The target audience of L2 API are users who have a certain understanding of HLS and programming on FPGA and want to make modifications on kernels, including:

  1. Operator combinations in the kernel, like the number of operators or operator pipeline. Most L1 APIs and glue logics inside L2 kernels are connected with streams. Users could add more operators into kernels to increase its performance as long as it is not bounded by other factors like logic resource and memory bandwidth.
  2. Add more pre-processing and post-processing to kernel, like compression / decompression. Certain DBMS might store its data in compressed format to save the memory space and bandwidth to transfer. Adding decompression module to build longer processing pipeline will save the time to decompress the data and increase system performance.
  3. Kernel combination to be built on single cards. People might be interested in adjusting the kernel combination to accelerate the execution plan with different weights.
  4. Building configs to improve frequency or migrate to other Xilinx FPGA device.
  5. Test correctness in sw-emu, hw-emu and on-board.
