Electronic control system for automobile
InactiveUS20060259207A1Energy efficient ICTError detection/correctionElectronic control systemControl system
In an ECU, a flash ROM has a main storage area for storing a current version of an application program and a sub-storage area for storing update version program that includes updated points from the current version program. A rewriting tool executes program rewrite processing including: store processing of storing the update version program in the sub-storage area; and memory changeover processing in which, when the writing of the update version program in the sub-storage area has been done successfully, the sub-storage area where the storing of the update version program has ended is changed over to a new main storage area instead of a memory area currently being used as the main storage area. When the writing in the sub-storage area has failed, the changeover is not conducted.

InactiveUS20080235519A1Improve efficiencySpeech analysisUnauthorized memory use protectionGeneral purposeParallel computing
An object is to achieve improvement in efficiency in a case where encoding processing of data and encryption processing are executed in parallel with each other. A program of a first accelerator core out of multiple accelerator cores is reconfigured for encryption processing in order to perform encryption processing on encoded data. At this time, control is extended so that the time required for encoding processing of data for one frame and the total time of the program rewrite time for the first accelerator core and the time which the first accelerator core requires for implementing encryption processing of accumulated encoded data will be nearly equal to each other. The control is performed by a first general-purpose processor out of multiple general-purpose processors. By minimizing a wasted time during which hardware does not execute any arithmetic and logic operation, improvement in efficiency in a case where encoding processing of data and encryption processing are executed in parallel with each other is achieved.

Method and apparatus for accessing for storage system
InactiveUS20060146809A1Avoid data corruptionAvoid accessMultiplex system selection arrangementsCircuit switching systemsCheck pointCluster systems
Exclusive control is exercised on access to a storage apparatus in a cluster system conducting system changeover. If a system fault has occurred in an execution system, a heartbeat message to a stand-by system is interrupted. A cluster program in the stand-by system detects a fault in the execution system. The cluster program transmits a request to a path setting program in an FC-SW to change over a disk access path from the execution system. Upon receiving the request, the path setting program rewrites a path management table, intercepts the disk access path from the execution system, and transmits a result of the processing to the cluster program. Upon receiving the result, the cluster program starts a server program. The server program starts business processing from a check point at the time when the business processing is stopped due to occurrence of the fault in the execution system.

ActiveUS7360013B2Simple methodContinuous operationDigital computer detailsProgram loading/initiatingMicrocomputerProgram rewriting
A method of rewriting a flash EEPROM of an electronic control device for controlling a vehicle equipment via a microcomputer is proposed. The flash EEPROM stores a control program and a flash EEPROM rewriting program. The operation of the vehicle equipment is changed by changing the control program via a microcomputer. When receiving a control-program-rewriting command signal, data on an internal condition and state of connection of the microcomputer are memorized. Then, the control program is changed to the flash EEPROM rewriting program, so that the data are read according to the flash EEPROM rewriting program to control the microcomputer to operate in the same internal condition and state of connection thereof as before. Thereafter, the microcomputer rewrites the flash EEPROM with a new control program sent from outside. Therefore, the vehicle equipment can be continuously operated by a user during the rewriting mode.
