SYSTEMS AND METHODS FOR MANAGING CACHE REPLACEMENT

A method of managing load units of executable instructions between internal memory in a microcontroller with multiple bus masters, and a non-volatile memory device external to the microcontroller. A copy of the load units are loaded from the external memory device into the internal memory for use by corresponding bus masters. Each load unit is with a corresponding load entity queue and each load entity queue is associated with a corresponding one of the multiple bus masters. Each load entity queue selects an eviction candidate from the associated copy of the load units currently loaded in the internal memory. Information identifying the eviction candidate for each load entity queue is broadcasted to all load entity queues. The eviction candidate is added to a set of managed eviction candidates if none of the load entity queues vetoes using the eviction candidate. 一种在具有多个总线主控器的微控制器中的内部存储器与所述微控制器外部的非易失性存储器装置之间管理可执行指令的加载单元的方法。将所述加载单元的副本从所述外部存储器装置加载到所述内部存储器中以供对应总线主控器使用。每个加载单元与对应加载实体队列相关联，并且每个加载实体队列与所述多个总线主控器中的对应一
