Memory-Map Selection for Firm Real-Time SDRAM Controllers

A modern real-time embedded system must support multiple concurrently running applications. To reduce costs, critical SoC components like SDRAM memories are often shared between applications with a variety of firm real-time requirements. To guarantee that the system works as intended, the memory controller must be configured such that all the real-time requirements of all sharing applications are satisfied. The attainable worst-case bandwidth, latency, and power of the memory depend largely on memory map configuration. Sharing SDRAM amongst multiple applications is challenging, since their requirements might call for different memory maps.
