Patent number: 8265087Abstract: A gateway apparatus for performing transfer control of frame data between communication channels includes a routing map that stores ID information about the frame data and information about a communication channel that uses the ID information, and a search engine unit that routes the frame data to a transfer destination on the basis of the ID information of the frame data received and the routing map. The search engine unit does not transfer the frame data to the transfer destination when the ID information about the frame data received is ID information that is not used in the communication channel through which the frame data is received.Type: GrantFiled: October 26, 2007Date of Patent: September 11, 2012Assignees: Fujitsu Ten Limited, Fujitsu Semiconductor Limited, Renesas Electronics CorporationInventors: Kaoru Noumi, Susumu Nishihashi, Tomoyuki Katou, Yukio Ishikawa, Yasuyuki Umezaki, Hidetaka Ebeshu, Shigeo Koide, Yukio Fujisawa, Hiroaki Shimauchi

Patent number: 8122316Abstract: An error detector has a parity bit generator which generates error detection data for data strings sent from a CPU I/F to a memory, a parity checker which detects an error in the data strings output from the memory based on the error detection data, and a selector circuit which switchingly outputs the data from the parity bit generator and the data from a CPU which sends diagnostic data. While the selector circuit is switched to output the data from the CPU, based on the error detection data output from the selector circuit, the error detector conducts a failure diagnosis of error detection functions including at least one of the parity bit generator and the parity checker.Type: GrantFiled: October 25, 2007Date of Patent: February 21, 2012Assignees: Fujitsu Ten Limited, Fujitsu Semiconductor Limited, Renesas Electronics CorporationInventors: Kaoru Noumi, Susumu Nishihashi, Tomoyuki Katou, Yukio Ishikawa, Yasuyuki Umezaki, Hidetaka Ebeshu, Shigeo Koide, Yukio Fujisawa, Hiroaki Shimauchi

Patent number: 7801173Abstract: A communication conversion apparatus achieve efficient conversion without conversion delay and converts messages that effect communication with different communication protocols and schedules. In a message conversion apparatus that performs message conversion of different communication protocols, a routing circuit and a scheduler circuits that perform scheduling of the different communication protocols are separately provided. And time-triggered scheduling and event-triggered scheduling are separately performed. Conversion of FlexRay and CAN messages can be efficiently implemented.Type: GrantFiled: December 12, 2006Date of Patent: September 21, 2010Assignee: Fujitsu Ten LimitedInventors: Tsuyoshi Takatori, Kaoru Noumi, Susumu Nishihashi, Tomohide Kasame, Yukio Ishikawa, Satoshi Fukui, Kokoro Hayashi
