produced. At this time, the trigger output Q is in an indeterminate state for a long period after the effective clock edge, during which the

The FPGA download file is loaded into the internal configuration ram, and then initializes the entire FPGA Circuit Line and sets the initial value of the LUT in the chip. A system initializes the entire FPGA, regardless of its size, therefore, no matter what the design of the same chip, the download file size is fixed, as shown in. Unlike MCU, MCU will generate d

Use these design techniques and ISE function analysis tools to control power consumption The new generation of FPGA is getting faster and faster, with higher density and more logic resources. So how can we ensure that the power consumption does not increase along with this? Many design choices can affect the power consumption of the system, from explicit device selection to small frequency-based state machine value selection. In order to better un

The previous step is the hardware description language and the next step is the FPGA.After learning the hardware description language (Verilog or VHDL), how to continue the FPGA.There is no shortcut in the world, every step has to walk. Learning FPGA is also the case, on the basis of a hardware description language, you can learn the FPGA foundation.Learning Module Division and the definition of the interfa

) light the first led and delay for a period of time. 2) light the second led and delay for a period of time. 3) light the third led and delay for a period of time. 4) light the fourth led and delay for a period of time. 5) Repeat the first step. From the above point of view, we understand that "the generation of the effect of the water lamp" mainly follows five steps in order. This may be a natural way of thinking. Humans are really strange animals. Although human brains operate in pa

Xilinx FPGA learning notes 1-chipscope cannot observe the signal BUFG, xilinx-chipscope Today, I started to try to use chipscope and wrote a simple routine of the Water lamp. There was no problem when I started the Integrated Wiring. However, after chipscope was added, an error was always reported. First case: Using chipscope cannot directly observe the global clock signal, that is, the BUFG signal ----- X The error is as follows: ERROR: Location: 113

Tags: FPGAIn some FPGAs, floating point numbers cannot be operated directly, but only fixed points can be used for numerical operations. For FPGA, the book involved in mathematical operations is a 16-bit integer number. What if there is a decimal number in the mathematical operation? You must know that FPGA is powerless to decimal places. One solution is to adopt calibration. The number calibration is to in

Debug fiber Interface interface with FPGA:Due to the needs of the project, the previous period of time debugging the optical fiber interface, recording some design experience.In the design, FPGA is used to control optical fiber module to complete the transmission of optical fiber data, FPGA uses Xilinx company's Spartan6 lx45t, because of its internal 2 GTP transceiver, can be used as a variety of communica

resolution limit, so in people's opinion LED will always glow but low brightness. Not all peripherals, however, can withstand frequencies as high as 1.5MHz. Many devices contain transistors, but the transistor is a cutoff frequency limit problem, when the output pin through the transistor to amplify the output current, the high frequency will cause the output to fail, so in most cases we need to reduce the PWM output frequency. An arbitrary integer divider can be obtained using the ring
