In this paper, we describe an algorithm to improve dictionary based lossless data compression on GPGPUs. The presented algorithm uses bit-wise computations and leverages bit parallelism for the core part of the algorithm which is the longest prefix match calculations. Using bit parallelism, also known as bit-vector approach, is a fundamentally new approach for data compression and promising in performance for hybrid CPU-GPU environments.
