BCM2702
®
HIGH-PERFORMANCE MOBILE MULTIMEDIA PROCESSOR
FEATURES
SUMMARY OF BENEFITS
• Very Low Power
• MPEG-4 encode from only 10 mW
• CIF MPEG-4 encode @ 30fps: only 38mW including audio
• NTSC/PAL direct video output
• Based on the new VideoCore^®II processing engine, the
BCM2702 is software compatible with the established
VideoCore^® family, allowing rapid development of next-
generation products and backward compatibility for
applications software.
• VGA MPEG-4 encode/decode at 30 fps with audio
• 8-megapixel JPEG encode and decode
• Ability to process raw Bayer camera data
• 3GP and MP4 file streaming and MMS support
• Multiple format audio recording and playback
• DRM ready
• 64-polyphony MIDI player and music synthesizer
• On-board USB 1.1
• 1.25 MB of on-chip SRAM
• High-quality graphics acceleration for 3D games
• SD, MMC, SDIO and MemoryStick interfaces
• ^{100% programmable}
• Highly integrated solution combining video and audio
processing, polyphonic sound synthesis, an LCD controller,
and SRAM on a single chip.
• Video and multimedia processor for advanced handheld
multimedia products.
• Designed and optimized for video record/playback, mobile TV,
and 3D mobile gaming at extremely low power.
• Fully programmable architecture which enables the full range
of multimedia codecs to be implemented in software. This
provides total flexibility to the system designer without the
costly overhead and time-to-market uncertainty of hardware
accelerators.
• Broadcom provides all the necessary middleware and services
for rapid and seamless integration with a host processor, as
well as a complete development kit with a fully featured
toolchain for rapid development of applications.
