摘要： Provided are an apparatus for reconfiguring a mapping method and a scheduling method in a reconfigurable multi-processor system. A single function is mapped to a reconfigurable processor. When a task is created in the reconfigurable multi-processor system, a function of the task is dynamically mapped to a host processor or a reconfigurable processor, thereby removing temporal sharing between functions on the reconfigurable processor and thus reducing the number of times reconfiguration is performed. The overhead of the reconfigurable processor is minimized and the reconfigurable processor is optimized for a dynamic multi-application environment.

摘要： A multi-tasking method performs a plurality of tasks according to priority of each of the plurality of tasks. It is determined whether a resource that is to be used by a current task is being used by another task, a priority of the current task is compared to a priority of the task that is using the resource according to a result of the determination, and according to a result of the comparison, the priority of the task that is using the resource is increased to a highest priority of priorities of all tasks trying to occupy a CPU. Accordingly, conventional problems in the BPI and IIP schemes can be solved.
