Abstract:
|
Multicore processors (CMPs) represent a good solution to provide the performance required by current and future hard real-time systems. However, it is difficult to compute a tight WCET estimation for CMPs due to interferences that tasks suffer when accessing shared hardware resources.We propose an analyzable JEDEC-compliant DDRx SDRAM memory controller (AMC) for hard real-time CMPs, that reduces the impact of memory interferences caused by other tasks on WCET estimation, providing a predictable memory access time and allowing the computation of
tight WCET estimations. |
