摘要

Dynamically Reconfigurable Hardware (DRHW) platforms present both flexibility and high performance. Hence, they can tackle the demanding requirements of current dynamic multimedia applications, especially for embedded systems where it is not affordable to include specific HW support for all the applications. However, DRHW reconfiguration latency represents a major drawback that can make the use of DRHW resources inefficient for highly dynamic applications. To alleviate this problem, we have developed a set of techniques that provide specific support for DRHW devices and we have integrated them into an existing multiprocessor scheduling environment. In our experiments, with actual multimedia applications, we have reduced the original overhead due to the reconfiguration latency by at least 93.
