The code that drives the decoder is the CPU’s microcode, and it lives in ROM that’s normally inaccessible. But microcode patches have been deployed in the past to fix up CPU hardware bugs ...

[Can Bölük] has a novel solution: By speculatively executing the target instruction and then monitoring the microcode sequencer, he can determine if the CPU is decoding an instruction even if it ...

Bottom line: Chipmakers typically use microcode updates to fix bugs and improve CPU reliability. However, this low-level layer between hardware and machine code can also serve as a stealthy attack ...

Some of the latest developments in ransomware are all around microcode found on CPUs. This is the code just one step up from the hardware that tells the processor how to function and order its ...

These random test generators create microcode test sequences ... Inside each of these classes, a similar structure to the original single-class code was present – a set of implication operators based ...

A new microcode update fixes edge cases that can trigger the Vmin Shift glitch that the company addressed last year. Those whose CPUs are still crashing should take advantage of Intel's extended ...
