TLDR
In this paper, the authors show that the already proposed encoding scheme is not optimal and present a new one, proving that it is optimal Moreover, they compare the two encodings theoretically and derive a set of conditions which show that, in practical cases, the proposed encoding always offers better compression in terms of hardware overhead.
Abstract
Selective Huffman coding has recently been proposed for efficient test- data compression with low hardware overhead In this paper, we show that the already proposed encoding scheme is not optimal and we present a new one, proving that it is optimal Moreover, we compare the two encodings theoretically and we derive a set of conditions which show that, in practical cases, the proposed encoding always offers better compression In terms of hardware overhead, the new scheme is at least as low-demanding as the old one The increased compression efficiency, the resulting test-time savings, and the low hardware overhead of the proposed method are also verified experimentally
