3.3.1. How Source Code Becomes a Custom Hardware Datapath

Based on your source code and the following principles, the Intel® HLS Compiler builds a custom hardware datapath in the FPGA 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 area of the FPGA resources (like ALMs and DSPs) used by the design.
