摘要:
A circuit arrangement comprises an input circuit for reading in a serial data stream, which comprises a plurality of useful data bits, and for reading in a piece of information which indicates the start of the serial data stream. The circuit arrangement also comprises a data processing circuit for removing at least one useful data bit from the read-in, serial data stream. The data processing circuit is designed such that it removes the at least one useful data bit at a prescribed position after the start of the serial data stream. The circuit arrangement also comprises a first output circuit for outputting the read-in, serial data stream for the omission of the at least one removed useful data bit.

Representative implementations of devices and techniques provide analog to digital conversion of analog inputs. A multistage comparator using a feed-forward technique can provide noise shaping of conversion errors. For example, the comparator may feed a conversion error forward from a first stage to a next stage of the multistage comparator.

A method and apparatus for regulating a dc-dc converter wherein a plurality of switches are arranged with respect to an energy storage device and an output capacitor. An impedance of one or more of the plurality of switches may be adjusted by altering a non-zero voltage provided to the one or more of the plurality of switches, the altering may be based on a slope control signal output by a multiplexer that receives a signal representing a conductance value of the one or more of the plurality of switches.

A circuit arrangement includes a plurality of functional units each of which comprises a plurality of data processing modules and a local controller. The plurality of data processing modules run a common system clock and are connected by a streaming data bus running a handshake-type streaming data transfer protocol. A profiling module of the circuit arrangement assesses control signals tapped at predefined interfaces of the streaming data bus during real time operation, for determining link performance and communication patterns for profiling and debugging purposes, and hence constitutes a simple and low cost approach for assessing intra-component and inter-component link performance and communication patterns on large SoCs. A method for profiling data flow for use in such a circuit arrangement is also provided.
摘要:
In one implementation an output signal of an oscillator is varied to be within a desired frequency band with respect to a reference signal, the output signal having a plurality of phases. The implementation may include comparing the output signal with the reference signal, counting falling edges about each phase of the number of phases in a predetermined time period and summing to define a count output; comparing the count output with a product of the number of phases of the output signal and the factor to define a comparison, generating a control signal based upon the comparison, and inputting the control signal to the oscillator to alter the output signal thereof.
