Following the widespread acceptance and application of logic synthesis, we are on the way to establishing synthesis methodologies which can handle higher levels of abstraction. High-level synthesis is the focal point. It should be able to take a behavioural description of the design, a set of constraints and goals, then construct a structural implementation that performs the circuit function while satisfying the constraints. In order to ensure a smooth transformation and mapping of high-level description onto hardware, a new strategy for high-level synthesis, flexibility damping, is introduced. It allows a large design space to be explored progressively and systematically. It facilitates the propagation of constraints and helps the introduction of user-specified information. To carry out the strategy, two algorithms, resource restricted scheduling and integrated concurrent mapping are developed. Resource restricted scheduling handles complex control structures and schedules operations across basic blocks in order to utilise all the available resources. After the scheduling has established the flexibility of the abstract elements, concurrent mapping is performed to bind operations, storage, and communications onto functional units, register files and buses concurrently. By considering all the resources at the same time, this mapping process ensures an overall minimum cost of implementation.
