___________________________________________________

x"08" x"09" ..... what is this in the next code and where i can found them

i search about them and not found them in code ???? i can't understand this

___________________________________________________

if VALID_KEY_I = '1' and i_BYTE_CNTR4 = 3 then

SRAM_WREN0 <= '1';

elsif v_CALCULATION_CNTR = x"08" then

SRAM_WREN0 <= '1';

elsif v_CALCULATION_CNTR = x"09" then

SRAM_WREN0 <= '1';

elsif v_CALCULATION_CNTR = x"0A" then

SRAM_WREN0 <= '1';

elsif v_CALCULATION_CNTR = x"0B" then

SRAM_WREN0 <= '1';

elsif KEY_SIZE = 1 then

if v_CALCULATION_CNTR = x"0C" then

SRAM_WREN0 <= '1';

elsif v_CALCULATION_CNTR = x"0D" then

SRAM_WREN0 <= '1';

else

SRAM_WREN0 <= '0';

end if;

SRAM_WREN0 what's the mean of this?
