Abstract: According to embodiments, a second control unit creates parity from information loaded into a volatile second memory. When shifting from a normal mode to a sleep mode, the second control unit stores the created parity and the information loaded in the second memory into a buffer of a non-volatile first memory, and issues a power supply shutdown request. A power supply circuit shuts down power supply to the second memory and the second control unit in response to the issued power supply shutdown request.

Abstract: Disclosed is an internal-combustion engine controller capable of improving emission characteristics at a start of an internal-combustion engine. When injection during an exhaust stroke is controlled in a port-injection engine, the engine controller ECU performs the first fuel injection during t1 to t2 according to a memory-based crank angle as illustrated in FIG. 12(b) at a fuel injection timing before determination of an actual stroke. Thus, the injected fuel has been introduced into a cylinder during the actual stroke. If fuel is not injected during t1N to t3N within the next exhaust stroke as denoted by the solid line, this causes misfire in the cylinder, so that the engine rotation at the start cannot be smooth. Thus, the ECU clears a finished fuel injection flag (F_INJ) at an incorrect crank angle storage determination timing (tJUD) as denoted by the dashed-dotted line, thereby capable of controlling the fuel injection.

Abstract: A stop control system for an internal combustion engine, which controls a stop position of a piston of the engine, is provided. An valve opening amount of an intake air flow rate control valve is determined based on the detected engine rotational speed and the detected crank angle after the ignition switch is turned off, and the intake air flow rate control valve is controlled so that the valve opening amount of the intake air flow rate control valve coincides with the determined valve opening amount. For example, the valve opening amount of the intake air flow rate control valve is determined according to the crank angle at the time the engine rotational speed decreases to reach a predetermined range, and the intake air flow rate control valve is controlled to be opened. With this control, the intake air amount of the engine is increased so that the stop position of the piston coincides with the desired position.

Abstract: The reliability of data is significantly increased without considerably increasing costs by performing minor data corrections within an information storage device and performing major error corrections in an information processing device. When a request to transfer user data for reading is issued from an information processing device, a control circuit transfers the user data and management data to an error detection circuit, which checks the user data for errors. If the user data contains no error, the control circuit notifies the information processing device that the user data can be transferred, and transfers it to the information processing device. If the user data contains errors, an X count error position and correction data calculation circuit uses the user data and the management data to calculate correction locations and correction data, and judges whether the correction locations are correctable.
