Abstract :
This micro-power voice-controlled video-telephone decoder is suitable for portable button-battery applications. The system is composed of three main logical units selected from a library of reusable low-power macro-cells: a speech recognizer (SR), a programmable system controller (PSC) and a H.263 decoder. The system is expandable through an asynchronous peripheral bus directly connected to the on-chip PSC.
