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 ...

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 ...

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 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 ...

Today, if you want to build a high-performance computing device, you can almost certainly find all the software you need in a free and open form. The same is not true for the processor chips that run ...

Go read about EPIC, VLIW versus superscalar cores to see what modern computer architects are arguing over, instead of silly ancient terms like CISC vs RISC.<BR><BR>The answer to your question is that ...

A decade ago, an idea was born in a laboratory at the University of California at Berkeley to create a lingua franca for computer chips, a set of instructions that would be used by all chipmakers and ...

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 ...

If you want to buy a new CPU for your desktop PC these days, you're pretty much limited to AMD or Intel processors. But four decades ago, the CPU market was quite different and far more diverse, with ...
