Max file that can be written by streams - steh...@hotmail.com - Feb 9 9:48:27 2007



Hi,
I am trying to run my project using streams in the simulator. My problem is that if the file
size is exceeding 80k, the streams stop writing the file. If I provide less data (<80k) it
writes everything. I cannot blame the code as it is like this

do_melp_ana()
Write_melp_output()
do_melp_syn()
write_melp_syn_output().

So atleast something should be written may it be garbage or something, but it does not write
anything. Can anyone confirm if this is a limitation of Streams? If yes is there a way to
increase the output file size?

Thanks and Regards,
Saba

Just yesterday, I used VisualDSP++ 4.5 to simulate a 21161-based 
program, with an input stream containing 240'000 16bit signed integers 
as input (file size: 1.4 MB). The output was, after about 1 1/2 hours 
of simulation, of the same size. The input and output streams were 
connected to the serial ports.

Andor
