Abstract

The Nexperia PNX1501 media processor is a complete audio/video/graphics system on a chip that contains a high-performance 32-bit VLIW processor, capable of high quality software video, audio signal processing. Based on Philips Semiconductor´s multimedia processing chip Nexperia PNX1501, designs a new H.264 encoder with high performance for real time signal processing. Chooses the rapid integral discrete cosine translation and the advanced hexagon searching algorithm, accomplishes the intelligent optimization and comprehensive debugging for codes. The results of experiments indicate that the encoder can encode all kinds of video data rapidly, and can realize the real time processing for all kinds of video signals.
