April 2009 21:24:21 MESZ</span><br></blockquote><blockquote type="cite"><span>To: OLPC Devel <<a href="mailto:devel@lists.laptop.org">devel@lists.laptop.org</a>></span><br></blockquote><blockquote type="cite"><span>Subject: XO Gen 1.5</span><br></blockquote><blockquote type="cite"><span></span><br></blockquote><blockquote type="cite"><span></span><br></blockquote><blockquote type="cite"><span>OLPC is excited to announce that a refresh of the XO-1 laptop is in</span><br></blockquote><blockquote type="cite"><span>progress. In our continued effort to maintain a low price point, OLPC</span><br></blockquote><blockquote type="cite"><span>is refreshing the hardware to take advantage of the latest component</span><br></blockquote><blockquote type="cite"><span>technologies. This refresh (Gen 1.5) is separate from the Gen 2.0</span><br></blockquote><blockquote type="cite"><span>project, and will continue using the same industrial design and</span><br></blockquote><blockquote type="cite"><span>batteries as Gen 1. The design goal is to provide an overall update</span><br></blockquote><blockquote type="cite"><span>of the system within the same ID and external appearance.</span><br></blockquote><blockquote type="cite"><span></span><br></blockquote><blockquote type="cite"><span>In order to maximize compatibility with existing software, this</span><br></blockquote><blockquote type="cite"><span>refresh will continue with an x86 processor, using a chipset from</span><br></blockquote><blockquote type="cite"><span>VIA. The memory will be increased to 1 GB of DDR2 SDRAM, and the</span><br></blockquote><blockquote type="cite"><span>built-in storage will be 4 GB of NAND Flash with an option for 8 GB</span><br></blockquote><blockquote type="cite"><span>(installed at manufacture).</span><br></blockquote><blockquote type="cite"><span></span><br></blockquote><blockquote type="cite"><span>The processor will be a VIA C7-M [1], with plans on using one whose</span><br></blockquote><blockquote type="cite"><span>clock ranges from 400 MHz (1.5 W) to 1GHz (5 W). The clock may be</span><br></blockquote><blockquote type="cite"><span>throttled back automatically if necessary to meet thermal constraints.</span><br></blockquote><blockquote type="cite"><span></span><br></blockquote><blockquote type="cite"><span>The enabling chipset is hot off the fab line, the VX855 [2]. This</span><br></blockquote><blockquote type="cite"><span>single chip provides the memory interface, a 3D graphics engine, an HD</span><br></blockquote><blockquote type="cite"><span>video decoder, USB, SDIO, and other system interface and management</span><br></blockquote><blockquote type="cite"><span>functions, in a low power and small footprint package. One change</span><br></blockquote><blockquote type="cite"><span>induced by the chipset change is a move from AC'97 to HD Audio.</span><br></blockquote><blockquote type="cite"><span>This brings higher sampling rates and allows an upgrade to a stereo</span><br></blockquote><blockquote type="cite"><span>external microphone (and DC sensor) input.</span><br></blockquote><blockquote type="cite"><span></span><br></blockquote><blockquote type="cite"><span>The CaFE chip is being retired, and replaced with an external Flash</span><br></blockquote><blockquote type="cite"><span>management controller, possibly one of the low cost SSD controllers</span><br></blockquote><blockquote type="cite"><span>currently being tested. The camera will now be tied directly to the</span><br></blockquote><blockquote type="cite"><span>VX855's video capture port.</span><br></blockquote><blockquote type="cite"><span></span><br></blockquote><blockquote type="cite"><span>The network interface will be upgraded to an 88W8686, which will halve</span><br></blockquote><blockquote type="cite"><span>its power dissipation and move it to an SDIO interface (further</span><br></blockquote><blockquote type="cite"><span>dropping the power consumption). The current goal is to locate it</span><br></blockquote><blockquote type="cite"><span>in a removable module, allowing its replacement for repair. It will</span><br></blockquote><blockquote type="cite"><span>remain powered while the laptop suspends, waking the laptop if a</span><br></blockquote><blockquote type="cite"><span>packet addressed to it arrives. It is likely that early production</span><br></blockquote><blockquote type="cite"><span>models will not directly support 802.11s (i.e. forwarding mesh packets</span><br></blockquote><blockquote type="cite"><span>while the interface is asleep), but we are working with Marvell on</span><br></blockquote><blockquote type="cite"><span>several different 802.11s solutions.