摘要： An embedded control system capable of ensuring precision in arithmetic with data in the floating-point format and also avoiding a shortage of the storage area of a memory is provided.
According to an embedded control system in the present invention, when discrete data in the floating-point format is stored in a read-only memory 3, the discrete data in the floating-point format is converted into data 10; 28 in a significand-reduced floating-point format before being stored. Here, a significand-reduced floating-point number is a number obtained by deleting low-order bits of the significand of a floating-point number. Further, an interpolation search is performed using discrete data, the discrete data in the significand-reduced floating-point format stored in the read-only memory 3 is brought back to the discrete data in the floating-point format before an interpolation search being performed.

摘要： An electronic control apparatus has a memory (16) which stores a map consisting of a set of map points and corresponding set of map values, with the map values representing respective physical quantity values, and at least one of the sets of map points and map values being stored as fixed-point representation data. When a map point is specified, the apparatus obtains a corresponding physical quantity value by converting fixed-point data of the map to floating-point representation, then using a floating-point arithmetic unit (14) to perform an interpolation calculation using the converted data.

摘要： The invention relates to a codifying and storing method for membership functions (MF) representing a membership degree (α) of fuzzy variables (x) defined within a universe of discourse (U.d.D.) which is discretized into a finite number of points (n). The membership functions (MF) are quantized into a finite number of levels (p) corresponding to a finite number of membership degrees, and are stored by means of a characteristic value of each sub-set of values of fuzzy variables (x) having for their image the same value of the membership degree (α) corresponding to one of said levels.
The invention further relates to a method for calculating the value of the membership degree of a fuzzy variable defined within a universe of discourse (U.d.D.) discretized into a finite number of points (n) with reference to a membership function (MF) thereof, as well as to a circuit (10) for calculating the membership degree (α) of a fuzzy variable (x) with reference to a membership function (MF) thereof.

摘要： A digital FM demodulation circuit which samples an input analog FM signal and digitally detects the sampled input signal has an arctangent circuit into which a second signal that is delayed from the sampled input signal by a constant time, and a third signal that is different in phase by 90 degrees from the second signal are input, and which outputs a corresponding arctangent value based on a result of a division of the two input signals. The arctangent circuit has: roundoff means for sequentially rounding the division result to one of plural typical values; and a ROM address unit for performing a control in which an arctangent value corresponding to the rounded typical value is selected from a ROM table containing arctangent values of the typical values, and the selected arctangent value is output.

摘要： Pre-defined driving profiles for the distinct phase-windings of an electronically controlled brushless motor, are continuously reconstructed for each switching phase and forced in the form of a drive current or voltage on the respective windings, in synchronism with a signal indicative of the rotor position, from just a first complete sequence and at least a first sample of the successive sequence of a number of sequences, each of N samples, equal to number of switching phases of the motor, in which is divided a complete digital pre-defined profile. The digital samples are stored in a nonvolatile memory (M1) and are scanned at a continuously regulated clock frequency and with varying order and direction of scan for reconstructing the instantaneous driving profiles for all the windings.
