During synthesis, Vitis HLS performs the following basic tasks:

  • Elaborates the C, C++ source code into an internal database containing the operators in the C code, such as additions, multiplications, array reads, and writes.
  • Maps the operators onto implementations in the hardware.

    Implementations are the specific hardware components used to create the design (such as adders, multipliers, pipelined multipliers, and block RAM).

Commands, pragmas and directives provide control over each of these steps, allowing you to control the hardware implementation at a fine level of granularity.
