You might review the Server_getNumMemSegs()/Server_getMemStat() API calls (available at runtime after Engine_open()). These provide statistics about the memory resources on remote processors.
Calling these services after each codec create/delete may help you better understand memory usage on the DSP. Finally, note that you could also run out of other resources - e.g. DMA, HW accelerators, etc. So it's not just "out of memory" that can cause a codec create to fail.

I will modify my code now.

As you've seen, cutting the stack size down allows you to create more. You might be able to find a formula, but the real answer is "as many as you have memory for". - Rob ________________________________ From: davinci-linux-open-source-boun...@linux.davincidsp.com [mailto:davinci-linux-open-source-boun...@linux.davincidsp.com] On Behalf Of chensu.main Sent: Monday, April 27, 2009 8:03 AM To: davinci-linux-open-source Subject: Problem about DSP server config of DM6446 Hi all , In my application , I have to create one algorithm many times . Fistly I config DSP server's CFG file and set stack size to 16384 in Server.algs {} , but app can only create 7 instances of my algorithm . Then I fix stack to 4096 and I can create more . My question is How many algorithm objects can I create . Which document describe it indetail ? 2009-04-27 ________________________________ chensu.main
