A pipelined ADC that does not wait for the residue of a signal to settle to be delivered to the next stage of the pipeline, and thus passes signals to subsequent stages at faster than conventional speeds.

Systems, methods and devices for validating and performing operations on homomorphically encrypted data are described herein. The methods include securely transmitting and extracting information from encrypted data without fully decrypting the data. A data request may include an encrypted portion including a set of confidential data. One or more sets of encrypted comparison data may be then retrieved from a database in response to the data request. The encrypted set of confidential data from the data request is then compared with each set of encrypted comparison data using one or more homomorphic operations to determine which set of encrypted comparison data matches the encrypted set of confidential data. If there is a match, this validates the set of confidential data. An encrypted indicator is then generated indicating success or failure in validating the set of confidential data, which may then be forwarded to a party associated with the data request.

There is provided an apparatus that includes input circuitry to receive input data and output circuitry to output a sequence of instructions to be executed by data processing circuitry. Generation circuitry performs a generation process to generate the sequence of instructions using the input data. The sequence of instructions comprises an indirect control flow instruction having a field that indicates where a target of the indirect control flow instruction is stored. The generation process causes at least one of the instructions in the sequence of instructions to store a state of control flow speculation after execution of the indirect control flow instruction. The at least one of the instructions in the sequence of instructions that stores the state of control flow speculation is inhibited from being subject to data value speculation by the data processing circuitry.

The invention provides a vectorized representation method of a software source code. The vectorized representation method is an AST-based neural network which is a hierarchical vector representation method comprising the following implementation steps: step 1-1, converting an original software source code into an AST at the lowest layer, and then further dividing the AST according to source code statements to acquire a smaller statement tree sequence, wherein statement trees in the statement tree sequence are different in sequence, and the statement tree sequence is consistent with an original statement sequence; step 1-2, encoding the statement trees into statement vectors e1, e2, . . . , et by a recursive neural encoder; step 1-3, enabling an acquired statement vector sequence to pass through a bidirectional recurrent neural network layer to extract dependency features between statements; and step 1-4, sampling multi-dimensional features of all time steps of the bidirectional recurrent neural network layer through a pooling layer to acquire a final vector representation.

A skip behavior analyzer is part of a media delivery system that allows for unbiased A/B testing of a plurality of versions of a song. The media delivery system stores a plurality of versions of a song and randomly selects, for each requesting device, a version of the song to associate with that device. Each time the device requests the song, thereafter, the media delivery system will provide the same version of the song for consistency. The media delivery system then gathers song play and skip information, calculates the differences in distribution of the skip behavior, and provides the skip information to allow a music composer to better determine which version of a song is more popular and why that is so.
