The performance and power consumption of mobile DRAMs (LPDDRs) depend on the configuration of system-level parameters, such as operating frequency, interface width, request size, and memory map. In mobile systems running both real-time and non-real-time applications, the memory configuration must satisfy bandwidth requirements of real-time applications, meet the power consumption budget, and offer the best average-case execution time to the non-real-time applications. There is currently no well-defined methodology for selecting a suitable memory configuration for real-time mobile systems. The worst-case bandwidth, average-case execution time, and power consumption of mobile DRAMs across generations have furthermore not been investigated.
