These extensions expand the x86 instruction set with access to registers and features that improve performance.

## Summary

The `VZEROUPPER` instruction can be used to zero the upper 128 bits of the YMM registers. The architecture documentation recommends using it to eliminate any performance penalties cau...

People increasingly consume ultra processed foods. They includeenergy drinks, mass-produced packaged breads, margarines, cereal, energy bars, fruit yogurts, fruit drinks, vegan meat and cheese, infant formulas, pizza, chicken nuggets, and so forth. Ultra…

We often need to encode binary data into ASCII strings. The standards (e.g., email) to do so include base16, base32 and base64. There are some research papers on fast base64 encoding and decoding: Base64 encoding and decoding at almost the speed of a memory…

Last year we posted an article about Milan’s V-cache performance where we dived into the bandwidth and latency performance of the then-latest innovation by AMD to increase performance of its CPUs. Now, we have already done an article about Zen 4’s V-Cache…

Most people think that they are more intelligent than average. Lack of vitamin C may damage the arteries. Make sure you have enough! A difficult problem in software is caching. Caching is the idea that you keep some values in fast memory. But how do you choose…
