DirectFB API can be used for the implementation of HAL layer : Go through www.directfb.org Directfb is a complete hardware abstraction layer with software fallbacks for every graphics operation. 2. Can we use DirectFBAPI for the Implementation of HAL Layer and Give example for basic implementation of Direct API. yes, link is http//www.directfb.org/docs/DirectFB_Tutorials/ 3. DirectFB Dirver is depend on the Display driver.. ...as my understanding that ..Display driver is installed , configure and top of this I would able to used DirectFB API. yes Thanks, Madhukumar.
