Processor Provides Solution for Automatic External Defibrillator

Wed, 11/02/2005 - 6:56am
CMOS Drake, a medical equipment manufacturer in Brazil, required a processor for its automatic external defibrillator (AED) that provided high performance for ECG analysis while still enabling a lower cost and faster time to market. Analog Devices’ Blackfin Processor—a new breed of 16-/32-bit embedded processors that mates performance with power efficiency for applications where a convergence of capabilities are critical—was selected for this application.

“We had three goals in designing our AED solutions: keep costs low, keep them low-power, and achieve high performance,” said Eduardo Azevedo, biomedical engineer, MSc, CMOS Drake. “Using Blackfin as our core processor, we were able to combine DSP functionality with a multiprocessor—rather than combining disparate processors—enabling seamless control of 32 MB SDRAM, 2 MB flash-to-code storage, compact flash-to-data exchange, and an LCD display. In addition, the combination of Blackfin’s breakthrough functionality and unique architecture with ready-to-use development tools like EzKit helped cut our design time, while supplying a more cost-effective and powerful solution.”

“Medical devices are constantly evolving to better aid the health and lifestyle of all people, but, in order for these devices to properly function, complex algorithms must be computed and the minutest details constantly addressed,” said John Croteau, general manager, convergent platforms and services group at Analog Devices Inc. “Using Blackfin ADI technology throughout the signal chain, CMOS Drake not only achieves the best performance, but also reduced board space and bill of materials to deliver a low-power, life-saving unit.”
