摘要： A dual-edge aware clock divider configured to generate an output clock based on the input clock and a ratio of an integer M over an integer N is disclosed herein. The frequency of the output clock is based on a frequency of the input clock multiplied by the ratio (M/N), wherein M may be set to a range up to N. The output clock includes M pulses within a sequence time window having a length of N periods of the input clock. The output clock includes one or more rising edges that are substantially time aligned with one or more rising edges and one or more falling edges of the input clock, respectively. The dual-edge aware clock divider is configured to generate the output clock based on inverted and non-inverted portions of the input clock. A hybrid clock divider including the dual-edge and single-edge aware techniques is provided.

摘要： Memory devices and methods utilize pipelines to process or control timing of commands received by the memory device. They may also use tracking circuitry configured to determine whether one or more of the commands are in the pipeline. The tracking circuitry includes an input counter configured to count commands entering into the pipeline and an output counter configured to count commands exiting the pipeline. Furthermore, the tracking circuitry includes comparison circuitry configured to compare values in the input counter and the output counter and to output a command-in-pipeline signal indicative of the one or more commands being in the pipeline when the values in the input counter and the output counter differ.

摘要： An electronic device (100) has a data storage device (120) for storing N data elements, the data storage device (120) comprising a first collection (122) of data storage elements (130). The first collection (122) of data storage elements (130) is accessible through an address decoder (140). In a shift register mode of the data storage device (120), the address decoder (140) is responsive to an address generator (160) comprising a modulo-N counter. Rather than having to shift data elements from one data storage element (130) to another, the address generator (160) generates a pointer to the data storage element (130) that contains the data element that is to be shifted out of the shift register. This has the advantage that the output of a predecessor data storage element (130) in a shift register need not be interconnected to the input of its successor. In addition, the amount of data traffic required during a shift is drastically reduced. The invention is particularly relevant to reconfigurable logic devices that use look-up tables for implementing shift registers.

摘要： Cross-channel interference can be a problem in multi-channel switched power systems. A multi-channel switched power converter is provided a reference count generator that generates a reference count signal that is commonly distributed to multiple, pulse width modulating (PWM) channels of the converter. The common reference count signal counts through a sequence of successive timing values. Events in each channel are scheduled relative to the common reference count. Examples of such events include the amplification or de-application of a driving voltage pulse to an inductive means of the channel and the taking of voltage and current measurement samples. Cross channel interference is avoided or minimized by scheduling or re-scheduling events in each active channel so that they do not occur simultaneously in potentially-interfering channels, for example the taking of a current measurement sample in one channel and the turning on of an inductance-driving voltage pulse is a second channel.
