The XMC-SoftDAC-32F allows the output of waveforms at a continuous compounded rate of 500k samples per second. A state machine extracts the output data from a 1M word FIFO buffer. The buffer space is only used by the channels updated by the state machine (i.e., if only 16 channels use the FIFO, then each channel has about 64k samples). Writing to the FIFO supports DMA access, which allows high speed transfer rates to the board. The onboard state machine allows recycling the FIFO data to produce a continuous recurring waveform with no processor intervention once the data has been input to the FIFO. Additional information in the data words contains the destination channel as well as range and gain instructions for the state machine. These instructions allow smooth changes from one set of data to the next. This scheme also supports faster refresh rates on some channels compared to others.
