特向大家推荐一款多功能ARM SOC芯片

[复制链接]
 楼主| ysdx 发表于 2008-3-11 22:07 | 显示全部楼层 |阅读模式
ARM, SOC芯片, pd, 数据手册, 音视频
开发系统支持LINUX/WINCE。特别适合做机顶盒、广告*、数码相框、PDA等音视频的东西。功耗很低。我已经用它开发了2款产品，感觉不错。对了，价格很好。谁知道如何把数据手册上传到主页的资料库中？

不能直接说价格。只能说和ST同等功能的比，价格是一半左右

说实在的，很公道很公道。

专用的

要用有市场的CPU,不是最便宜的CPU

CPU是否有市场，大家都不关心。

大家关心的是自己用CPU设计的产品是否有利润。利润何来？产品销量、产品成本、产品销售价格三者恐怕是关键。

。。

楼主，还是说点实际的吧，在哪个地方可以买到这个片子，北京，上海，深圳？<br /><br />有怎样的开发资源可以提供？样片，开发板，linux&nbsp;wince驱动等等。<br /><br />谁分销via的产品？

应该是专用芯片

用专用芯片开发产品对量小的人来说太可怕了，随时会停产
