请问手册中rate=0.03和MILLION CYCLES = 7843具体是什么含义呢?
源码中有rate的含义,可以查看源码。
case IJ2E_VCT_PARAM_TYPE_DOUBLE: // Numerical double
if (1 != sscanf (items[i+2], "%lf", &DoubleContent))
{
fprintf(fpErr, " Parsing error: Expected numerical value for Parameter of %s, found '%s'.", items[i], items[i+2]);
}
rate = DoubleContent;
break;
MILLION CYCLES是cpu cycles。比如C6678主频1.4GHz,就是1400 Million cycles。
