Miss post>>Code Challenge: optimize c function using labview icons. VI and c-code given!

[Kjell-E]

{Edit: Sorry, I did intent for this to go into the LabVIEW section.. although, you can execute all the code on RT targets, as it does not involve floating operatins.. you could do it on the FPGA too..

Hi!

To pat myself on the back while keeping an eye out to see if anyone out there can do it better, I'd like to post a quick challenge! -Mostly though, the tribute goes to these two:
Original Code: Ashley Roll
C-code Optimisations: Scott Dattalo
(LabVIEW Port: Kjell-Edmund Ims)

In the VI, I have posted the original C-code (open source, includes url's and references to original authors), as well as my adaptation of the c code. It is a CRC 16 implementation that is FAST on embedded electronics, such as PIC's.. it executes in just 17 instructions on the PIC, not to shabby!

I basically just "copied" the c-code straight off over to LabVIEW code, using built in LV functions for shifts and such, the reason this is so optimized already is just because the original author of the c-code did a very good job of optimizing it.

So, if you are bored, jump right in and see if you can do it better!!

I have attached both LV 7.1, LV 8 and a jpg file so everyone can participate. The jpg is relatively small, its not a complicated code to copy by hand.. 😉
