Original Kurzfassung:
Encoders play an important role in many areas such
as memory addressing, data demultiplexing, or for interconnect
solutions. However, design solutions for the automatic synthesis of
corresponding circuits suffer from various drawbacks, e.g. they
are often not scalable, do not exploit the full degree of freedom, or
are applicable to realize certain codes only. All these problems are
caused by the fact that existing design solutions have to explicitly
guarantee a one-to-one mapping. In this work, we propose an
alternative design approach which relies on dedicated description
means for both, the specification of an encoder as well as its
circuit. Based on that, synthesis can be conducted without the
need to explicitly take care of guaranteeing one-to-one mappings.
Experiments show that this indeed overcomes the drawbacks of
current design solutions and leads to an improvement in the
resulting number of gates by up to 92%.
