Patent ID: 7882387

Claim:
A reconfigurable device comprising: a plurality of component processing elements each reconfigurably constructed to perform a function in accordance with configuration information; a generating device adapted to generate an interrupt signal when an error happens in one of the plurality of component processing elements; and a processor, external to the plurality of component processing elements, adapted to detect the interrupt signal, to mask the interrupt signal when the interrupt signal is detected, and to make a judgment as to whether the error affects an output of the reconfigurable device based on the configuration information of said plurality of component processing elements, wherein some of the component processing elements are adapted to perform functions different from other of the component processing elements, and wherein a change of the configuration information causes a change in function performed by the reconfigurable device; wherein said processor is adapted to determine whether an output of a second component processing element that is a destination to which is outputted an output of a first component processing element in which the error has been generated is affected by the output of the first component processing element and whether the output of the second component processing element is outputted to an outside of the reconfigurable device, and wherein in a case where it is determined that the output of the second component processing element is affected by the output of the first component processing element and is not outputted to the outside of the reconfigurable device, said processor is adapted to determine whether an output of a third component processing element that is a designation to which is outputted the output of the second component processing element is affected by the output of the second component processing element and is outputted to the outside of the reconfigurable device.
