There are a great many development boards available for various processors these days and they are essential tools for the embedded system engineer.
After an engineer selects a new microcontroller the first thing he/she will do is find a dev kit. One such kit is for the Texas Instruments Sitara AM3517 ARM Cortex-A8 based microprocessor and is great for user graphical interface design as it has a 3D graphics engine, CAN, USB OTG, 3.3 V I/O, and EMAC.
The Craneboard, from Mistral, is a low cost ($203) open source reference platform to help developers leverage the benefits of the AM3517 processor and a host of peripherals. The processor features a POWERVR SGX graphics accelerator sub-system for 3D graphics acceleration to support exciting graphical user interface options while maintaining fast and fluid transitions display and gaming effects and a display sub-system with several features for multiple concurrent image manipulation. It also has a programmable interface supporting a wide variety of displays.
