A computer processor uses a so-called Instruction Set Architecture to talk with the world outside of its own circuitry. This ISA consists of a number of instructions, which essentially define 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 ...

A new study comparing the Intel X86, the ARM and MIPS CPUs finds that microarchitecture is more important than instruction set architecture, RISC or CISC. If you are one of the few hardware or ...

A new paper from the University of Wisconsin tackles the question of whether ARM or x86 is more power efficient with updated processors and results from China's Loongson processor. Does ISA still ...

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 ...

Ten years ago, I waded into the then-raging “Mac vs. PC” wars with a lengthy treatise on “RISC vs. CISC: the Post-RISC Era.” In the conclusion to that article, I declared the “RISC vs. CISC” debate ...

Reimagining business for the digital age is the number-one priority for many of today's top executives. We offer practical advice and examples of how to do it right. Read now We tend to think of the ...

A "RISC" ISA has fixed length, small, instructions that do little work and are complemented with lots of registers. A "CISC" ISA has large, variable length instructions that do lots of work, but have ...

Reduced Instruction Set Computer Architecture (RISC) is an instruction set architecture (ISA) which implies a basic bridge between hardware and software. RISC enables the communication between an ...
