A Heterogeneous Multi-core Development Platform

Demos including command line and QT demos such as OpenCV, OpenCL, OpenGL demos, and also DSP and PRU environment build up and development demos

Powerful Multi-media Performance

The development board is integrated with SGX544 3D and GC320 2D GPU which are applicable for senior graphic UI, meanwhile, Cortex-M4 GPU IPU2 is specially used in IVA image and video hardware codec

perfectly supports H.264, MPEG4 multiple encoding forms and video hardware decode playing, supports multiple video together with decoding playing, multiple decoding channels up to 1080P@60FPS, supports MJPEG iamge hardware codec, and also the VPE can well support hardware image, video zooming and color spacing converting.

Multiple Expanding Functions

Set LCD resolution and boot logo in UBOOT, 

flash OS image just by an SD card, WIFI, MIPI camera, CPU frequency auto adjusting and appoint a fixed frequency

Pin Diagrams Overview


The AM57X could be widely used in insutrial communication, HMI,factory automation, building automation, machine vision, medical image, measuring, auto multimedia, etc.
