vectors in VHDL 2

[Altera_Forum]

hi every body 

im new to vhdl i wanna write a code for this picture but for its N-scale http://i41.tinypic.com/35ksllh.png  so i need to have N vectors with different length.N is a parameter. how i should write the code?

just have an array of vectors to the maximum length, and only use the number of bits you need. Bits left unconnected will be removed by the synthesisor.

Another option is to build a recursive component that reduces the width of the input and output vector with each recursion.
