摘要： Methods, apparatus and software products are described for design-time data-assignment techniques for hierarchical memories, e.g., multi-banked memories in an essentially digital system as well as methods, apparatus and software products for run-time memory management techniques of such a system. Memory assignment techniques are described for assigning data to a hierarchical memory particularly for multi-tasked applications where data of dynamically created/deleted tasks is allocated at run-time. The energy consumption of hierarchical memories such as multi-banked memories depends largely on how data is assigned to the memory banks. Methods, apparatus and software products are described for design-time data-assignment techniques for hierarchical memories, e.g., multi-banked memories in an essentially digital system which improve a cost function such as energy consumption.
