Figure 26: Pulse generator parameters. 

PulseGenGranularity

: Sets the pulse generator main timing resolution. The x1 resolution 

is in microseconds. The following four granularity steps are possible: x1, x10, x100, x1000 
(x1000 is equal to 1ms timing resolution). 

PulseGenWidth

: Sets the value of the pulse width in microseconds. 

PulseGenPeriod

: Sets the value of the pulse period in microseconds. 

PulseGenNumPulses

: Sets the number of pulses generated by the Pulse Generator. 

PulseGenMode

: Sets the Pulse Generator to generate either a continuous sequence 

(Continuous) or a discrete number of pulses (NumPulses).  

PulseGenEnable

: Enables the pulse generator. 

4.7.11 Transport Layer Control 

The Transport Layer Control provides read-only status information on each Streaming 
Interface Register Map (SIRM). The SIRM registers describe the transfers expected from 
the host side software. 
 

 

Figure 27: Transport layer control. 

PayloadSize

: Provides the number of bytes transferred for each image on the stream 

channel, including any end-of-line, end-of-frame statistics, or other stamp data.
