Its real origins, however, are not so pure. The Hexagram. The so-called Star of David is essentially a hexagram, nothing more, nothing less. There is no Biblical or Jewish evidence that traces this ancient occult symbol with king David of Israel.
At its root, IntelÂ® SGX is a set of new CPU instructions that can be used by applications to set aside private regions of code and data. But looking at the technology upward from the instructions is analogous to trying to describe an animal by examining its DNA chain.
The Intel QuickPath Interconnect (QPI) is a point-to-point processor interconnect developed by Intel which replaced the front-side bus (FSB) in Xeon, Itanium, and certain desktop platforms starting in 2008.Prior to the name's announcement, Intel referred to it as Common System Interface (CSI).hus, Intel describes a 20-lane QPI link pair (send and receive) with a 3.2 GHz clock as having a data rate of 25.6 GB/s. A clock rate of 2.4 GHz yields a data rate of 19.2 GB/s. More generally, by this definition a two-link 20-lane QPI transfers eight bytes per clock cycle, four in each direction.
