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 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 ...

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 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 ...

CISC processors are inherently more flexible while RISC designs can be more cost effective for specific applications. The real difference in the two can be found in the dedication of your system ...

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 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 ...

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 ...
