A wireless endoscopy capsule represents an efficient device interesting on the examination of digestive diseases. Many performance criteria’s (silicon area, dissipated power, image quality, computational time, etc.) need to be deeply studied. In this paper, our interest is the optimization of the indicated criteria. The proposed methodology is based on exploring the advantages of the DCT/DWT transforms by combining them into single architecture. For arithmetic operations, the MCLA technique is used. This architecture integrates also a CABAC entropy coder that supports all binarization schemes. AMBA/I2C architecture is developed for assuring optimized communication. The comparisons of the proposed architecture with the most popular methods explained in related works show efficient results in terms dissipated power, hardware cost, and computation speed.
