The physiological condition of a person is determined in physiological condition determining system by using a sensor for sampling a plurality of heart beats of the person, and using a control unit to perform the acts of: extracting a series of cardiac R-R intervals from the heart beat samples, providing a two-dimensional representation of subsequent R-R intervals, wherein two subsequent R-R interval forms an entry in the two-dimensional representation resulting in a plurality of entries, determining a centroid, an average radius and an average rotation frequency for the plurality of entries in the two-dimensional representation, determining a plurality of distances between the radius and each of the entries in the two-dimensional representation, and determining the physiological condition of the person using the radius in combination with the plurality of distances.

A software architecture uses a source program and retrievable internal-register configuration models corresponding to data that is specific to different types of ICs, and permits configuration of the internal registers of one of the ICs. In one embodiment, the single source program causes the CPU to select and load one of a plurality of respective models for different types of ICs, to translate the loaded model, and to use the translated model to access the internal register in an IC corresponding to the loaded model. In one specific application, a PC executes the source program and configures the internal registers of an IC that is coupled to the PC through the parallel printer port. By providing an IC definition file for different types of ICs, such a PC can be programmed to reconfigure the internal registers of the corresponding ICs without requiring revisions to the source program.
