Patent number: 8051234Abstract: The present invention provides a technique capable of processing a plurality of interrupt causes sharing one interrupt request in different processors. An interrupt controller outputs an interrupt request when the interrupt request shared by a plurality of interrupt causes is notified. The interrupt request output by the interrupt controller is accepted by one of the processors. The processor accepting the interrupt request determines whether the interrupt cause that the processor must process has occurred, executes an interrupt processing when such interrupt cause has occurred, and notifies the generation of the interrupt request to another processor that processes another interrupt cause of the plurality of interrupt causes sharing the interrupt request when the relevant interrupt cause has not occurred.Type: GrantFiled: August 31, 2010Date of Patent: November 1, 2011Assignee: Renesas Electronics CorporationInventors: Hirokazu Takata, Naoto Sugai

Patent number: 6374353Abstract: A method of booting up an information processing apparatus is provided. An operating system is divided into a mini operating system (OS) module having a function of bootstrap and an OS main body module having functions other than the function of bootstrap. The mini OS module can be located in a boot block of a boot device, whereas the OS main body module can be located in a file system of the boot device. A firmware or F/W code module stored in a ROM loads the mini OS module into memory when booting up the information processing apparatus. The mini OS module then loads the OS main body module into memory and then initializes the OS main body module.Type: GrantFiled: March 3, 1999Date of Patent: April 16, 2002Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Atsushi Settsu, Noriyuki Baba, Naoto Sugai
