Memory Bank Optimizer

scripts/bank_optimizer_v2.py is created to find optimized memory banks for the kernels with the objective of minimizing the number of DataMover kernel launches needed to execute the computation graph of the selected TopModelArch.

Instructions

1. Run the selected CModel on FPGA for hostlog_0trace.log to be created.
2. Open hostlog_0trace.log and find the lines that after Dumping bank-crossing logs for and append them.
3. Copy the these lines into bank_optimizer_v2.py, method get_objective and line objective =
4. Assign the allowed banks per kernel like banks_transpose=[1,2] to allow banks one and two to be selected for kernel Transpose, or banks_transpose=[1] to force the kernel to use only the bank one.
5. Run the script.
6. Use the output to configure config submodule of the main DeepPoint-V2-FPGA repository and then rebuild the FPGA image.
