Resource Optimization of MPSoC for Industrial Use-cases

Abstract: Today’s embedded systems require more and more performance but they are still required to meet power constraints. Single processor systems can deliver high performance but this leads to high power consumption. One solution to this problem is to use a multiprocessor system instead which is able to provide high performance and at the same time meet the power constraints. The reason that such a system can meet the power constraints is that it can have a lower clock frequency than a similar single processor system. The focus of the project is to explore possibilities when developing new multiprocessor systems. The project makes a comparison of asymmetric multiprocessing (AMP) systems and symmetric multiprocessing (SMP) systems in terms of task management and communication between the processors. A comparison is made between the Advanced High-performance Bus (AHB) interface and the Advanced eXtensible Interface (AXI). The fixed priority and round-robin arbitration algorithms is also compared. The project also contains a practical part where a demo is developed to show that an inter-processor communication using exclusive access is possible to implement. The theoretical part of the project containing the comparisons result in good comparisons that can be used to get an overview of what to use when developing new Multiprocessor System on Chip (MPSoC) designs. The demo developed in this project failed to meet the requirement of having a fully functional spinlock. This problem can be solved in the future if new hardware is developed.
