Title:
プログラマブルデバイス、プログラマブルデバイスのリコンフィグ方法および電子デバイス
Document Type and Number:
Japanese Patent JP5699057
Kind Code:
B2
Abstract:
In the event of a software error, operations of a programmable device must be suspended while a configuration memory is being rewritten; however, with a system such as a communication device that will be significantly affected if the device is shut down, the system needs to be restored without suspending the operations. This programmable device is provided with: multiple control circuits; a comparison unit that compares outputs of the multiple control circuits so as to inspect for an occurrence of an error; a storage unit that stores internal states of error-free control circuits among the multiple control circuits when an occurrence of an error is determined by the comparison unit; a reconfiguration unit that reconfigures the control circuit in which the occurrence of the error has been determined by the comparison unit; and a control unit that inputs the internal states of the error-free control circuits, which are stored in the storage unit, to the control circuit in which the occurrence of the error has been determined by the comparison unit.
