·该处理器功耗小于500Mw ·该处理器提供实时MPEG-4视频编/解码

at a glance:

• The processor consumes less than 500 mW.
• The processor provides real-time MPEG-4 video encoding and decoding.

The TMS320DM310 DSP-based programmable digital media processor integrates a C54x DSP core with an ARM9 32-bit RISC-processor core. It is one of the first devices of the digital-media-processor family to support real-time MPEG-4 video encoding and decoding at CIF (352×28-pixel) resolution and offers an integrated USB host supporting a direct-print capability. It is code-compatible with TMS320DSCx devices, and it supports both CMOS and CCD image sensors of as much as 6 million pixels with a less-than1-sec shot-to-shot delay. Operating-system support includes Nucleus, Linux, Ultron, VxWorks, and WinCE

Addressing and processing modes: The DM310 processor has an integrated SDRAM controller that supports SDRAM timing as fast as 100 MHz and provides continuous data access with low overhead.

Special instructions or integral-peripheral functions: The DM310 includes integrated USB-host and -device support, a real-time preview engine, integrated SRAM and external memory-interface controllers, 32 general-purpose I/Os, two serial ports, two multichannel, buffered serial ports, two UARTs, four timers, a watchdog timer, and seamless support for Compact flash, Smart Media, MMC/SD (multimedia-card/secure-digital) interfaces, and Memory Stick.
