How did the action of the Win95.CIH virus manifest on April 26, 1999 in Kiev
Naturally, the consequences of the virus will for a long time be generalized at different levels. However, the first victim of this virus brought his computer to the EPOS service…

Operating system role

The operating system is the ultimate authority in resolving hardware problems associated with the change of centuries. It is the operating system in most cases that tells applications the current time and date. The latest versions of operating systems correctly handle the change of dates from 12/31/99 to 01/01/2000. And this applies not only to operating systems that receive the date from the BIOS Continue reading

Excellent coprocessor (FPU)

This time it turned out with a floating point. In time, apparently, they lured the team of Dirk Meyer, one of the creators of Alpha 21264. Now the floating point computation unit contains three separate blocks: addition (FADD), multiplication (FMUL) and storage (FSTORE) (see Fig. 1).

The addition and multiplication blocks are fully pipelined. The FPU architecture is such that it can take every clock input: one addition instruction and one multiplication instruction. Continue reading

Z-tracks

In devices with a moving coil there are no pre-fixed positions. Instead, they use a special guidance system (positioning), which accurately brings the heads to the desired track.

The system of precise guidance of the heads on the tracks is called a servo drive, and for its operation a feedback signal is required that carries information about the real relative position of the tracks and heads.

Temperature fluctuations do not affect the accuracy of the drive. When compressing and expanding disks (rotation, temperature), all changes in their sizes are monitored by a servo drive and the positions of the heads are adjusted. Continue reading

But this is not Intel at all!
The ways of AMD and Intel, from our point of view, have long diverged. If earlier it was possible to install at least Intel or at least AMD into the…
