Abstract: A closed loop feedback system adaptively controls the compression ratio in a Raster Image Processor. The image content is analyzed in real time, and rasterized bitmap is compressed to a sufficient degree to fit into the available frame buffer. This compression may be done by a variety of algorithms depending on image content. The compression ratio is adjusted on the fly by changing the method of compression, more aggressive or selective quantizing of the image, or by a decimation of parts of the image. The algorithms show will execute very efficiently on a Texas Instruments TMS320C82 multiprocessing DSP. Several methods of implementation on the TMS320C82 are shown.
