Multicore ECU in Automotive Domain with FPP Scheduling

The aim of ECU group is to research the Multicore architecture for automotive safety applications to meet hard real-time embedded systems timing and reliability constraints. The automotive industry needs to change its architectural approach in developing vehicle electronics systems. By integrating more number of functions in a limited set of ECUs. These new features involve greater complexity in the design, development, and verification of the software applications. Hence, automotive industry manufacturers require efficient tools and design methodologies to fulfill their needs in various aspects. In this project, we address the problem of sequencing the infinite number of runnables on a limited set of distinct cores as the sequencer tasks in order to uniforming the CPU load over time. The paper presents the low-complexity heuristics to partition and build sequencer tasks that execute the runnable set on each core. The scheduling problem is being addressed globally at the ECU level, where other OS tasks are scheduled on the same cores as the sequencer tasks. Further we are reducing the execution time of numerous runnables using intertask communication between distinct Multicore ECU’s in efficient manner.
