structural vhdl code for fast walsh transform

hi all, m trying for structural vhdl coding of fast walsh transform.I m facing problem with the following circuit.I hav coded each component and then interlinked. The main problem i am facing is with the binary loadable counter though CE signal goes high the counter does not increase, even if the component does individually.The circuit and the necessary program is attached.pls help me its urgent.I want 2 know whether my procedure is correct or there should be some timing constraints.
