摘要： A context switch method capable of promptly switching a context for a dynamically generated task and a dynamic link by converting a state of multiple register files, switching the context, and separately restoring and storing the context. That is, the context switch method includes: maintaining a multiple register files; establishing the multiple register to be in any one of a prefetch state, a current state, and a store state; converting a state of the multiple register files to be in any one of the prefetch state, the current state, and the store state when a context switch occurs; wherein, in the prefetch state, determining a memory address to read a next task context to be subsequently performed by the register file, in the current state, performing a task with the task context of the register file and in the store state, storing the register file in a memory.

摘要： A method, medium, and apparatus to effectively handle an interrupt in a reconfigurable array. In the method, the reconfigurable array pauses execution of an operation when an interrupt request occurs, and after storing register values of a register to be used for handling the interrupt request, an interrupt service is performed by select processing units of the reconfigurable array in response to the interrupt request. Upon completion of the interrupt service, the register values are restored, and the reconfigurable array resumes execution of the operation.
