摘要： The present invention provides a system for data mapping and storing in digital three-dimensional oscilloscope, wherein the fixed coefficients, which are calculated according the parameters and settings of a digital oscilloscope, are stored into a fixed coefficient memory CO RAM, the fixed coefficients are outputted to N fractional operation units through N−1 D flip-flop delay units to multiply with the acquired data x(n) and then be accumulated, thus N fractional calculus results are obtained. In this way, N fractional calculus results can be obtained by performing L/N fractional calculus operations. N fractional calculus results are sent to a signal processing and display module, in which they are converted into a display data through a drawing thread, and the display data are sent to LCD for displaying, thus the fractional calculus operation and display of a input signal in a digital oscilloscope is realized.

摘要： A method for blockchain-based time stamping for digital signature is disclosed. The method includes two participants: a signer who signs a message, a verifier who verifies the message. In the method, the signer obtains hash values of a certain number of latest confirmed blocks in blockchain, binds these hash values and the message together to be a new message. The signer then generates a signature of the new message and inserts identification data of this signature and the new message into a transaction of blockchain. This method ensures that the generation time of the signature is prior to the generation time of the block which contains the signature and, at the same time, is after the generation time of the blocks whose hash values are included in the signature, which produces an accurate time interval for the digital signature.
