Abstract: PROBLEM TO BE SOLVED: To provide a device and a method for shortening a memory processing time, when transferring digital data. SOLUTION: Concerning the device and the method for memory management at transfer of digital data, the device is composed of a first memory matrix (61) and a second memory matrix (62). Concerning the method, a bit column having a fixed value is added as a first column of a second memory row (64), a first bit row is copied as a second bit row according to the selection of an adding comparing selecting part and a selection to a decoding bit is performed, on the basis of the value of an element in a column (66) formed from the second bit row or on the basis of some other row formed from the second bit column.

Abstract: Methods, devices and a software product for generating a sinusoidal signal. If the desired frequency is higher than the upper limit, a coefficient is determined as a function of a multiple of the sampling rate. A sample of the first output sample sequence is determined as a linear combination of the coefficient and previous output samples. The first output sample sequence is decimated so as to generate the desired sinusoidal signal. If the desired frequency is lower than the lower limit, the coefficient is determined as a function of the multiple of the sampling rate. The sample of the first output sample sequence is determined as a linear combination of the coefficient and previous output samples. The first output sample sequence is multiplied so as to generate a second output sample sequence, which is decimated so as to generate the desired sinusoidal signal.

Abstract: Methods, devices and a software product for generating a sinusoidal signal of a desired frequency at a desired sampling rate. If the frequency is higher than the upper limit, a coefficient is determined as a function of the sampling rate and a sample of the first output sample sequence is determined as a linear combination of the coefficient and two previous output samples. The first output sample sequence is decimated by the sampling rate. If the frequency is lower than the lower limit, the coefficient is determined as a function of the sampling rate and the sample of the first output sample sequence is determined as a linear combination of the coefficient and two previous output samples. The first output sample sequence is multiplied so as to generate a second output sample sequence. The second output sample sequence is decimated by the sampling rate.
