Zh:Pandora

Pandora是一个第7代（译注：不同的游戏主机商对于主机产品有不同的分代规则，这里的第七代泛指21世纪后所发布的游戏设备产品）掌上型游戏主机。当它出货时（2009.12），会是目前为止性能最为强大的掌上游戏主机。

Pandora开源掌上游戏机

概述

Pandora基于Linux操作系统，并且所有开发工具都是免费提供的，因此任何人都可以在Pandora平台上自由地开发并发布自己的游戏。

硬件核心

Pandora使用TI （德州仪器） OMAP 3530 SoC （System-on-Chip） 芯片。其包含ARM Cortex-A8处理器、TI C64X可编程DSP、PowerVR SGX 530 3D加速器以及其他辅助原件。

存储器

Pandora第一版包含128MB DDR内存和256MB内置闪存。不过，面向消费者所发行的最终零售版包含256MB DDR内存和512MB内置闪存。外部存储设备由2个支持SDHC的SD卡插槽以及USB接口（可连接标准USB闪存/USB硬盘）构成。

控制/输入设备

Pandora具有2个模拟摇杆、1个十字方向键、4个动作按键、2个食指按键、3个功能键 （start/select/home）以及1个标准QWERTY键盘。

显示设备

Pandora使用1块具备800*480分辨率、16万色并且支持触摸控制的屏幕进行显示输出。

TV-out（电视输出）

Pandora具备使用S-video端子和复合信号端子向电视输出视频信息的能力，并且支持“画中画”和TV与LCD分屏显示功能。

音频

Pandora具有一块HD音频DAC，并且支持使用内置麦克风录音。同时在屏幕两侧内置一对立体声扬声器并使用旋钮控制音量。

键盘

Pandora具有一块QWERTY键盘并额外增加了功能键。不过Ctrl键将被映射到动作键或是食指键的其中之一。

  • 强大的2D和3D硬件加速，参见前述。 [11]

• Input:
  • Buttons, keyboard, microphone, and touchscreen. [12]
  • Directional pad will be a D-pad. [13]
  • Two real analog nubs, with rubber grip, but no click function. A video of the analog nub to be used in Pandora's construction. Update: a custom designed plastic nub is now being used and will remain in the previously planned location.
  • QWERTY keyboard cellphone like thumb typeable. [14]
  • Built-In Microphone [15]

  • USB OTG mini-AB port and fully powered (500 mA) standard-A port. You'll be able to use anything that has drivers. [18]
  • RS-232 will be included, but a level converter will be needed for the UART. [19]
  • Twin SDIO-capable SDHC slots.

• Software:
  • Open2X-type Linux firmware. [20]
  • Custom package system for software installation and updates.
  • Potential Emulation: Nearly any game console which predates the Playstation for which an open-source emulator exists. Nearly any 8 or 16 bit computer system for which an open-source emulator exists.
    • Atari 2600, 7800, 5200, and Lynx

    • Atari 400, 800, and ST
    • Amiga
    • PC (DOSBox)
    • Apple II
  • Possible Software:
    • Will run a version of the X11 window manager and has the option of a full desktop environment.
    • There should be the ability to run normal programs you can run on Modern Linux builds as well, provided it does not exceed 256MB of RAM (excluding any virtual memory for performance reasons) and is ported. This includes a full build of Firefox! Firefox 3.0 uses much less memory and resources, and should run fine on the Pandora.
    • Macromedia Flash is possible on the Pandora with web browsers with some work. Maybe not full Flash support though, but http://www.gnu.org/software/gnash/ can be ported to the Pandora and run up to FlashV7 guaranteed, play Youtube videos (mplayer and VLC can play FLV files just fine, play other movie files from Firefox, and VLC can stream FLV easily) and can work with Firefox or as a standalone program.
    • Advanced multimedia support, including streaming: mplayer, VLC, xine and any other program that is open source is possible. For a general idea of file support for VLC see http://www.videolan.org/vlc/features.html, and for xine see http://xinehq.de/index.php/features.

• Power:
  • Lithium-polymer battery, ~4000mAH.
  • Up to 10 hours battery life under reasonable load 8.5 hours under max cpu load. Up to 100 hours playing MP3s. [22]
  • Can charge through AC adapter or USB. [23]
  • Advanced power management capabilities: only need to set a max clockspeed, when the CPU is not doing anything it automatically HALTs and does nothing to save power.[24]
  • Will be able to suspend to RAM or suspend to disk for longer battery life and faster start up.
