The disclosure relates to circuitry, systems, and methods for digital-to-analog conversion. In various examples, a corresponding circuitry may comprise a first digital-to-analog conversion circuit to provide a first analog output signal and a second digital-to-analog conversion circuit to provide a second analog output signal. The circuitry may comprise addition circuitry to provide a combined analog output signal from the first analog output signal and the second analog output signal. A first voltage reference circuit, connected with the first digital-to-analog conversion circuit to provide a first reference voltage and a second voltage reference circuit, connected with the second digital-to-analog conversion circuit to provide a second reference voltage may be provided. The first reference voltage and the second reference voltage may differ from each other.

Circuitry for converting a digital signal to an analog signal

A digital-to-analog converter (DAC) system includes a first DAC circuitry and a second DAC circuitry. An input splitter circuitry connected to the DAC system receives a first digital input code, and based on a value of the first digital input code, transfers the first digital input code to the first DAC circuitry for conversion to an analog output signal. The input splitter receives a second digital input code, and based on a value of the second digital input code, divides the second digital input code into a primary component and a secondary component, transfers the primary component to the first DAC circuitry for conversion to an analog output signal primary component, and transfers the secondary component to the second DAC circuitry for conversion to an analog output signal secondary component. An adding circuitry combines the analog output signal primary component and secondary component to provide a combined analog output signal.

Digital-to-analog (DAC) converter

A memory management circuit includes a direct memory access (DMA) channel. The DMA channel includes logic configured to receive a buffer of data to be written using DMA. The DMA channel further includes logic to perform bit manipulation in real-time during a DMA write cycle of the first buffer of data.

Bit manipulation capable direct memory access

An embedded system and method for controlling such are disclosed. The embedded system includes a direct memory controller comprising a plurality of channels, wherein a plurality of channel arbitration schemes are programmable, wherein the DMA controller is programmable to split a block data transfer on a specified channel into a plurality of separate data transfers, wherein a data transfer on a specified channel can be interrupted between separate data transfers of the data transfer.