</span><br></blockquote><blockquote type="cite"><span></span><br></blockquote><blockquote type="cite"><span>Gen 1.5 will continue with the existing display, although OLPC is</span><br></blockquote><blockquote type="cite"><span>working with PixelQi to try to improve the brightness and efficiency</span><br></blockquote><blockquote type="cite"><span>of the screen. The DCON is retained (even though the VX855 includes</span><br></blockquote><blockquote type="cite"><span>much of its functionality) as it provides the low power interface and</span><br></blockquote><blockquote type="cite"><span>the timing controller functions for the existing display.</span><br></blockquote><blockquote type="cite"><span></span><br></blockquote><blockquote type="cite"><span>Overall, the target is to match the Gen 1 XO-1 in power consumption</span><br></blockquote><blockquote type="cite"><span>while making aggressive suspend easier, and in price (while changing</span><br></blockquote><blockquote type="cite"><span>to components which are more likely to decrease in price). It is</span><br></blockquote><blockquote type="cite"><span>likely that both goals can be met.</span><br></blockquote><blockquote type="cite"><span></span><br></blockquote><blockquote type="cite"><span>We also expect the Gen 1.5 machines to ship with an OLPC 8.2.x</span><br></blockquote><blockquote type="cite"><span>software release, modified to support Gen 1.5's new hardware but</span><br></blockquote><blockquote type="cite"><span>otherwise unchanged from the current production software release and</span><br></blockquote><blockquote type="cite"><span>compatible with our current software in the field. Gen 1.5 machines</span><br></blockquote><blockquote type="cite"><span>will be deployed in environments already populated by Gen 1 machines,</span><br></blockquote><blockquote type="cite"><span>so seamless software interoperability is an important goal.</span><br></blockquote><blockquote type="cite"><span></span><br></blockquote><blockquote type="cite"><span>Early versions of the hardware (bare board) should be available for</span><br></blockquote><blockquote type="cite"><span>driver development at the end of May. A larger number of prototype</span><br></blockquote><blockquote type="cite"><span>laptops (several hundred) for software development and testing will</span><br></blockquote><blockquote type="cite"><span>become available around the end of August. The OLPC contributors</span><br></blockquote><blockquote type="cite"><span>program will be the preferred way of requesting a Gen 1.5 machine for</span><br></blockquote><blockquote type="cite"><span>testing your software for compatibility or development. We hope to</span><br></blockquote><blockquote type="cite"><span>use the contributors program to ensure Gen 1.5 support for the wide</span><br></blockquote><blockquote type="cite"><span>variety of application and OS solutions created for Gen 1.0.</span><br></blockquote><blockquote type="cite"><span></span><br></blockquote><blockquote type="cite"><span>We're excited to be finally able to make this news public. While</span><br></blockquote><blockquote type="cite"><span>members of the technical team have been working on this for several</span><br></blockquote><blockquote type="cite"><span>months, it was not until last week that we could with any certainty</span><br></blockquote><blockquote type="cite"><span>say that we were going to refresh the hardware and what that refresh</span><br></blockquote><blockquote type="cite"><span>was likely to be. We're now committed to this project and look</span><br></blockquote><blockquote type="cite"><span>forward to working with you to make it happen.</span><br></blockquote><blockquote type="cite"><span></span><br></blockquote><blockquote type="cite"><span>---John, Ed, and the OLPC Tech team.</span><br></blockquote><blockquote type="cite"><span></span><br></blockquote><blockquote type="cite"><span>========</span><br></blockquote><blockquote type="cite"><span></span><br></blockquote><blockquote type="cite"><span>[1] <a href="http://www.via.com.tw/en/products/processors/c7-m_ulv/"><a href="http://www.via.com.tw/en/products/processors/c7-m_ulv/">http://www.via.com.tw/en/products/processors/c7-m_ulv/</a></a></span><br></blockquote><blockquote type="cite"><span>[2] <a href="http://www.via.com.tw/en/products/chipsets/v-series/vx855"><a href="http://www.via.com.tw/en/products/chipsets/v-series/vx855">http://www.via.com.tw/en/products/chipsets/v-series/vx855</a></a></span><br></blockquote><span></span><br><span></span><br><span></span><br><span>_______________________________________________</span><br><span>olpc-de mailing list</span><br><span><a href="mailto:olpc-de@lists.laptop.org">olpc-de@lists.laptop.org</a></span><br><span><a href="http://lists.laptop.org/listinfo/olpc-de">http://lists.laptop.org/listinfo/olpc-de</a></span><br><span></span><br></div></blockquote></body></html>
