False alarm: despite a patch notes suggesting otherwise, that mysterious blob of microcode released for many Intel microprocessors last week was not a security update, the x86 giant says. In an email ...

CPU microcode represents low-level instructions essential for the proper CPU functioning, acting as a bridge between the CPU’s architecture and the electronic circuits that execute instructions.

For an old CPU, finding all the valid instructions wasn’t very hard. You simply tried them all. Sure, really old CPUs might make it hard to tell what the instruction did, but once CPUs got illegal ...

This research paper was presented at the 23rd annual ACM Interaction Design and Children Conference (opens in new tab) (IDC 2024) the premier forum for inclusive child-centered design and learning.

The root cause was identified as a flawed microcode, which is essential for managing the low-level operations of the CPU. In response to this issue, Intel extended the warranty for all affected ...

From chip-red-pill/uCodeDisasm: The microcode of the Intel Atom CPUs consists from two large chunks of data – Microcode Triads and Sequence Words. These data are ...

Inside every modern CPU since the Intel Pentium fdiv bug, assembly instructions aren’t a one-to-one mapping to what the CPU actually does. Inside the CPU, there is a decoder that turns assembly into ...

What just happened? AMD has confirmed a security vulnerability in some of its processors, which was inadvertently revealed through a beta BIOS update from Asus. The flaw, described as a "microcode ...

Microsoft has released a new batch of Intel microcode updates for Windows 10 2004, 1909, 1903, and older versions to fix hardware bugs in Intel CPUs. When Intel finds bugs in their CPUs, they release ...
