FEO is an application framework for data- and time-driven applications in the ADAS domain. The name is an abbreviation of Fixed Execution Order.

Activities are the units of computation. This could be an algorithm which detects and extracts lane information from a provided camera image. Such activities are the building blocks of a task chain which is executed cyclically.

Data exchange between activities is provided by feo::com. Each activity can be configured to read and write messages to a named topic.

A FEO application consist of one or more agents (processes) with one or more workers (threads) per agent. Each activity is statically mapped to one agent and one worker through feo::configuration.
