摘要： A D/A conversion circuit which can perform D/A conversion at high speed and with high precision is disclosed. The D/A conversion circuit comprises an analog reference power supply, an output buffer, a multiplexer, a pre-buffer, and a current changeover switch. The pre-buffer operates with a power supply voltage different from that of the analog reference power supply, and outputs a voltage substantially equal to an output voltage of the analog reference power supply. For a predetermined period after logic of digital data changes, the output voltage of the pre-buffer is supplied to the output buffer, and an input parasitic capacitor of the output buffer is charged/discharged. After the predetermined period elapses, the output voltage of the analog reference power supply is supplied to the output buffer. Therefore, a charging/discharging current of the input parasitic capacitor does not flow through the analog reference power supply, and fluctuation of the output voltage of the analog reference power supply can be suppressed.

摘要： An in-car-use multi-application execution device is provided that ensures safety while maintaining convenience by securing operation of a plurality of applications and suppressing occurrence of a termination process within a limited processing capacity without degrading a real-time feature. The in-car-use multi-application execution device dynamically predicts a processing time for each application, and schedules each application on the basis of the predicted processing time. If it is determined that an application failing to complete a process in a prescribed cycle exists as a result of the scheduling, a process is executed that terminates the application or degrades the function of the application on the basis of a preset priority order.
