0.6
RRD Total = Basic time + (LengthLM)
Basic execution time
Length multiplier (LM)
52
2.5
RRW Total = Basic time + (LengthLM)
Basic execution time
Length multiplier (LM)
49
1.7
S For length = 1 and specified as a constant (e.g., S V0.2, 1)
Execution time
Otherwise,
Total execution time=Basic execution time +(LengthLM)
Basic execution time for all other operands
Length multiplier (LM) for all other operands
If the length is stored in a variable instead of being a
constant, increase the basic execution time by adding:

SBR Basic execution time 0
SCRE Basic execution time 0.37
SCRT Basic execution time 17
SEG Basic execution time 30
SHRB Total = Basic time + (LengthLM1) + ((Length/8)LM2)
Basic execution time (constant length)
Basic execution time (variable length)
Length multiplier 1 (LM1)
Length multiplier 2 (LM2)
76
84
1.6
4
SI Total = Basic time + (LengthLM)
Basic execution time
Length multiplier (LM) (local output)
Length multiplier (LM) (expansion output)
If the length is stored in a variable instead of being a
constant, increase the basic execution time by adding:
