The Broadcom Xilleon video processor (previously branded as ATI Xilleon and later AMD Xilleon) is a SoC combining a MIPS 4Kc CPU with ASIC for accelerated video decoding, for use in set-top boxes and digital TVs, providing MPEG2 decoding and other functions for major worldwide broadcast networks (including PAL, NTSC, SECAM and ATSC).

The Xilleon line consists of four products, models 210D/H, 226, 240S/H, and 260 respectively with slightly different features including HD deinterlacing, 3D comb filter, dynamic contrast, noise reduction, sharpness, color control, and integrated 2D graphics acceleration.

While AMD announced the completion of acquisition of ATI Technologies on the third quarter of 2006, the Xilleon products would be sold under the AMD brand as AMD Xilleon.

It was revealed that the next generation of AVIVO, named as Unified Video Decoder (UVD) was based on Xilleon video processor to provide hardware decoding of H.264, and VC-1 video codec standards.

A new line of Xilleon video processors for flat panel LCD TVs, named as Xilleon panel processors with four models 410, 411, 420 and 421, were announced on CES 2008. Supporting 1080p video resolution and featuring Technology advanced motion estimation, motion compensation and frame rate conversion technology based on enhanced phase-plane correlation technology, which converts 24 or 60 Hz input video signals to 100 or 120 Hz refresh rates used in most of the LCD TVs by creating additional frames to form a smoother motion.[1]

AMD had signed an agreement with DivX, Inc. to allow several of the future Xilleon video processors to implement hardware DivX video decoding with DivX certification on January 2008.[2] However, as a result of company restructuring, AMD has divested the digital TV chipset business starting from the second quarter of 2008.

On August 25, 2008 the Xilleon line was sold to the semiconductor company Broadcom.[3][4]
