sorter in vhdl

kaz,be patient to make me understand the code

you consider in the code that addresses(duration) is a continuous values ,ok

if there is not a value in the successive address it put a zero in content of ram (corresponding to this empty address) its wright or not??

but the reverse happens i.e i have a discrete values.

and i have a question to you if i want to separate the codes and the addresses that output ascending i.e the codes ordered in output

and the corresponding in another output because i will use the codes that ordered to count the distances that we done before

i hope you understand me well
