Method for detecting abnormalities in an electrocardiogram

A method to provide reliability, power management and load balancing support for multicore systems based on Networks-on-Chip (NoCs) and to efficiently implement architectural support for this method by introducing complex packet handling mechanisms is achieved by modifying the basic network interfaces attached to the cores of multicore computation systems. It also proposes policies to leverage the proposed hardware extensions. This aim is achieved with a method to manage the load of peripheral elements within a multicore system comprising several processing units accessing peripheral elements through a NoC, each processing unit and peripheral element attached to a Network Interface in charge of formatting and driving the packets sent to or received from the NoC, wherein, while considering at least two peripheral elements having a similar function, the Network Interface dedicated to a first peripheral element reroutes the incoming packets to a second Network Interface dedicated to a second peripheral element.
