How can I know the latency in a sub VI or routine (inline c node) in blackfin module?

[ACarpio]

Hi, I want to control a transceiver using a BF-537. The two principal taks are programming the transceiver and send/receive data from transceiver. These operation are development with sub-VIs, little routine in C using inline c node, etc. However, I need to know the lantency of each sub-VI or code writing in C; I need to know how much time use these elemnt to finished your function.

If anybody know How Can I to measure the lantecy, I will be grateful...!

Hello,

The easiest way to benchmark how long operations take on the Blackfin is to insert timing code in a sequence structure to directly measure the timing with the Tick Count function.  Bear in mind, of course, that adding this code will itself affect your timing somewhat.  Take a look at the example below to see what I mean - you could just repeat this for each operation you wanted to measure.
