1. An electronic device, which, during operation, executes first and second processes (P 1 , P 2 ), of which first processes (P 1 ) are executable in two forms, approximate-solution (P 1 -A) and detailed calculation (P 1 -C), comprising: a processor for executing processes (P 1 , P 2 ); and an electronic unit, which includes a component, via which the electronic unit can direct a corresponding query to the processor and receive a report from the processor back, to recognize whether said processor is active, and which serves for executing first processes (P 1 ) when said processor is active, in which case said electronic unit determines for a first process awaiting execution a relevant approximate solution (P 1 -A) and sets such in place of a detailed calculation (P 1 -C) determined with said processor.
