Research on Memory Access to Un-aligned Addresses Exception Based on SPARC
摘要
Abstract
Exception handling strategy is a very important indicator in evaluating reliability level of embedded system,especially in the field of war industry,space industry and so on. Based on space flight standard CPU AT697F and real time operating system VxWorks,an-alyze the VxWorks exception handling strategy for SPARC,then illustrate register window mechanism of SPARC V8 architecture in detail and special implementation of this mechanism combined with VxWorks. Based on this,introduce an exception handling strategy according to SPARC V8,and implement the exception handling function to solve memory access to un-aligned addresses exception,improving the reliability of the system effectively.关键词
