  • How to change user parameters You can modify parameters in NeuralNetworkConfig.bsv

    • Parameter description
      • PixelBitSz: Input/weight bit size
      • NumPERows, NumPEColumns: to modify the number of PEs.
        • You need to make the number of PEs to be the power of 2 to get microswitch network work
        • For RS traffic, NumPEColumns should be greater or equal than the FilterSz.
      • PEdelay: the delay of each PE
      • NumChannels, NuMFilters, NumIfMaps, FilterSz, IfMapSz, Stride: Defines the dimension of the target convolution layer to simulate.
        • Please note that it is necessary information for reconfiguration controller and the traffic generator.
        • To run another layer, you need to modify the parameter and compile the simulation again.
  • How to run the compilation ./microswitch -ms : compile a simulation with Weight-stationary traffic ./microswitch -rms : compile a simulation with Row-strationary traffic ./microswitch -rmv : generate Verilog RTL in ./MSVerilog/ ./microswitch -clean : clean up build files ./microswitch -r : run a complied simulation

    • To run the compiler and simulation, you need Bluespec System Verilog (www.bluespec.com) compiler
