Blackfin at heart of atrial monitor

Lechnologies Research has used Analog Devices’ Blackfin processor in AfibAlert, its recently launched atrial fibrillation monitor. AfibAlert, designed for daily use in the home to record and analyse heart rhythm data, shows the patient whether they should transmit their data to a doctor for further analysis.

AfibAlert uses a Blackfin BF533, which operates the AfibAlert's lcd controller, led outputs, audio generation, flash storage and a/d conversion. The processor also receives data from the microcontroller peripherals and applies digital filtering and mathematical and statistical analysis to provide feedback to the patient.
