Patent number: 8219731Abstract: Provided are a data processor, and a control system, in which an interrupt controller and an event link controller are adopted. The event link controller responds to a generated event signal to output a start control signal for controlling start of an operation of a circuit module. The circuit module is able to generate an event signal. The event link controller generates the start control signal according to the correspondences between event signals and start control signals which are defined by event control information. The links between the event signals and start control signals can be prescribed by the event control information. Therefore, operations of circuit modules prescribed by such links can be controlled sequentially. The control neither involves save and return processes by CPU as in the interrupt processing, nor needs priority level control as executed on competing interrupt requests.Type: GrantFiled: November 1, 2011Date of Patent: July 10, 2012Assignee: Renesas Electronics CorporationInventors: Hidemi Oyama, Masanobu Kawamura, Takuya Ikeguchi, Masanori Matsumoto, Hiroyuki Kawajiri

Patent number: 6820179Abstract: A semiconductor device which has an internal circuit for performing a circuit operation corresponding to a signal inputted or outputted through an input/output interface circuit adapted to a serial bus. The semiconductor device has a non-volatile storage circuit for storing identification data. Internal identification data stored in the non-volatile storage circuit is compared with external identification data included in an input signal supplied through the serial bus by a comparator circuit. A control circuit is responsive to a match detecting signal generated by the comparator circuit to perform a circuit operation corresponding to an input signal subsequently supplied through the serial bus to change the internal identification data stored in the non-volatile storage circuit.Type: GrantFiled: December 4, 2001Date of Patent: November 16, 2004Assignees: Hitachi Hokkai Semiconductor, Ltd., Renesas Technology CorporationInventors: Nobuharu Kobayashi, Masanobu Kawamura, Toru Ishida, Masato Momii, Naoki Fujita
