An invention is disclosed for performing entropy encoding in a parallelized manner, using a GPU. In embodiments, an input sequence of integers is received, and run-length encoding is performed on any runs of zeros in parallel operations on the GPU. Then, a plurality of parallelized operations are performed on the run-length encoded sequence to entropy encode the sequence. The value N may be entropy encoded using only N and the value that precedes it in the sequence, N−1, so the encoding may be sub-divided into multiple operations that may be performed in parallel on the GPU. After entropy encoding is performed, a bitstream may be produced using parallelized operations on the GPU.
