There are many ways you can implement an Intel i386 CPU on an FPGA, with the use of original microcode probably being one of the most interesting approaches. This is what [nand2mario]’s z386 project ...

Processors are built by multi-billion-dollar corporations using some of the most cutting-edge technologies known to man. But even with all their expertise, investment, and know-how, sometimes these ...

While it would be nice to have a computer that would last forever, the unfortunate truth is that everything becomes old and outdated. This is particularly true with CPUs, especially as technological ...

AMD has officially confirmed a high-severity security vulnerability in its new Zen 5–based CPUs, and it’s a nasty one because it hits cryptography right at the source: the hardware random number ...

The new attack method can leak privileged kernel memory on CPUs released in the past six years that have hardware mitigations for speculative execution and branch injection attacks like Spectre. Six ...

The new class of vulnerabilities in Intel processors arises from speculative technologies that anticipate individual computing steps. Openings enable gradual reading of entire privilege memory ...

Suppose you’re a Raptor Lake guru (Raptor Lake is Intel's codename for the 13th as well as 14th generations of Intel Core processors). In that case, you might’ve noticed that Intel just rolled out ...

A hot potato: Users with 13th- and 14th-generation Intel desktop processors should begin checking for BIOS updates from their motherboard providers. A new microcode update fixes edge cases that can ...

Intel has confirmed that it's about to issue another microcode update for its 13th-gen and 14th-gen Raptor Lake CPUs, meaning you'll need to update your motherboard BIOS again. As with the raft of ...

Use left and right arrow keys to seek audio. AMD has confirmed a flaw within its signature verification for microcode updates within Zen 1 to Zen 5 CPUs. This security flaw has been dubbed "EntrySign" ...

The Secure Encrypted Virtualization (SEV) function of AMD server processors is less secure than the name suggests: Google researchers found that Epyc processors are sloppy when it comes to signature ...
