　　元器件交易網訊 4月2日消息，據(jù)外媒報道，北京君正開發(fā)出一款SD卡大小、可運行完整版安卓系統(tǒng)、適用于可穿戴設備的微電腦。

　　這款微電腦被稱為“牛頓”（Newton），是第一款針對基于MIPS CPU的可穿戴設備的開發(fā)包，就像一款用于可穿戴設備的縮小版樹莓派。牛頓將CPU、閃存、WiFi、NFC以及多種傳感器繼承在一塊兩個硬幣大的電路板上。

　　英特爾推出的“愛迪生”也是一款SD卡大小的微電腦，為了增加更多的傳感器，愛迪生較最初尺寸已有所增加。

　　低功耗是延長可穿戴設備續(xù)航時間的關鍵所在，牛頓待機功率為4毫瓦，播放MP3時的功率為100毫瓦。“這意味著一次充電后智能手表的續(xù)航時間可達到30小時以上。”

　　牛頓的MIPS CPU主頻為1GHz，顯卡支持每秒30幀的720p圖像。其他特性包括256KB的L2緩存、WiFi、藍牙附件、UART（異步串行口）、USB以及GPIO接口（通用輸入輸出接口），主板最多支持3GB內存。（元器件交易網毛毛  譯）

　　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.
