Patent number: 8161362Abstract: Processed results are received when processors make compatible computations on data of a common object. A computation command signal is generated and fed to the processors in response to a start signal from any one of the processors so that the processors can make computations with different operation timings. Then, the results of the computations made by the processors are compared with each other. Thus, apparatus capable of small size, high performance and safety at the same time can be achieved by the above construction using the processors.Type: GrantFiled: June 7, 2006Date of Patent: April 17, 2012Assignees: Hitachi, Ltd., Hitachi Information & Control Solutions, Ltd.Inventors: Akira Bando, Shin Kokura, Takashi Umehara, Masamitsu Kobayashi, Hisao Nagayama, Naoya Mashiko, Masakazu Ishikawa, Masahiro Shiraishi, Akihiro Onozuka, Hiromichi Endoh, Tsutomu Yamada, Satoru Funaki
