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 ...

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 ...

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 ...

I was just wanting to know if anyone can tell me if the new athlon mp and xp's are risc chips or if they went to cisc. I know the older AMD chips were all RISC, but not sure of the newer ones. When ...

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 ...

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 ...

SAN JOSE–Looking to alter the embedded chip landscape, startup MemoryLogix Inc. took the Microprocessor Forum last week to unveil the company and disclose the development of a “586-based ...

ARM, along with its core licensees, and Intel,along with its x86 CPU competitors, have recentlytaken action to put to rest any remainingdoubt that both camps were on a collisioncourse—ARM touting its ...
