Memory management systems and methods for embedded systems

摘要

Methods and systems are provided for managing static memory associated with software of an embedded system. The method includes performing one or more steps on one or more processors. The steps include selectively assigning memory objects to static memory segments based on access of the memory object by the software; managing data of the memory segments based on the assigning; and selectively restoring the data of the memory segments based on the managing.

1. A method of managing static memory for software of an embedded system, comprising:
performing on one or more processors,
when compiling the software, selectively assigning memory objects to one of adjacent and non-adjacent static memory segments based on access of the memory objects by the software;managing data of the memory segments based on the assigning; andselectively restoring the data of the memory segments based on the managing, wherein the selectively assigning the memory objects comprises: generating a simultaneous access graph; determining an allowable neighbors graph based on the simultaneous access graph; determining a minimum cost layout from the allowable neighbors graph; and selectively assigning the memory objects based on the minimum cost layout.
