Fault repair apparatus, fault repair method and storage medium storing fault repair program

摘要

Disclosed is a fault repair apparatus capable of reducing time which fault repair processing needs.;The fault repair apparatus according to an exemplary aspect of the invention includes, a detection unit that detects a fault in the integrated circuit being equipped with a memory storing configuration data (config-data), and a circuit element whose logic operation is defined by the config-data; and outputs fault information; a memory unit that memorizes a fault area specification table which correlates whether or not a description in the config-data related to the fault information exists in any of memory areas to identification information which identifies the memory area; a specification unit that specifies a failed memory area from the fault information and the fault area specification table; and a correction unit that, about the config-data stored in the failed memory area, detects and corrects error data which does not agree with an expected value.

主权项

1. A computer-implemented fault repair apparatus comprising:
a processor; a memory storing instructions to be executed by the processor by causing the processor to execute:
a detection unit configured to:
detect a fault in an integrated circuit, andoutput fault information related to the detected fault, wherein the integrated circuit comprises a circuit element and an updateable memory storing configuration data and wherein a logic operation of the integrated circuit is defined by the configuration data;a memory unit configured to store a table which indicates if a description in the configuration data related to the fault information exists in any of a plurality of memory areas included in the updateable memory and stores identification information identifying the memory area in which the description exists;a specification unit configured to specify a fault occurring memory area, which is the memory area in which the fault occurred, based on the fault information and the table; anda correction unit configured to, for the configuration data stored in the fault occurring memory area, detect and correct error data which is equal to an unexpected value on the basis of error detection and correction code data about the configuration data.
