Fall Processor Forum CPU - Reivews One of the most interesting, in my view, the technological developments of 2005 - the last in the last week of October 2005 Fall Processor Forum (FPF earlier - Microprocessor Forum). Forum focuses on, as you can see from the title, the new processors and architectures is traditionally held twice a year, In-Stat/MDR analysis company with the active participation, promotion and sponsorship, the majority of producers semiconductor industry, in one way or another related to the processors.
The session Fall Processor Forum 2005 from producers x86 processors for desktop, mobile and server systems was followed by only one report - Pacifica: x86 Architectural Enhancements to Facilitate Virtualization, read by Kevin MakGratom (Kevin McGrath) from AMD. Judging from the press releases of October, AMD is now more busy advancing issues Alchemy and Geode architectures, as well as a promo for the new shares 15 - month programme AMD Commercial Channel Program. In today's story would not detail the introduction of AMD Pacifica virtualization technology, I think we touch upon the topic later in the integrated material on the Opteron processor architecture.
More manufacturers x86 architectures at FPF 2005 were not, as they say, "but no one, and those Bakhchisarai." Intel has traditionally maintained a company announces its new architectures within the framework of its own technology platform for developers - IDF. Companies VIA, the last year grobovoe kept silent about advances in the development of the kernel VIA Isaiah and the only mass gathering to begin deliveries of processors VIA C7/C7M likely, especially not tell what. If we keep silent about the architecture of Transmeta Efficeon, which lost traces of the spring of 2005 in Hong Kong, after the sale of rights to intellectual Crusoe / Efficeon Hong Kong company Culture.com Technology, a subsidiary of Culturecom Holdings investment company, invest money in all - from comics to Chinese processors.
However, the fact that the x86 architecture actually "have" interests of the Fall Processor Forum 2005, it does not diminish the significance of the forum sessions, as current trends strong growth of domestic demand for modern computer equipment and portable electronics involve multiple parallel development of a wide range of CPU architectures.
Since last year, just three were merged conference, previously considered to be self-sufficient - Microprocessor Forum, Embedded Processor Forum and MEMS Executive Forum. Thus, in a single work week participants Fall Processor Forum 2005 are able to learn all of the new and quite often interrelated technologies in the development of microprocessors, embedded processors and the Micro-Electro-Mechanics (MEMS).
The list of sessions held within the Fall Processor Forum 2005, held under the common slogan The Road To Multicore impressive: were presented to the new generation of server chips, processors for embedded systems, DSP, and more. For reference only to enumerate a list of companies within otmetivshihsya FPF 2005 with the reports. This Broadcom, Fujitsu Limited, P. A. Semi, Hardware Engineering, Azul Systems, ARM, Innovative Silicon, ARC International, Tensilica, videantis GmbH, Microsoft, Green Hills Software, XenSource, AMD, Freescale, STI Design Center, IBM, Texas Instruments, Fulcrum Microsystems, Sonics.
In this brief digest the events of 2005 will limit FPF story only the most interesting report of the conference, for the remaining material, in my view, only interested in narrow specialists.
IBM PowerPC architecture for the Microsoft Xbox 360
In the days of Fall Processor Forum 2005 IBM company - General sponsor activities, the report submitted four of the 19 made. The key steel stories on the development of specialized CPU for the Microsoft Xbox 360, economical 2 - nuclear IBM PowerPC 970MP processor; there was presented a detailed analysis of design Cell processor.
The key event, of course, was the announcement of new IBM processor specifically designed for use in game consoles of Microsoft Xbox 360. Production of the new processor has already started, with just two companies - IBM's own factory in East Fishkill (East Fishkill), New York, and the factory contract chip manufacturer Chartered Semiconductor Manufacturing in Singapore.
The processor was developed in less than 24 months after the conclusion of autumn 2003 contract with Microsoft. Xbox 360 processor, developed by a joint team of specialists from IBM and Microsoft, is a chip SoC (System-on-Chip), executed on the basis of a specialized version of the famous 64 - bit IBM PowerPC kernel, similar to the architecture of Cell (see our article Cell Processor : step into the future) or PowerPC970, but with some important features. Specifically, in the case of Xbox 360 in three identical chip integrated PowerPC kernel with a frequency of 3.2 GHz, combined dispatching XBAR tyres, with the possibility of two independent processing threads each.
Thus, in the case of Xbox 360 can be said of the possibility of up to six simultaneous processing of data flows. IBM developers cared about the possibility of reducing the clock frequency in the case of over-chip, which reduces power consumption in standby mode.
Xbox 360 processor consists of 165 million transistors, the nucleus area of 168 mm ². To reduce energy consumption and increase productivity using 90 nm manufacturing process 10 KE IBM CMOS technology with the use of SOI (Silicon on Insulator).
