    摘要: A failed manifold pressure sensor is identified in a control apparatus having two manifold pressure detecting systems as a failsafe. A first comparing unit outputs an abnormal signal when a difference ΔP between manifold pressures PMa and PMb detected respectively by two sensors is larger than a threshold value DP. A manifold pressure estimating unit estimates the manifold pressure from the engine revolution Ne, a throttle opening PLP, and an atmospheric pressure PAa. The difference calculating unit calculates a difference ΔPMb between the detected manifold pressure PMb and the estimated manifold pressure PMcal. The difference calculating unit calculates a difference ΔPMa between the detected manifold pressure PMa and the estimated manifold pressure PMcal. A second comparing unit compares the difference ΔPMa and the difference ΔPMb in response to the aforementioned abnormal signal. The failed manifold pressure sensor is specified according to which one of the difference ΔPMa and the difference ΔPMb is larger.

    摘要: A computer-aided system and method is disclosed for designing an application specific integrated circuit (ASIC) whose intended function is implemented both by a hardware subsystem including hardware elements on the integrated circuit and by a software subsystem including a general purpose microprocessor also on the integrated circuit. The system also generates software instructions for use by the software subsystem. The system utilizes a knowledge based expert system, with a knowledge base extracted from expert ASIC designers, and thus makes it possible for ASIC's to be designed and provided quickly and economically by persons not having the highly specialized skill of an ASIC designer.

The transfer of signals in the direction parallel to the surfaces of the plates is performed by lead wires electrically interconnecting the light LSIs. The transfer of signals in the direction normal to the surfaces is performed by the light emitted and received by the light LSIs.
