The use of asynchronous design approaches to construct digital signal processing (DSP) systems is a
rapidly growing research area driven by a wide range of emerging energy constrained applications such
as wireless sensor network, portable medical devices and brain implants. The asynchronous design
techniques allow the construction of systems which are samples driven, which means they only dissipate
dynamic energy when there processing data and idle otherwise. This inherent advantage of asynchronous
design over conventional synchronous circuits allows them to be energy efficient. However the
implementation flow of asynchronous systems is still difficult due to its lack of compatibility with industrystandard
synchronous design tools and modelling languages. This paper devises a novel asynchronous
design for a finite impulse response (FIR) filter, an essential building block of DSP systems, which is
synthesizable and suitable for implementation using conventional synchronous syst
