Crossbar Switch
The PLB Crossbar Switch (CBS) creates a flat memory model and implements Unified Memory Architecture
(UMA), which connects multiple PLB master buses to the PLB slave buses, thus allowing two sets of PLB
buses to intercommunicate. Processor, transport, and the audio and video decoders can access memory
through the memory controller.
Digital Audio/Video Subsystem
The MPEG-2 Digital Audio/Video subsystem provides fully-synchronized playback of digital video and audio
programs, with a minimum of interaction from the PPC401B3 processor.
MPEG-2 Video Decoder with OSD
The MPEG-2 video decoder provides decompression, decoding, and synchronized playback of digital video
streams with a minimum of host support. It produces interlaced video output and can support MPEG-2 com-
pressed data streams up to an average rate of 15 Mbps. The video decoder is also backward compatible to
support the ISO/IEC International Standard 11172-2 (11/93) (also called “MPEG-1 Standard”). It supports the
ISO/IEC 13818-2 Main Profile at Main Level.
The decoder also supports MPEG-2 MP@ML compliance with 2MB memory. Only 2MB of memory are
needed to decode full CCIR601 resolution NTSC and PAL encoded MPEG-2 bitstreams. It performs real-time
decoding of all resolutions in 16-pixel multiples, up to and including 720x480x30 or 720x576x25. Horizontal
and vertical lters deliver high-quality video. Chrominance ltering and up-sampling to provide CCIR601 4:2:2
video output. Pan and scan are supported in 1/16 pel accuracy for 16:9 source material. Video rates range
from 1.5 Mbps to 15 Mbps (higher in bursts).
