I/O Delays in RPvdsEx and OpenEx

When synchronizing processing circuits users should be aware of delays associated with the I/O of their hardware devices.

Users can synchronize outputs using delay components provided in RPvdsEx. See Delay Functions in the Component Reference section of the RPvdsEx Manual for more information.

I/O Component Delays

The table below provides a comparison of the delays associated with types of I/O and components.

I/O Type Component Delay Component Icons
Digital Input BitIn
WordIn		 2 samples BitIn and WordIn
Digital Output BitOut
WordOut		 3 samples BitOut and WordOut
Analog Input AdcIn
MCAdcIn		 device specific* AdcIn and MCAdcIn
Analog Output DacOut device specific* DacOut
RZ2 Data Pipe MCPipeOut/In 2 samples MCPipeOut and MCPipeIn
Requires PipeSource Component
Inter-DSP
zHop Pairs		 zHopOut/In
MCzHopOut/In
MCzHopPick		 2 samples zHop components

* See Device Delays for hardware specific delays.

For the bitmasks used to address byte and bit addressable digital I/O with the WordIn, WordOut, BitIn and BitOut components, see RZ Processor Digital I/O.
