A Software Managed Stack Cache for Real-Time Systems

Webtimes improve efﬁciency substantially compared to the ﬁxed policy of a hardware-managed cache [31]. Software-managed local stores are widely used in em-bedded systems, where they help improve performance and performance predictability, as well as reducing cost and power dissipation. However, they are rarely em-ployed in general-purpose systems. 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 bitter end coffee shop
