    摘要: There is provided an instruction supply unit 20 for generating addresses for each instruction when an interrupt occurs, from an interrupted instruction until an instruction to be executed later by the number of instructions contained in a delay slot of the instruction an interrupt control unit 50 for storing each address thus generated, and an instruction executing unit 30 for successively reading out each of the stored addresses from the address of the interrupted address after the interrupt processing is completed. The instruction executing unit 30 executes a branch instruction to the address which is first read out. Thereafter, with respect to the addresses which are read out secondly and subsequently, if the address is the branch destination address of the branch instruction, the instruction executing unit 30 executes the branch instruction to the address, and if the address is not the branch destination address, it executes an NOP instruction. Accordingly, even when the instruction length is not fixed, the interrupt can be accurately processed.

    摘要: An information processor operating with a battery writes data which exists in a register of a CPU at that time into a predetermined stack area for transfer of an RAM when a suspend command is received in the normal operation state of the processor and shifts to the suspended state that the power supply to the minimum circuit components including the RAM is maintained and the power supply to the other circuit components is stopped. When insufficient power of the battery is detected in the suspended state, the information processor is started temporarily so as to automatically transfer and store the data in the RAM into a storage device using a non-volatile memory device.

    摘要: A failure diagnosis apparatus for an exhaust pressure sensor for detecting the exhaust pressure in an exhaust gas recirculation passage which connects an exhaust passage and an intake passage of an internal combustion engine. A first preliminary determination that the exhaust pressure sensor is normal, is made when the engine is in a predetermined low load operating condition and a difference between the detected exhaust pressure and the atmospheric pressure is equal to or less than a first determination threshold value. A second preliminary determination that the exhaust pressure sensor is normal, is made when the engine is in a predetermined high load operating condition and the difference between the exhaust pressure detected by the exhaust pressure sensor and the atmospheric pressure is equal to or greater than a second determination threshold value. A final determination that the exhaust pressure sensor is normal, is made when both of the first and second preliminary determinations are made.

    摘要: The display driver includes: a display data compression circuit; a recording circuit; a display data decompression circuit; and an output circuit. Further, the display driver is provided with a compressibility setting circuit. The display data compression circuit has the function of compressing the display data according to a compressibility set by the compressibility setting circuit. With the display driver arranged like this, the power consumption can be reduced by increasing the compressibility for a displayed image such that the image quality is not noticeably deteriorated even with the compressibility increased. Further, for the displayed image such that the image quality is noticeably deteriorated with the compressibility increased, a sufficient image quality after data decompression can be secured by lowering the compressibility.
