In modern computers, memory hierarchies play a paramount role in improving the average execution time. However, this fact is not so important in real-time systems, where the worst-case execution time is what matters the most. System designers must use complex analyses to guarantee that all tasks meet their deadlines. As an alternative to making those(More)
Locking caches, providing full determinism and good performance , are a very interesting solution to replacing conventional caches in real-time systems. In such systems, temporal correctness must be guaranteed. The use of predictable components, like locking caches, helps the system designer to determine if all the tasks will meet its deadlines. However,(More)
Cache memories are crucial to obtain high performance on contemporary computing systems. However, sometimes they have been avoided in real-time systems due to their lack of determinism. Unfortunately, most of the published techniques to attain predictability when using cache memories are complex to apply, precluding their use on real applications. This(More)
A wearable fingertip based input interface software has been developed. High speed detection of fingertip position for maintaining real-time software capability, stable finger motion analysis as well as reliable direction pointing have been added to the real-time JAVA based foreground segmentation software. The developed interface system can be run on a(More)
