Implementation your algorithm using VHDL under Quartus. You are free to select the structural hierarchy of the implementation; the implementation could be behavioral, structural, or a mixed implementation.

input .

x - the abscissa at which the linear interpolation is to be evaluated

xi[]- the arrays of data abscissas

yi[]- the arrays of data ordinates

imax- size of the arrays xi[] and yi[]

output .
