Intel puts out eight new SoCsEP80579 with or without Quickassist

By Charlie Demerjian: Thursday, 24 July 2008, 6:15 PM

INTEL IS REALLY hot on the MID/mobile internet/CE/Embedded market even if the rest of the world really isn't.

To enable this market, the firm has come out with the EP80579 and the EP 80579 with QuickAssist, eight new chip variants in all.

The goal with these System on a Chip (SoC) devices is to save board space and system complexity through integration. To get there, they took a Dothan core, more or less, and pulled the north and south bridge into the same piece of silicon. That gave them the EP80579. Add in a security unit capable of all the latest buzzwords, and you have the EP80579 with QuickAssist (EP80579QA).

The gory details, with QuickAssist

Intel is claiming a 45 per cent smaller footprint with 34 per cent less power used. In addition to the usual items, they are claiming TDM and analogue voice capability, meaning the south bridge they pulled in is one that had a sound card. The end result goes from 600MHz to 1.2GHz, and consumes from 11 to 21W.

Since this is on the Intel embedded roadmap, it has a seven-year guaranteed life cycle, so build your widgets with confidence that you will have chip supplies for 6.75 years longer than you have sales. Fashion dictates that hyperactive teens won't care about last month's gadget because it has rounded, not squared, corners, and the shade of fuchsia is off. The 80579 family also comes in industrial temp ratings, so it may not just be for the hyperactive teen set.

There are eight variants in total at three clocks, 600MHz, 1066MHz and 1.2GHz. The EP80579 consumes 11.5W, 18W and 19W at the respective frequencies, and there is an industrial temp version (-40c to 85c) of the 600MHz variant as well. The -QA model uses 13W, 20W and 21W at the same speeds, and the industrial temp variant is at 1066MHz this time.

All have 256K of L2 cache, and use DDR2 memory from 400-800MHz, but the 600MHz chips can't use DDR2-800. All chips have three GbE MACs with eight PCIe lanes, two USB2 ports, three HSS ports (for telecom uses) and two SATA-2 ports. They also have the usual southbridge interfaces, UARTs, CAN 2.0, SMBus and even SPI should you want to boot the chip someday.

Related to the 80579 announcements, Intel gave a little teaser about the current lineups of SoCs not related to the industrial roadmaps. The consumer electronics line contains Canmore and it's successor Sodaville. For Mids, we have Lincroft, and eventually Moorestown on the horizon.

Intel seems to be taking this 'x86 everywhere' concept literally, no hyperactive teen should be without three on them at all times. The 80579 line brings that one step closer to reality. µ

规格看起来非常美好，不知道这种片上系统会以什么形式提供，怎么能买到呢

Intel宣布首款x86 SoC片上系统

今天，Intel首次大面积公开介绍了其SoC片上系统开发计划，类似于AMD的Fusion计划和NVIDIA的Tegra，Intel的SoC产品也将在一颗芯片内集成处理器、芯片组、I/O总线控制器等不同功能电路，只用一颗芯片即可完成计算机的绝大部分功能，大大方便嵌入式系统和便携设备的开发应用。在这一市场，Intel的首款产品是名为EP80579的整合芯片系列，主要针对企业安全、存储、通讯、行业机器人等嵌入式应用。

简单的说，EP80579在一颗芯片上集成了Pentium M处理器核心，内存控制器MCH和I/O控制器ICH等等组件，各组件间使用FSB前端总线进行通讯。其中的部分型号还引入了QuickAssist技术，内部包含一个“加速服务单元”（ASU），对安全、企业VOIP和数据通路等应用实现加速。

目前，EP80579共有8款产品，分别对应不同的频率、功耗和行业用户关注的工作温度范围，其中4款内建QuickAssist技术。Intel称，使用该平台最高可令嵌入式系统面积缩小45%，功耗降低34%。

Intel表示，目前已经有超过50家客户对EP80579感兴趣，其中一些已经拿到这颗处理器进行开发长达一年之久。预计首批产品本季度内即可登场，而在今明两年间即可大量投向市场。针对嵌入式市场的特殊性，Intel对SoC产品提供长达7年的制造服务。

更为令人激动的是，这仅仅是Intel x86 SoC计划的一个开始。目前在Intel内部已经超过15个SoC片上系统项目正在开发当中。预计首款针对消费电子（CE）产品的SoC芯片代号“Canmore”，预计将于今年晚些时候发布，第二代“Sodaville”则会在明年登场。而在MID市场，大家已经熟悉的“Moorestown”平台，实际上就是以一款Atom核心SoC“Lincroft”为基础构建的，预计在2009/2010年间发布，并首次杀入手机市场。Intel的长远计划是，凭借这些SoC片上系统处理器，5年内我们口袋里的掌上设备将拥有超过10亿个晶体管，带来无与伦比的使用体验。

做消费电子便携产品我不太了解，但是给工业嵌入用地话,要做到可按需裁剪结合应用才有竞争力。不然性能再强也还是单片机的命。

终于看到SPI，timer和看门狗了。
不过能否搞定256个舵机？

256个？都是伺服轴啊？
用RTOS 和中断方式估计有差不多吧。

五轴的大型数控机床要求直线轴1微米旋转轴一毫弧的的分辨率(系统分辨率不是定位精度)，也只要一块VIA C3 这种档次的就够全软件实现了。（不靠DSP）

如果intel能让一个机器蜈蚣有视觉，同时机器蜈蚣只要10美圆成本，intel就有技术实力
