4. Run Streamer.exe from the location
C:\Program Files (x86)\Cypress\EZ-USB FX3
SDK\1.3\application\cpp\streamer\x86\Release
. As shown in
Figure 3-36
, choose
256 as
Packets per Xfer
and 32 as
Xfers to Queue
from the dropdown list available on the
Streamer application.
Packets per Xfer:
A transfer is a collection of packets for one data set. A greater number of
packets per each transfer reduces the USB overhead and achieves higher data throughput.
Xfers to Queue:
This setting initiates multiple transfers and adds them to the task queue. This
reduces the latency between successive transfers on the host application side. Therefore,
queuing more transfers gives a higher data rate.
