Abstract: The next generation Global Positioning System (GPS) will have many new features. Also the infrastructure will be noticeably enhanced. This has directed us to consider a new dynamic memory management strategy for the next generation GPS. The distinctiveness of the suggested infrastructure is shifting elements of the GPS applications to the operating system with the objective of managing application data more efficiently. A key component of any GPS application is caching its data with the intention of preventing excessive memory accesses and allocations. The suggested infrastructure called 'Cache Based Dynamic Memory Management' - CBDMM - aims at moving the caching component from the GPS application to the embedded operating system of the GPS. The paper introduces CBDMM design, discusses its advantages and shows several encouraging benchmarking results.
