The requirement makes no sense in principle. CPU usage does not depend on just your application, it depends on all other running processes as well. Of course, you can lower priority of your thread and/or process but if hardly makes any sense, in almost all situations. No matter, the requirements you've described are incorrect anyway. They also make no practical sense. The goal of the system performance requirements is throughput, not percentage.
