its a little part of my program in VHDl...
here A is signed and 31 downto 0, where K_temp is signed and 33 down to 0;

A :=matrix_mult_1x2_2x1 ( matrix_mult_1x2_2x2 (H,P),H_prime )+R;
K_temp := "01000000000000000000000000000000" / A;

actually error arise at K_temp because A is different from constant...

i have 2 questions
first , can i know what is the value of A....any code to drawn the value of A...
second, how can i divide this as A is not constant...

Firstly, use a VHDL simulator.

Secondly, the answer depends on the capabilities of your VHDL compiler. Altera Quartus is e.g. understanding divide expressions for ieee.numeric_std unsigned and signed type. Nevertheless it may be reasonable to use a pipelined divider component from a vendor library to achieve sufficient timing performance.
