Abstract [en]

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.

Abstract [sv]

Dagens inbyggda system kräver mer och mer prestanda men de måste fortfarande klara av kraven kring strömförbrukning. System med en processor kan leverera hög prestanda men detta leder till hög strömförbrukning. En lösning till detta problem är att använda ett multiprocessorsystem istället som klarar av att leverera hög prestanda och samtidigt klara av kraven kring strömförbrukning. Anledningen till att denna typ av system klarar av kraven kring strömförbrukning är att de kan använda en lägre klockfrekvens än ett system med en processor. Fokuset på detta projektet ligger på att utforska möjligheterna som finns när nya multiprocessorsystem ska utvecklas. Projektet gör en jämförelse mellan asymmetriska och symmetriska multiprocessorsystem i termer av uppgiftshantering och kommunikation mellan processorerna. En jämförelse har gjorts mellan Advanced High-Performance Bus (AHB) gränssnittet och Advanced eXtensible Interface (AXI) gränssnittet. Fixed priority och round-robin algoritmerna för hantering av krockar mellan processorerna har också jämförts. Det finns även en praktisk del i projektet där en demo har utvecklats för att visa en fungerande kommunikation mellan processorer som använder funktionaliteten för exklusiv åtkomst till den gemensamma bussen. Den teoretiska delen av projektet som innehåller jämförelserna resulterar i bra jämförelser som kan användas när nya multiprocessorsystem utvecklas. Demon som har utvecklats i detta projekt misslyckades med att klara av kravet kring att ha ett fullt fungerande lås. Detta problemet kan lösas i framtiden ifall ny hårdvara utvecklas.
