Enhanced Queued Analog-to-Digital Converter (eQADC)
31.1
Introduction
The enhanced queued analog-to-digital converter (eQADC) provides accurate and fast conversions for a
range of applications. The eQADC provides a parallel interface to a single on-chip analog-to-digital
converter (ADC). The on-chip ADC is architected to allow access to all the analog channels.
The eQADC transfers commands from multiple command FIFOs (CFIFOs) to the on-chip ADC. The
block can also receive data from the on-chip ADC into multiple result FIFOs (RFIFOs), in parallel to and
independently of the CFIFOs. The eQADC supports software and external hardware triggers from other
blocks to initiate transfers of commands from the CFIFOs to the on-chip ADC. It also monitors the fullness
of CFIFOs and RFIFOs, and accordingly generates DMA or interrupt requests to control data movement
between the FIFOs and the system memory.
