Googlers have not only figured out how to break AMD's security – allowing them to load unofficial microcode into its processors to modify the silicon's behavior as they wish – but also demonstrated ...

Video gamers know about cheat codes, but assembly language programmers are often in search of undocumented instructions. One way to find them is to map out all of a CPU’s opcodes and where there are ...

A technical paper titled “Energy-Efficient Exposed Datapath Architecture With a RISC-V Instruction Set Mode” was published by researchers at Tampere University. “Transport triggered architectures ...

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 ...

Cache prefetching is what allows processors to have data and/or instructions ready for use in a fast local cache rather than having to wait for a fetch request to trickle through to system RAM and ...

In context: Microcode is machine instruction sets that load from the BIOS. It acts much like firmware for the PC's processor. According to MSI Marketing Director Eric van Beurden, AMD will be ...

Intel has released microcode updates for several generations of mobile, desktop, and server CPUs to fix a vulnerability that can be exploited to trigger at the very least a denial-of-service condition ...
