1.8 INTERNAL DETAILS
You can investigate the internal details of the demonstration by going to the front panel Window menu
and opening the block diagram (Show Block Diagram):
You will see that the diagram is made up from two frames which will execute from left to right. The left
frame is responsible for loading the application into the DSP. It uses the LOAD instrument which is given
the name of the application. The only output from LOAD is a boolean signal that is true should an error
occur while sending the application to the Sundance hardware; this will cause the demonstration to stop.
The right frame is the body of the demonstration. It is a loop that continually requests two streams of data
from the DSPs and displays them. Each stream is made up of arrays of integers brought in through the
INT32 instruments. Each of these instruments is given an integer that selects the number of the DSP's
output port that has been specified in PARS as presenting the data. In this example the DSPs use only two
output ports, 1 and 2. The output from the INT32 instruments will be arrays of integers. The frame also
implements the STOP button.
