Publication number: 20140215194Abstract: 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: ApplicationFiled: April 1, 2014Publication date: July 31, 2014Applicant: Renesas Electronics CorporationInventors: Hidemi OYAMA, Masanobu KAWAMURA, Takuya IKEGUCHI, Masanori MATSUMOTO, Hiroyuki KAWAJIRI

Patent number: 8671773Abstract: An electronic flow meter includes a magnetic sensor, phase-A and phase-B drivers, a phase-A comparator, a phase-B comparator, a two-phase encoder, and a rotational speed timer. The two-phase encoder determines a normal/reverse direction where the impeller is rotated based on event signals sampled by the phase-A and the phase-B comparators, respectively, causing a counter to count up or to count down according to the normal/reverse direction as determined, thereby outputting an event count signal. The rotational speed timer calculates a rotational frequency of the impeller from the event count signal outputted by the two-phase encoder and sets frequencies of respective sampling signals of the phase-A and the phase-B comparators at a time when the rotational frequency of the impeller is measured next, and respective drive periods of the phase-A and the phase-B drivers in accordance with the rotational frequency of the impeller as calculated.Type: GrantFiled: May 29, 2012Date of Patent: March 18, 2014Assignee: Renesas Electronics CorporationInventors: Yoshiharu Ono, Osamu Karino, Yoshihiro Shimizu, Yoshihiro Miyagawa, Hiroyuki Kawajiri, Takehiro Furukawa
