As simple as a processor’s instruction set may seem, especially in a 1978-era one like the Intel 8086, there is quite a bit going on to go from something like a conditional jump instruction to a set ...
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 ...
On January 8th Intel released new Linux Processor microcode data files that can be used to mitigate the Spectre and and Meltdown vulnerabilities in Intel CPUs. Using microcode files, an operating ...
In a nutshell: Google researchers recently disclosed a stealthy security flaw dubbed "EntrySign" that allowed malicious code execution through unsigned microcode patches on AMD processors from Zen 1 ...
High performance controller designs used bit-slice components for their speed and design flexibility. Speeds of 10-20 million instructions per second (MIPS) are common and the designer can use bit ...
NVidia often takes an interesting approach with its technology, and the firm’s upcoming dual-core Tegra K1-64 is no different. It employs the Denver CPU architecture that implements ARM’s ARMv8 64-bit ...
