System Design Flow

The Web browser receives one CDMA benchmark result at a time. Javascript is used to
convert the benchmark result into coordinates and update the graph. The graph
updates every time a new data point is received. The graph holds a maximum of 12
data points at a time. After the maximum has been reached, the oldest data point is
dropped and the newest data point is added.

In the benchmarking demonstration Web page, click

Stop Benchmark Graph

to stop

requesting benchmarking data. After this button is clicked, any pending requests are
completed and no additional data is requested.

12. When finished, in the XMD window enter:

XMD%

stop

XMD%

rst

XMD%

exit

Adding the AXI_CDMA with benchmarking cores to analyze performance from the base
MicroBlaze Processor Subsystem is completed.
