I am not using any OS with TMS320. I came across one Run Time Support for Stack Depth Profiling.The following text mentioned in document. The TMS470 compiler provides a debug option to determine the maximum stack usage of an application. If the application is compiled with the -debug:sdp option, the compiler places a call to a stack depth bookkeeping routine (C_SDPBK for 32-BIS and C$SDPBK for 16-BIS), immediately after the frame has been allocated for a function. This bookkeeping routine tracks the maximum stack usage for each function. There is a profiled version of the run-time support library that can be linked when -debug:sdp is turned on. This enables you to determine the complete stack usage of an application that contains run-time support utilities (such as I/O utilities). There is an overhead associated with the -debug:sdp option. The link register (LR) is always saved when this option is turned on, since all functions in the application call the bookkeeping routine. How to use this?Howw to see stack depth bookkeeping routine(C_SDPBK for 32-BIS and C$SDPBK for 16-BIS)? Thanks, Rachit Shah

It has completely different compilers, etc. You cannot use that function on the 54x DSP. As mentioned before you should use DSP/BIOS and then look at the Kernel Object Viewer to see your stack usage.

From: aaac111 on 7 May 2008 08:54 hi rachit, i think i misunderstood your question. The solution whcih i had sent earlier is *only* for ccs. that is ,if you are not using ccs my solution will not be of any use. there are other ways check stack usage but again those are for ccs only and make use of a few dsp/bios APIs. >I am not using any OS with TMS320... i am not sure if TMS320 works without an OS. The DSP/BIOS itself is an OS. >The TMS470 compiler provides a debug option... do you mean a particular compiler for TMS470 target? are you using ccs or not? >How to use this? you will have to compile your code with the option "-debug:sdp" as given in the text extract. depends on the compiler options of the compiler whcih you are using. >How to see stack depth bookkeeping routine(C_SDPBK for 32-BIS and C$SDPBK for 16-BIS)? the book keeping routine is called by the compiler. you will have to read the text to find out how to get the data which this routine would accumulate from the funcitons. regards, aps >On May 6, 4:26 pm, "aaac111" <aaac...(a)gmail.com> wrote: >> hi rachit, >> >> If you are using CCS then there is a simpler way which might be helpful. >> at runtime click the "Kernel/object view" under the DSP/BIOS menu.

I can assure you it does, assuming that "TMS320" means any of the family of several products from TI. I've used processors in that family more often without an OS than with. -- % Randy Yates % "Though you ride on the wheels of tomorrow, %% Fuquay-Varina, NC % you still wander the fields of your %%% 919-577-9882 % sorrow." %%%% <yates(a)ieee.org> % '21st Century Man', *Time*, ELO http://www.digitalsignallabs.com |
