D/AVE 2D - graphics rendering IP core for FPGAs and ASICs

D/AVE 2D is a 2D GPU Hardware IP Core, optimized for easy integration into FPGAs and ASICs. Focus of D/AVE 2D is to provide cost efficient high quality vector graphics with subpixel processing and an extended anti-aliasing functionality.

D/AVE 2D has been developed for all applications that benefit from high quality vector graphics. Examples are Graphical User Interface (GUI), Navigation, Dashboard and OSD applications in the Consumer, Wearable, Industrial, Automotive and Aviation area.

D/AVE 2D Variants

The D/AVE 2D core is available in two different variants. A ‘standard’ version named D/AVE 2D-TS and footprint optimized ‘lite’ version named D/AVE 2D-TL. The major differences between both cores are that D/AVE 2D-TL is not supporting performance counting and is slower in terms of pixel processing. The D/AVE 2D-TS render pipeline produces one pixel per cycle, D/AVE 2D-TL needs four cycles for a pixel.Since this peak performance cannot be fully reached in most use cases anyway due to bus bandwidth and latency limitations, the performance difference from application point of view is in the range of a factor of 2-3 instead of 4.

D/AVE 2D-TL feature restrictions vs. D/AVE 2D-TS :

Sub-byte texture formats (1,2 and 4bpp) as well as CLUT formats are not available in D/AVE 2D-Lite.
Color-keying is not available in D/AVE 2D-Lite.
Run Length Encoded textures are not available in the current version of D/AVE 2D-Lite.
Alpha channel blending in the blend unit is not available in the current version of D/AVE 2D-Lite.
