The GW3300 integrates GEO’s patented eWARP® core with a Tensilica® Xtensa CPU and DDR3 interface, providing a powerful platform for addressing complex video applications.

The GW3300’s fully programmable geometric processing engine provides the flexibility and performance to correct pincushion/barrel distortion and keystone artifacts for video projection systems such as Head-up Display, Pico Projector, home theater, and business projector applications or large area projector installations such as stadium and tradeshow installations. The processor also provides a solution for multi-projector systems providing 1/32nd pixel accuracy for precise convergence and alignment using AutoCal®, followed by and stitching to create a seamless unified video image.

Real-time programmability using the embedded eWARP® APIs enables designing simple efficient user interfaces for aligning and calibrating complex systems.
