This document describes a boot compression/decompression algorithm for ADSP-BF533 and ADSP-BF561 Blackfin® processors. The code included with this document was verified using the VisualDSP++® 3.5 tools suite for Blackfin processors. The project was run on an EZ-KIT Lite® evaluation system for ADSP-BF533 Blackfin processors (ADDS-BF533-EZLITE, Rev 1.2) and on an EZ-KIT Lite evaluation system for ADSP-BF561 Blackfin processors.
