Features and Benefits
Saves money and power
• Uses less than 8 MB of external
SDRAM
• Uses 32-bit SDRAM interface
• Proprietary motion estimation algorithm
• Embedded in 8-bit video bitstream
General System Facts
Decreases time to market
• Easy to setup and configure
• 162 MHz MIPS-like RISC processor
with DSP extensions for multiplexing,
demultiplexing, audio encoding and
audio decoding
• 365-pin PBGA package; physical
dimensions: 27 mm by 27 mm
• Input voltages:
Interfaces
Superior video quality
• The rate control algorithm monitors
60 different variables, which results in
a more consistent GOP structure;
thus, scene changes are handled well.
Host Interfaces
• 8- or 16-bit Motorola-style interface, or
• 16-bit Intel-style interface, or
• PCI interface: 32 bits, 33 MHz.
• 1.8 V internal
• 3.3 V I/O
Superior flexibility
System Interfaces
• GPIO (general purpose input/output):
12 pins
• IDC (inter-device communications,
similar to Philips I2C)
• SDRAM
• 32-bit memory interface, using 1Mx16-
5 or 2Mx32-5 SDRAM
• Minimum SDRAM requirement: 4 MB
for encoder, 4 MB for decoder
• Dynamically programmable frame
rates, bit rates, resolution and low delay
mode
• Programmable GOP structure
• Transcoding and transrating among
MPEG-1, -2, - 4 and H.263
• Estimated power consumption under
1.0 W in normal operating mode; onchip
power management
• Boundary scan and assembly testing
compliant with IEEE 1149.1 (JTAG)
and EPI EJTAG 2.0 (extended JTAG)
Superior ingenuity
• MPEG-1, -2, -4 full-D1 interlaced
encoder/decoder
• Low latency support
• MPEG-4 short header support (H.263
baseline support)
Applications
The VW2010 is ideally suited for the
following consumer applications:
• Camcorders and network cameras
• Personal video recorder
• Set-top boxes
• PC capture devices for video capture,
content creation, and display
A/V Input Interfaces
Uncompressed Input (Encoder)
• Video: 8-bit ITU-R.BT-656
