I have some problem understanding the output of NEON simulator. The output generated is cryptic and there is no proper documentation for understanding the simulator output.

for example : enter image description here

In the above figure the 1st column's information is not clearly explained. What does lc mean? Sometimes the syntax given below doesn't match the data format in the table.

The code and data are at http://pulsar.webshaker.net/ccc/sample-55d49530 . I find some help at Some doubts in optimizing the neon code but it is not completely clear.

  • I think you also don't use `@` feature properly. – auselen Mar 25 '13 at 10:56

    It would also be useful for the community to know where the screenshot came from - clearly a simulator or profiler, but which one? – marko Mar 25 '13 at 19:57
  • pulsar.webshaker.net/ccc/index.php is the webpage that can be used for profiling NEON code – Aurum Mar 26 '13 at 10:39

It is not 'LC' it is '1C', i.e. one-C, meaning that instruction takes one cycle.
