MemOpt: Automated Memory Distribution for Multicore Microcontrollers with Hard Real-Time Requirements

Modern multicore microcontrollers for systems with hard real-time requirements increasingly use a complex memory hierarchy to improve available performance and distribute competing accesses to separate memories. With the additional computing power available, the complexity of the implemented software has also increased. These two factors make an optimized distribution of the existing software to the available memory an increasing problem for the integration into such systems. Therefore, this article presents an algorithm that calculates an optimized memory distribution based on the microcontroller used, a recording of the code execution on the target hardware, a system description and automatically generates the corresponding linker script.
