What Make This system unique ?
- 在cpu 和週邊device都power off時,lcd 可以維持在開啟狀態
- Lcd 的reflash rate 可動態設定,減少電源消耗。
- Wireless mesh : 無線網路都可以作router使用,減少ap 的需要。
- Marvell network chip在 main cpu 停止時,依然可以forward packet,盡力完成mesh network 的工作。
(? 真的?)
Software 的說明太多了...
olpc 的整體環境稱作Sugar:
- OS基於Fedora Core修改
- 桌面環境是基於Python, GTK GUI
