DUAL POWER SUPPLY MANAGEMENT FOR THE TMS320VC549 DIGITAL SIGNAL PROCESSOR

As use of portable personal electronics such as cellular phones and pagers becomes more widespread, the demands made on these products become more stringent. Consumers want more features and longer battery life. As the heart of these devices, the digital signal processor (DSP) is also under the same pressure to demonstrate increased performance in terms of processing capability and reduced power consumption.

The TMS320VC549 meets this challenge with 100 MIPS performance while exhibiting greatly reduced power consumption over other standard CMOS DSPs. The speed improvement and power reduction have been achieved using an advanced CMOS process capable of full speed performance at low voltage. This combination makes the TMS320VC549 an ideal solution for portable and power-sensitive applications.
