i have implemented fir filter in direct form 1 and it's transpose in VHDL using xilinx software.Now the question is which filter that is direct form 1 or it's transpose form will perform faster and how to check the speed of the filter in xilinx sofware . Again how to improve the performance of the multiplier in these filters?
 

1) You can check the speed by running a simulation
2) If you are using dedicated multipliers, there is nothing you can do to improve their speed; the only thing you can improve is the speed of the logic external to the multipliers.
