Nvidia Said to Take On Intel in Tablet Computer Chips
Nvidia Said to Take On Intel in Tablet Computer Chips - Bloomberg
"Trying to replicate the performance of Intel chips using software -- an approach Transmeta tried about a decade ago -- hasn’t worked before because it’s hard to deliver enough performance to run computer programs like Microsoft Corp.’s Windows fast enough, according to In-Stat’s McGregor. Intel’s X86 technology has taken over the PC and server industries, displacing companies such as Motorola Inc., whose chips once ran Apple computers.

Did somebody set the Way Back Machine to the 1990s - when "Motorola" and "computer" were still used in the same sentence? Sheesh... obcsiphc: Good luck to emulators everywhere. As always, they're gonna need it... /daytripper |

There must be patents related to instruction decode that make it hard for others to play, as the ISA and the physical operations of the microprocessor are now separated by microcode for [almost?] all processors outside the embedded space. I don't really know of exceptions. Robert. |

I don't really know of exceptions. Robert. In most modern implementations of x86, certain common instructions are considered hard-coded, while others are emulated through microcode. Most floating point instructions are a series of more basic instructions. Yousuf Khan |

Programmers and others like to talk about ISA's because that's all they understand. ISA is irrelevant now. Whatever obstacles there are to "emulating" x86 have nothing to do with the ISA. Robert. |

Yeah, who's that? It's been said in dozens of different ways by architects (formerly of) both AMD and Intel on comp.arch. It's become almost an obsession with Mitch Alsup, formerly the chief architect of AMD. Robert. |

" http://www.bloomberg.com/news/2010-0...rocessors.html Here's a more pessimistic take on the Nvidia x86 story: SemiAccurate :: Details emerge about Nvidia's x86 CPU "Nvidia is more than capable of implementing the Eagle core in an SoC, but if anything will delay a part, a new core is near the top of the list. There will have to be a lot of tweaking done to the core, or at the very least, a lot of work done on the surrounding components to enable an x86 translation engine. All of this carries a lot of risk, and that risk tends to show up as delays in product shipping. That said, lets assume that Tegra 5, code named T50, will be on time. How is an ARM core related to x86? That is easy, Nvidia is going to use Transmeta-esque code morphing firmware to make the CPU run x86 code. Firmware x86 has two associated problems, one technical, one legal. On the technical side, the problem is simple, speed. ARM A9 CPUs are great for phone level applications, and can reach into the current tablet space, but hit a glass ceiling there. If Eagle doubles the performance per MHz and doubles performance per watt, it will basically be on par with the low end of the Atom-class CPUs, and woefully behind the Nano/Bobcat level of performance." http://www.semiaccurate.com/2010/08/...idias-x86-cpu/ |

Yousuf Khan ooooh..."emulated through microcode" seems rather pejorative, considering the obvious alternative design styles might never yield a functional device in your lifetime ;-) /daytripper |
