Cytocomputation is a computational paradigm based upon the macromolecular activity inside the cytoplasm of the biological cells. This paradigm can be used either as a source of inspiration for proposing novel computational architectures, or as a framework for modeling biological processes at the intracellular and intercellular levels. This paper presents the main characteristics of the paradigm and describes its implementation on the ubichip, a hardware platform specifically designed to support bioinspired architectures.
