We studies the operational mode summary and mission profile (OMS (Operation Mode Summary) /MP (Mission Profile)) of several weapon systems and the naval ships. And then, several characteristics of OMS/MP and operating concept of SONAR system with grouping are analyzed, which is sub-weapon system of submarine. Finally, we proposed method of establishing OMS/MP of SONAR system not only the OMS or MP...
Although a data cache provides fast access latency, it degrades the timing predictability of real-time embedded systems due to misses which are difficult to predict. Scratch pad memory is accessed as fast as a data cache, but does not suffer from unpredicted misses thanks to its software-controlled mechanism. This study presents how scratch pad memory reduces data cache pollution and misses for preemptive...
Hardware-managed caches introduce large amounts of timing variability, complicating real-time system design. One alternative is a memory system with scratchpad memories which improve system performance while eliminating such timing variability. Prior work introduced the DARTS approach, which combines static allocation of data into scratchpad memories, with task scheduling for preemptive multi-threaded,...
