摘要:
A method of transmitting data between processors, including: establishing and storing an encoding method for each area of virtual address space of a first processor in a predetermined storage device; determining an area of virtual address space corresponding to data to be transmitted to a second processor; and determining the encoding method corresponding to the determined area of the virtual address space with reference to the storage device and transmitting the data to the second processor by using the determined encoding method.
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.

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:
Memory mapping in small units using a segment and subsegments is described, and thus it is possible to control a memory access even using a small amount of hardware, and it is possible to reduce costs incurred by hardware. Additionally, it is possible to prevent a memory from being destroyed due to a task error in the multi-processor system.
