NAT on Cisco router

I want to have a one to one NAT on a cisco router.
e.g Inside subnet NAT to outside subnet.
Each inside address will be NAT to one outside address. NAT to 172.16.254.x NAT to 172.16.254.y
and so on.

The reverse traffic from outside to inside should also follow the same pattern.
I do not want to put many one to one NAT statement.

Can anyone advise on this.
