    v19 v20  
    2020 * I add a new result "5870_opt". It is obtained with a new optimized kernel. It boosts the performance ~ 18 %.

     22== Analysis of VLIW instructions == 
     23Our kernel is directly written in IL. After compilation into machine code for RV770, I analyze distribution of the generated VLIW instructions. Results are obtained with fglrx 8.65.4 (Catalyst 9.9) and CAL 1.4beta.
