Patent number: 10007623Abstract: 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: May 19, 2016Date of Patent: June 26, 2018Assignee: Renesas Electronics CorporationInventors: Hidemi Oyama, Masanobu Kawamura, Takuya Ikeguchi, Masanori Matsumoto, Hiroyuki Kawajiri

Publication number: 20170134099Abstract: An optical receiver module that receives a wavelength-multiplexed optical signal is disclosed. The optical receiver module includes a first lens, an optical de-multiplexer, second lenses, and photodiodes. The first lens forms a beam waist of the wavelength-multiplexed optical signal output therefrom. The optical de-multiplexer de-multiplexes the wavelength-multiplexed optical signal into optical signals depending on wavelengths thereof and is installed so as to make optical paths for respective optical signals different from each other. The second lenses concentrate the optical signals onto the respective photodiodes. In the optical receiver module, the beam waist of the wavelength-multiplexed optical signal is set in a halfway between a longest path and a shortest path from the first lens to the second lenses.Type: ApplicationFiled: November 9, 2016Publication date: May 11, 2017Inventors: Hiroshi Hara, Masanobu Kawamura, Takahiro Saito
