元器件交易网讯 4月2日消息，据外媒报道，北京君正开发出一款SD卡大小、可运行完整版安卓系统、适用于可穿戴设备的微电脑。

　　这款微电脑被称为“牛顿”（Newton），是第一款针对基于MIPS CPU的可穿戴设备的开发包，就像一款用于可穿戴设备的缩小版树莓派。牛顿将CPU、闪存、WiFi、NFC以及多种传感器继承在一块两个硬币大的电路板上。

　　英特尔推出的“爱迪生”也是一款SD卡大小的微电脑，为了增加更多的传感器，爱迪生较最初尺寸已有所增加。

　　低功耗是延长可穿戴设备续航时间的关键所在，牛顿待机功率为4毫瓦，播放MP3时的功率为100毫瓦。“这意味着一次充电后智能手表的续航时间可达到30小时以上。”

　　牛顿的MIPS CPU主频为1GHz，显卡支持每秒30帧的720p图像。其他特性包括256KB的L2缓存、WiFi、蓝牙附件、UART（异步串行口）、USB以及GPIO接口（通用输入输出接口），主板最多支持3GB内存。（元器件交易网毛毛  译）

　　A Chinese company has released a computerabout the size of an SD card that can run a full version of Android and shouldmake it easier to build wearable devices.

　　Called the Newton, the computer wasdeveloped by China’s Ingenic Semiconductor and is the first development kit forwearables with a MIPS-based CPU. It’s an integrated board, like a smallerversion of the Raspberry Pi, aimed at those who want to build and prototypewearable devices.

　　Such hardware development kits are becomingpopular, and Intel has also released a miniature computer for wearables, calledEdison. Newton can include a CPU, Flash, Wi-Fi, NFC and various sensors on asingle board about the same length as two U.S. quarters, or two euro coins.

　　The Newton appears to be available now,though it wasn’t clear from the company’s website how much it costs or where itcan be ordered.

　　Ingenic’s chips aren’t new to wearablesmarket—they’re already used in inexpensive smartwatches, said Alexandru Voica,a spokesman for Imagination Technologies, which develops the MIPS architecture.An Ingenic MIPS chip was also used in US$99 Android tablets that hit the marketa few years ago.

　　Intel’s Edison was originally the size ofan SD card but it has been made a bit bigger to incorporate more sensors.

　　Along with wearables, the development kitsfrom Intel are also designed for use in sensor equipment and data-gatheringinstruments. There are trade-offs with the small size, which limits what theboards can be used for. Freescale has a larger board for building prototypes,called Warp, that includes wireless charging and supports a wider array ofsensors.

　　The Newton board isn’t yet compatible withAndroid Wear, but that may happen eventually.

　　“Android Wear is still in development so we can’t claim fullcompatibility yet,” Imagination’s Voica said. “We are, however, the only CPU IPsupplier on the list of Google ecosystem partners, so the MIPS architecture isfully covered.”

　　Intel also plans to make chips compatiblewith Android Wear, but unlike Imagination Intel doesn’t widely license its coreCPU designs, meaning chip makers like Ingenic can’t make x86 processors.

　　Low power consumption is key to the longbattery life wearables need to provide. Newton consumes 4 milliwatts in standbymode and consumes 100 miliwatts during MP3 playback, Imagination said in a blogentry about the board Tuesday.

　　“This means that Ingenic-powered smartwatches can last for 30+ hourson a single charge,” Imagination said.

　　The Newton’s MIPS CPU operates at 1GHz andthe graphics core can play 720p graphics at 30 frames per second. Otherfeatures include 256KB of L2 cache, Wi-Fi and Bluetooth attachments, and UART,USB and GPIO connectors. And the board can support up to 3GB of memory.
