Image warping/Texture mapping core: Overview Details Name: warp Created: 26-Jun-2008 20:18:42 Updated: 02-Aug-2008 16:39:24 CVS: browse Other project properties Category :: Video controller Language :: Verilog License :: GPL Phaze :: Design done Standard :: Wishbone compliant core Development status :: Beta Project maintainers Sebastien Bourdeauducq Statistics view Description This core maps a texture to an object defined by a grid of control points. It can be used to apply textures to 3D objects or to warp images. The core also supports fading the colors to black by a controllable amount. The texture, the control points coordinates and the destination image are accessed over a WISHBONE master. A WISHBONE slave also implements a bank of control registers. This core was designed for Milkymist, a highly integrated opensource VJing platform. See the project page at http://lekernel.net/milkymist/ A complete description of the core is available in the Milkymist documentation. Features Up to 128x128 control points (mesh) Highly configurable via registers (mesh size, mesh address, image resolution, ...) Designed in plain Verilog, compatible with the free Icarus simulator Entirely synthesizeable Good performance (about 20MPixels/s written to the destination image on XC4VLX25 with single-cycle WISHBONE master accesses) Reasonable resource usage Status Works in simulation (graphics demo with PLI included) Works on FPGA but not thoroughly tested Synthesis: 18% of the XC4VLX25 slices
