7.1.1.2 ii_quixote_dac

Supported Platforms: Quixote

Description:

This component is an interface between the Quixote application logic and the DAC and

its external FIFO. The external FIFO is 32K samples.

The component controls the flow of samples from the internal FIFO to an external FIFO,

then on to the DAC itself. The data flows on the basis of the trigger and moves the

collected samples from the internal FIFO. The level of the internal FIFO may be used to

signal when space is available for more samples.

An underflow error flag indicates when the DAC trigger was true and a rising edge of the

DAC clock happened yet no data was available in the external FIFO for that DAC

sample.
