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.
摘要翻译：一种上下文切换方法，其能够通过转换多个寄存器文件的状态，切换上下文以及单独地恢复和存储上下文来迅速切换动态生成的任务的上下文和动态链接。也就是说，上下文切换方法包括：保持多个寄存器文件; 将多个寄存器建立为预取状态，当前状态和存储状态中的任何一个; 当上下文切换发生时，将多个寄存器文件的状态转换为预取状态，当前状态和存储状态中的任一个; 其特征在于，在所述预取状态下，确定存储器地址以读取随后由所述寄存器文件执行的下一个任务上下文，在当前状态下，执行具有所述寄存器堆的任务上下文和存储状态的任务，将文件注册到内存中。

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.

摘要： Provided is a method of managing memory in a multiprocessor system on chip (MPSoC). According to an aspect of the present invention, locality of memory can be reflected and restricted memory resources can be efficiently used by determining a storage location of a variable or a function which corresponds to a symbol with reference to a symbol table based on memory access frequency of the variable or the function, comparing the determined storage location and a previous storage location, and copying the variable or the function stored in the previous storage location to the determined storage location if the determined storage location is different from the previous storage location.
