A DMA controller includes a built-in timing sequence generator that allows the DMA controller to trigger data movement periodically and/or non-equidistantly, without waking a CPU or other peripherals.

A touch sensor includes electrodes that are serially arranged and a processor with multiple input terminals. The electrodes are grouped into first, second and third groups of electrodes. Each electrode of the first group is coupled with a corresponding input terminal of the processor. The electrodes of the second group are sequentially coupled with the input terminals of the processor by way of odd numbered electrodes of the first group. The electrodes of the third group are sequentially coupled with the input terminals of the processor by way of even numbered electrodes of the first group. Each of the electrodes, other than the electrodes on the ends, is triggered simultaneously with at least one of its neighboring electrodes to provide sensed signals to the processor.

A system for prototyping an integrated circuit (IC) that has a mixed signal intellectual property (IP) core includes implementing the IP core using discrete programmable digital ICs and discrete analog ICs by partitioning the IP core into a digital IP portion and an analog IP portion.
