A new instruction set by the original creator of MIPS aims to reinvent the ultra-low power, high-efficiency processor -- and to do so with an architecture that's fundamentally open and available to ...

RISC-V is, like x86 and ARM, an instruction set architecture (ISA). Unlike x86 and ARM, it is a free and open standard that anyone can use without getting locked into someone else's processor designs ...

Try to investigate the differences between the x86 and ARM processor families (or x86 and the Apple M1), and you'll see the acronyms CISC and RISC. It's a common way to frame the discussion, but not a ...

Prompted by the chipmaker's announcement of the SSE5 instruction-set extensions, Glaskowsky analyzes the ultimate outcome to this old controversy. Peter N. Glaskowsky is a computer architect in ...

Welcome to Upscaled, our explainer show where we dig into the bits of tech that make your gadgets faster. Today, I want to talk about instruction set architectures. Apple announced it's building its ...

RISC vs. CISC wars raged in the 1980s when chip area and processor design complexity were the primary constraints and desktops and servers exclusively dominated the computing landscape. Today, energy ...
