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 ...

A couple of years ago, Erik McClure (a Microsoft software developer, at the time) published a blog entitled RISC Is Fundamentally Unscalable. This blog was really quite interesting and made some very ...

Instruction Set Architecture (ISA) is a set of instructions defined for the processor’s architecture. These are the instructions that the processor understands. It defines the hardware and software ...

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 ...

RISC is a somewhat misleading term, as a RISC processor doesn't *have* to have fewer instructions in its ISA than a CISC system (Though RISC architectures do tend to try to do so). For example, the ...

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 ...

MUNICH, Germany — For embedded applications in office automation, consumer electronics and industrial systems, Renesas has developed a new 32-bit microcontroller family. Now the company provided first ...

When it comes to personal computing, most of the growth today is in the mobile market, not traditional desktop PCs and laptops. You could say that the PC concept is morphing to include next-generation ...
