Instruction cache optimizations in embedded real time systems
... corresponding time deadlines, while no timing constraint is required in generalpurpose computer systems Real- time systems that have timing constraint can be classified into two types, soft real- time systems ... and hard real- time systems In soft real- time systems, the timing constraint is elastic Miss of the deadline in soft real- time systems only results in loss of QoS but not the failure of systems ... Thus, cache partitioning can be used to eliminate the inter-task cache interference in multitasking real- time systems or inter-core cache interference in multi-core processors with shared cache...
