This paper presents novel approach to the Huffman’s asynchronous sequential circuit two valued Boolean switching system design. The algorithm is implemented as software using distributed, service oriented application model with means of the web service component design. It considers method implementation challenges, both towards Moore and Mealy structures with particular respect to the estimation of the Huffman’s minimization algorithm computational complexity. The paper provides implementation details, theoretical model estimation and experimental results that acknowledge the theoretical approach in practice. This paper also examine the multistep design process implementation and its problems inherent in web service based environment both for development and educational purposes.
