The only reason I need 600 MHz now is to support the *#&^$& graphics bells and whistles of the bloated KDE desktop, although it does recompile EMC2 a lot faster. Also, HAL is a lot less efficient than the old direct connection between trajectory and motion of EMC1. Since I am not using software step generation, the processor is totally loafing. Even with all these inefficiencies, the entire servo calculation takes under 100 us, every ms. So, that is just 10% of the CPU. Jon |
