Dynamic Interrupt Controller and Conflict Management for Transactional Memory in Embedded System

In hardware transactional memory system, selecting an interrupt handling mechanism is the one of problems. To handle interrupts occur in transactions, all systems need special mechanisms but these require more hardware or software resources, so this is not acceptable to the embedded system that has limitations. In this paper, we proposed interrupt handling process and interrupt controller that distributes interrupts to proper core in the system. Then we present performance metrics for the system and how transactional memory policies affect to the metrics. Simulation results show that roughly 80% of interrupts that occur in transaction can be improved and eager conflict detection, polite and polka contention managements are proper polices for the proposed system.
