I. SummaryThe FPGA implementation of the algorithm is combined with dsp_builder, Matlab, Modelsim and Quartus II software.Second, the experimental platformHardware platform: Diy_de2Software platform: quartus ii9.0 + modelsim-altera 6.4a (quartus II 9.0) + dsp_builder9.0 + matlab2010bIii. preparation of the software platform 1, software matchingBased on Altera's official documentation, you can see version matching information for Quartus II, Modelsim,

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

Add a gpio from the IP Catalog tag and connect to the 8 LEDs on the Zedboard board. Wh

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
