Nowadays, it is possible to identify a lot of application areas where a circuit
with the ability to perform different functions according to a particular
situation may prove to be a very efficient means of solution. The most
straightforward approach, how to address this challenge, is to design as many
different circuits, as the overall number of functions that are actually needed
in a given situation. As a next step involved within the execution flow,
individual outputs of these circuits are switched in such way that only the
currently required function will be taken into account. However, main drawback of
this approach can be easily recognized within the resulting size of the target
implementation on a circuit level.
Recent advancements within the field of digital design techniques and components
for digital circuits provide a vital evidence that yet another feasible strategy
may be employed - area and time-efficient design of multifunctional circuits
based on utilization of individual structural elements with multifunctional
features. In this case, the entity of multifunctional circuit is devised as
a compact structure involving set of multifunctional components, where their
low-level interconnection scheme remains untouched in all allowable operating
modes and only the active function of these components is expected to change
intentionally.
Simple circuits could be obviously designed by hand but the growing complexity
renders this approach virtually unfeasible. Proper synthesis techniques have to
be obviously considered. With this drawback in mind, main goal of this article is
to propose completely new approach involving so called Boolean divisors
identification and function kernelling techniques. New synthesis method for
polymorphic circuits will be introduced together with the discussion of the
achieved results.
