A Software Managed Stack Cache for Real-Time Systems

WebCaching refers to the process of storing frequently accessed data in a temporary, high-speed storage system to reduce the response time of requests made by applications. Caching can help improve the performance, scalability, and cost-effectiveness of cloud applications by reducing the need for repeated data access from slower, more expensive storage systems. WebMay 1, 2000 · A practical, fully associative, software-managed secondary cache system that provides performance competitive with or superior to traditional caches without OS or application involvement is presented.

Webtime embedded systems can be vastly found. In a real-time system, the correctness of the system depends not only on its logical behavior but also on the time in which the computation is performed [Liu and Layland 1973]. The main distinction is be-tween soft real-time (SRT) and hard real-time (HRT) systems. In both, applications are WebStep 3 (continued): Set advanced-level tuning in the processor and BIOS with Intel TCC Tools.
