Audio processing
l
Time Slot List (TSL) processing for flexible control of audio frames up to 256 bits on 2 asynchronous bidirectional digital audio
interfaces simultaneously (4 DMA channels)
l
Video synchronous audio capture, e.g. for sound cards
l
Various synchronization modes to support I2S and other different audio and DSP data formats
l
Audio input level monitoring enables peak control via software
l
Programmable bit clock generation for master and slave applications.
Scaling
l
Scaling of video pictures down to randomly sized windows (vertical down to 1 : 1024; horizontal down to 1 : 256)
l
High Performance Scaler (HPS) offers two-dimensional, phase correct data processing for improved signal quality of scaled video
data, especially for compression applications
l
Horizontal and vertical FIR filters with up to 65 taps
Horizontal upscaling (zoom) supports e.g. CCIR to square pixel conversion
l
Additional Binary Ratio Scaler (BRS) supports CIF and QCIF formats, especially for video phone and video conferencing.
Interfacing
l
Dual D1 (8-bit, CCIR 656) video I/O interface
l
DMSD2 compatible (16-bit YUV) video input interface
l
Supports various packed (pixel dithering) and planar video output formats
l
Data Expansion Bus Interface (DEBI) for interfacing with e.g. MPEG or JPEG decoders with Intel (ISA like) and Motorola (68000
like) protocol style, capability for immediate and block mode (DMA) transfers with up to 23 Mbytes/s peak data rate
l
5 digital audio I/O ports
l
4 independent user configurable General Purpose I/O Ports (GPI/O) for interrupt and status processing
l
PCI interface (release 2.1)
l
I2C-bus interface (bus master).
General
l
Subsystem (board) vendor ID support for board identification via software driver
l
Internal arbitration control
l
Diagnostic support and event analysis
l
Programmable Vertical Blanking Interval (VBI) data region for e.g. to support INTERCAST, teletext, closed caption and similar
applications
l
3.3 V supply enables reduced power consumption, 5 V tolerant I/Os for 5 V PCI signalling environment.
