贴一段AMAZON上面找到的主板介绍:
几个关键点 : CPU 自己定制的 ARM结构 ,带视频压缩模块
带一个MDDR 内存 256M
跑得linux
摄像头能达到 60fps
P6MU是给CPU提供电源管理的芯片,有了linux ,视频压缩,WIFI通信,相对都变得简单了
The main board includes the Parrot P6 central CPU of the AR.Drone. The P6 chip has been specially designed for the AR.Drone. It includes a 468 MIPS ARM926EJ Risc CPU and a video accelerator. The main board runs Linux along with AR.Drone software. The main board includes 256 Mb 200 MHz 32 Bits MDDR RAM and 32Mb of NAND Flash. It includes a Wi-Fi chipset from Atheros and an USB Port for direct flashing and future extensions. The Atmel P6MU chip is a power management chipset for the P6 chipset. The main board includes also the 60 FPS vertical camera. The video resolution is QCIF (176*144pixels) which, combined with the accelerometers, provides the AR.Drone horizontal velocity. The Parrot software performs: - Stabilizing and auto piloting of the AR.Drone. - Video compression (from VGA to QVGA and compressed with a MJPEG video codec for the frontal camera, QCIF and MJPEG for the vertical one) and streaming. - Managing the Wi-Fi communication with the external controllers over its own Ad-hoc network. The AR.Drone main board software is fully upgradable. This kit includes 1 navigation board and 4 screws. |
