complex numeric type signal in RTDX

Started by d0m1...@yahoo.com September 3, 2007
dear all,

recently i,m working on my graduate final work assignment using DSKC6713. to run my algorithm in DSK i used Model Based Design on Simulink.
I want to transfer complex numeric type signal (consist of real and imaginer part) from simulink (via write to RTDX block) to DSK and compute the signal with my algoritm which result is a signal with complex numerical type also. But, some problem occur. when I send the signal from simulink the imaginer part is missing, so the result that i have is just the real part.
when i try change the process so that the DSK produce a complex numeric type signal and send it back to simulink using to RTDX block i get an error report that explain to RTDX block can't accept signal with complex numeric type.
my question is :
1.does to RTDX block only accept signal with numeric type real?
if not, how can i send complex numeric type signal back to simulink without an error occured ?
2.what block should i add before write to RTDX block, so that the complex signal that i send to DSK doesn't lose its imaginary part ?
I really grateful if somebody can help me with this problem. thanks

best regards
