Abstract

The invention relates to a device and method for installing avionics electronic software applications, a computer program and a system. The method for installing avionics electronic software applications on a platform comprising a multicore processor is implemented by the device. Each avionics electronic software application includes one or several software processing operations to be executed over a predetermined time period including one or several successive time clusters (TC). The method comprises determining an installation plan for the software processing operations according to a firstinstallation rule and / or a second installation rule, the installation plan defining, for each software processing operation, at least one core and at least one time cluster (TC) that are associated with said software processing operation, the first rule consisting of predetermining a list of authorized combinations of criticality levels for applications intended to be executed during a same time cluster, and the second rule consisting of prohibiting installation of critical software application(s) on one or several cores of the plurality of cores.
