+// This option select version where RAW dependencies which leads
+// to hazards are not resolved in hardware, you need to schedule
+// instruction execution according to the pipeline structure

+// into fibo_limit variable and expects computed series in memory starting
+// at address fibo_series, the series has to be followed by at least
+// one zero element
+
