Description

Texture mapping unit tailored for Milkdrop acceleration.

This core was designed for Milkymist, a highly integrated opensource VJing platform. See the project page at http://www.milkymist.org. A complete description of the core is available in the Milkymist documentation.

Features

- High performance. Area-optimized implementation reaches 30MPixels/s in a fully running Virtex-4 based SoC with VGA output enabled.
- Low resource usage (approx. 20% of XC4VLX25 slices).
- High clock frequency (SoC meets timing at 100MHz in XC4VLX25).
- Objects are triangle meshes.
- Fade-to-black (decay) feature.
- eGPL license

To be implemented :
- Bilinear filtering.
- Alpha blending.

Status
