Hi, I'm trying to calculate de CPU load by access the performance counters in mips and I haved reading in the cp0 but my problem is that I cannot find documentation about the real meaning of these counters : 1.-LOG_PERF_CNT_NISSUE : ¿means cycle with no issue? 2.-LOG_PERF_CNT_SISSUE : ¿means cycle with issue? 3.-LOG_PERF_CNT_DISSUE: ¿means cycle with double issue? so CPU load will be == 2*100/(1+2) , in the period of time. any clue... thanks -- Please avoid sending me Word or PowerPoint attachments.
