    摘要: A timing generator generates the same timing signals even when the frequency of a reference clock is changed. The timing generator includes a data memory for storing the timing data formed of quotient data and fractional data, a counter for counting the number of reference clock pulses and producing a delay time expressed by the quotient data, an accumulator for accumulating the fractional data and generating a carry signal when the accumulated value exceeds the reference clock period where the carry signal is provided to a cycle delay circuit for delaying an output of the counter by one cycle, a number converter for converting the timing data based on a ratio of first and second reference clocks, and a complementary number for compensating a time difference between the first and second reference clock periods.

    摘要: A timing generator compensates the difference between the reference clock frequencies by converting the base number for generating the timing signals corresponding to the ratio of reference clock frequencies. The timing generator includes: a data memory for dynamically receiving the timing data through the software process to determine the time length of the timing signals where the timing data is formed of a quotient produced by a division of the time length by a time period of a reference clock and a fraction which is a remainder of said division; a counter for counting the number of pulses of a reference clock signal and generating an output signal when the number of counts of the pulse coincides with the quotient; an accumulator for accumulating the fraction data with the fraction data of previous cycle of the reference clock signal and generating a carry signal when the accumulated value exceeds the time period of the reference clock signal; a number converter which converts the timing data provided through the software process based on a first reference clock period Tn by a ratio of the first reference clock period Tn and a second clock period Tm; and means for providing a complementary number -Tm of the second reference clock period Tm to the accumulator.

    摘要: In an air-fuel ratio control with a learning control, a first correction values stored in a memory in correspondence to intake condition of a combustion engine and fuel injection time are renewed in response to an air-fuel ratio of mixture sensed in an exhaust of the combustion engine and a second correction value also stored in the memory is renewed in dependence on a difference between the first correction values stored in correspondence to the same intake condition. The first correction values are used to correct a basic fuel injection time determined by the operating condition, while the second correction value is used to correct an ineffective fuel injection time. Fuel is injected for an interval which is a sum of the corrected basic fuel injection time and the corrected ineffective fuel injection time.
