Abstract

Memory Mapper is a software testing tool for measuring test coverage and revealing the locations of unexercised code branch paths. During a memory fetch in the processor main memory, a corresponding bit in the Mapper Memory is set. After applying test cases to the program under test, Memory Mapper is checked. Any non-set bit in the Memory Mapper indicates an unaccessed location.
