This paper proposes two decoder hardware architectures for the tabled asymmetric numeral systems (tANS) compression algorithm, a software implementation of which is used by Apple and Facebook due to its efficiency. To the best of our knowledge, hardware architectures for the highly efficient tANs algorithm are investigated by the authors so far uniquely. The tANS decoder hardware architectures have...
In this paper two new hardware-based entropy coding architectures for asymmetric numeral systems are introduced, as entropy encoding is one of the major phases in a compression algorithm. The proposed architectures are based on tabled asymmetric numeral systems (tANS). The tabled asymmetric numeral systems combines the speed advantage of table based approaches (e.g. Huffman encoding) with the higher...
