Optimisation in high level behavioural synthesis is usually performed by applying transforms to the datapath and control graphs. An alternative approach, however, is to apply transforms at a higher level in the process, specifically directly to the behavioural source description. This technique is analogous to the way in which the source code of a conventional sequential programming language may be processed by an optimising compiler. Applying this kind of preprocessing to a number of example behavioural VHDL source descriptions, (which are then fed into a 'conventional' synthesis system), produces structural descriptions which are up to 32% smaller and 52% faster.
