RE: [microblaze-uclinux] application's execution time

["Brettschneider Falk" <fbrettschneider@xxxxxxxxxxxxxxx>]

Consider matrix multiplication has a cubic computation time using the Gauss algorithm. 
Following this: if a 6x6 matrix (computation time 6^3) takes 0.01 sec, a 100x100 matrix (computation time 100^3) will aproximately 50 sec. If you also consider the cache issue, I can imagine a few hours of computation.
