Classical High-Level Synthesis

Take one thread and a body of code:

• generate a custom datapath containing registers, RAMs and ALUs
• and a custom sequencer that implements an efficient, static schedule

Example:Sequential Long Multiplication

  RA=A
  RB=B
  RC=0
  while(RA>0)
  {
    if odd(RA) RC=RC+RB;
    RA = RA >> 1;
    RB = RB << 1;
  }

Each register has a multiplexor that ranges over all the places it is loaded from.

ALUs and RAMs also need to be instantiated and carefully schedulled.
