High Performance Scaler (HPS) offers two-dimensional, phase correct data processing for improved
signal quality of scaled video data, especially for compression applications
q
Horizontal and vertical FIR filters with up to 65 taps
q
Horizontal upscaling (zoom) supports e.g. CCIR to square pixel conversion
q
Additional Binary Ratio Scaler (BRS) supports CIF and QCIF formats, especially for video phone and
video conferencing.
q
Interfacing
Dual D1 (8-bit, CCIR 656) video I/O interface
q
DMSD2 compatible (16-bit YUV) video input interface
q
Supports various packed (pixel dithering) and planar video output formats
q
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
q
5 digital audio I/O ports
