D/AVE Graphics Accelerator Demo From TES
The D/AVE 2D is an Altera® SOPC Builder and VHDL register transfer level (RTL) intellectual property (IP) developed for sophisticated vector-based graphic applications. D/AVE fits perfectly into the requirements of embedded systems.
Feature highlights:
- High quality anti-aliasing
- Subpixel accurate rendering
- Resolutions up to 2048 x 2048
- Extended rendering primitives supported in hardware (lines, circles, circle rings, triangles, quadrangles, and wedges)
- 16 blending modes
- Patterns and gradients with alpha channel on all primitives
- Textures up to 2048 x 1024
- Bilinear filtering
- Render to texture
- Texture blending
- No cost hardware clipping
- Flexible input and output formats for frame buffer and textures
- Very small core size
- Easy core integration
- Fully re-entrant driver
The D/AVE 2D core is available in two different versions. A standard version named D/AVE 2D-TS and a light version named D/AVE 2D-TL. The major difference between the cores is that D/AVE 2D-TL does not support 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.
In the Altera SOPC Builder environment, D/AVE uses the Avalon® bus interface, which is tested on the Cyclone® II, Cyclone III, and Stratix® device families. An AMBA AHB/APB bus interface is also available.
