A digital interface circuit includes a queue block configured to be coupled between an analog-to-digital converter (ADC) and a Direct Memory Access (DMA) controller of a processor, where the queue block comprises a command buffer and is configured to: receive a first command from the DMA controller; store the first command in the command buffer; modify the first command in accordance with first control bits of the first command to generate a modified first command; and send the modified first command to the ADC.

Digital interface circuit for sequencing analog-to-digital converter

An embedded system includes a peripheral and system-on-a-chip executing virtual machines and a hypervisor. The peripheral includes a crossbar circuit receiving digital sensor signals and selectively outputting the digital sensor signals to different outputs, queue circuits each receiving a different one of the digital sensor signals from the crossbar circuit, and queue protection circuits associated with the queue circuits and selectively permitting access to one of the queue circuits by the virtual machines. The hypervisor controls the queue protection circuits to set which of the virtual machines may access which queue circuits. A sensor protection circuit selectively permits reading of the digital sensor signals from the crossbar circuit by the queue circuits. The hypervisor controls the sensor protection circuit to set which of the queue circuits may access each of the digital sensor signals from the crossbar circuit.
