Electrocardiogram Signals Digital Processing in a Distributed Computing System

The aim of the work was to determine the relationship between the workload of the microcontroller measuring the electrocardiogram signals and the data stream from the microcontroller to the central server via the Internet, depending on the distribution of computational operations between them. The electrocardiogram signals were processed in a sequence of independently controlled digital filters, which gradually led to a decrease in data flow. The paper presents the results of modeling the operation of digital electrocardiogram signal processing algorithms for harvard architecture 8-bit RISC single-chip microcontroller in MatLAB environment with an estimation of time computational complexity. Estimates of the computational complexity of each of the stages of signal processing, the load of the microcontroller that implements these stages, as well as estimates of the change in the data stream at the output of the microcontroller when implementing a complete or reduced sequence of stages are given.
