Abstract

A wavelet Application Programmers' Interface (API) for the TriMedia TM1000 multimedia processor will be described and demonstrated. The challenge undertaken for this API was to provide a single scalable interface to a subband encoder with acceptable performance at bit rates from 9600 bps to 2 Mbps. Further, the API as designed supports the utilization of multiple TriMedia resources. Specifically, the encoder to be demonstrated, is a fully motion compensated wavelet transform which does not utilize the Discrete Cosine Transform for the encoding of the prediction errors. The video encoder has numerous novel features including an integer valued limited precision wavelet transform; a fully motion compensated wavelet API; integral support for multiple processors; and simple mapping to hardware.
