Provided is a method of managing a configuration memory of reconfigurable hardware which can reconfigure hardware according to hardware configuration information. The method includes: determining at least one slot capable of currently storing the hardware configuration information on the basis of the states of a plurality of slots of the configuration memory; and storing hardware configuration information, which is stored in an external memory, in the determined at least one slot capable of currently storing the hardware configuration information. Accordingly, memory utilization can be improved even in dynamic environment such as data dependent control flow or multi-tasking.

A unified memory apparatus for a reconfigurable processor and a method of using the unified memory apparatus are provided. The unified memory apparatus includes: a first memory to store data; and a second memory to store configuration information used to reconfigure a system for a processor to perform a predetermined function, wherein the first memory and the second memory are physically unified in a unified memory. Thus, a memory space can be efficiently used according to data and size of configuration information.

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.

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.

Provided are a load balancing method and a load balancing apparatus in a symmetric multi-processor system. The load balancing method includes selecting at least two processors based on a load between a plurality of processors, from among the plurality of processors, migrating a predetermined task stored in a run queue of a first processor to a migration queue of a second processor, and migrating the predetermined task stored in the migration queue of the second processor to a run queue of the second processor. Accordingly, a run queue of a processor is not blocked while migrating a task, an immediate response of the run queue is possible, and a waiting time of a scheduler is reduced. Consequently, the scheduler can speedily perform context switching, and thus performance of the entire operating system is improved.

A context switching method, medium, and system with a reconfigurable processor. The context switching system include a reconfigurable processor reconfiguring a program according to reconfiguration information and executing the reconfigured program, a central processing unit outputting a load command for sequentially loading reconfiguration information required for a plurality of tasks, in order to control the plurality of tasks, a reconfiguration information selecting unit selecting reconfiguration information for context switching, a reconfiguration information loading unit receiving the load command from the central processing unit, and loading reconfiguration information corresponding to the load command from a memory, and a plurality of reconfiguration information storage units storing the reconfiguration information loaded by the reconfiguration information loading unit. Accordingly, by pre-loading reconfiguration information which is required many times while context switching is performed, it is possible to quickly perform context switching and perform multitasking with a small overhead.
