GF9331
VXP® Motion Coprocessor

The GF9331 is a high performance motion coprocessor that is used in conjunction with the GF9330. Together, the GF9331 and GF9330 provide 10-bit broadcast quality deinterlacing for standard- and high-definition video signals up to 1080p60.

Although the GF9330 can fully function as a standalone deinterlacer, the GF9331 provides added features in the form of a filter selection control bus that enables multi-directional edge and adaptive 3-field vertical motion detection. Edge detection and interpolation removes the edge artifacts that tend to occur while deinterlacing on shallow horizontal edges while vertical motion detection reduces motion artifacts.
