Abstract

An adaptive LZW algorithm for compressing partial bitstreams of Virtex FPGAs was presented. The adaptations of algorithm were based on analysis of the three-level data regularity of the configuration bitstreams. Partial bitstreams were created through Xilinx module-based partial reconfiguration flow. The experiment demonstrated down to 43.69% compression ratio for partial bitstreams of several real-world applications.
