How Source Code Becomes a Custom Hardware Datapath

Based on your source code and the following principles, the Intel® oneAPI DPC++/C++ Compiler builds a custom hardware datapath in the FPGA’s logic:

  • The datapath is functionally equivalent to the C++ program described by the source. Once the datapath is constructed, the compiler orchestrates work items and loop iterations such that the hardware is effectively occupied.
  • The compiler builds the custom hardware datapath while minimizing the area of the FPGA resources (ALMs, DSPs, and so on) used by the design.
