The speed improvement formula expresses by Amdahl's Law is

• Speedup = 1 / ((1 - P) * (P / S))

• Speedup = 1 / ((1 - P) + (P / S))

• Speedup = 1 / ((1 + P) + (P / S))

• Speedup = 1 / ((1 - P) - (P / S))

The speedup of pipeline processing over a non pipeline processing is defined by the ratio

• nt_n / ((k + n -1 ) t_p )

• nt_n / ((k -1 ) t_p )

• nt_n / ((k + n +1 ) t_p )

• nt_n / ((k - n -1 ) t_p )
