Video output for SoC

[Altera_Forum]

Hi, 

 I am wondering if there are some reference designs for implementing a frame buffer for the Linux part in the FPGA fabric of a Cyclone 5 SoC (to get e.g. an DVI output).  If not: Has anybody done this?  - The frame buffer itself should be easy, but how complex is the driver on Linux side? - Is there any 2D graphic acceleration (e.g. for text output) required? - Any other comments?  Regards,  Thomas

Dear Tentner, 

 Till now I have found only one VIP based reference design for Terasic/Arrow SoCKit (not for Altera Cyclone V SoC board, but the FPGA is the same).  See the following link: http://www.rocketboards.org/foswiki/projects/sockitvideoipvipreferencedesign  The above ref design is available on the terasic website after free registration. (~100 MB)  I hope it will be help.  regards  V.Zs.

Hi voroshazi, 

 thanks for the link. However, as I understood, the frame buffer is only accessed by the application software via some dedicated accesses. It is not a "real" frame buffer for Linux where e.g. boot messages would be displayed or x-server could be used (I should mention that my Linux knowledge is quite basic). Correct?  Regards,  Thomas  www.entner-electronics.com - Home of EEBlaster

This provides the integrated frame buffer with Altera's flavor of Linux and DirectFB:
