Table 27-1 shows two different ways that data compression algorithms can be categorized. In (a), the methods have been classified as either lossless or lossy. ... This is absolutely necessary for many ...

If I use the compression algorithm on a random state array, ... Note, however, that in my example, the topics are just more data and they change too so that would be harder in that particular case.

Most compression algorithms depend upon the energy of the input signal being concentrated at low frequencies, which allows sample-to-sample correlations to be exploited. In contrast, if the input ...

Woodcliff Lake, New Jersey — July 10, 2025 — Semiconductor intellectual property core provider CAST invites electronic system ...

But there is always a tradeoff. There is no “best” compression algorithm for all applications. For example, BZIP2 achieves good compression efficiencies but because it is more complex, it requires ...

For example, novel algorithms have been developed that leverage the induced sorting principle, achieving reduced time and workspace complexities even when handling sparse data sets [1].

Google has introduced a new data compression algorithm, which the company believes will make the Internet faster for all users. Known as Zopfli, the open-source algorithm is said to increase data ...

The newest tool in the data-squishing toolbox is Google's Brotli algorithm. Officially unveiled and released to the world at large today, it's the successor to a different compression algorithm ...
