Part Number: TMS320C6747
Other Parts Discussed in Thread: SYSBIOS

Dear Champs,

I created pdkproject in pdk_omapl13x_1_0_0 directory and build it using CCSv7.1.0, and am analyzing its memory usage now to estimate final memory size of customer's application.

I found total memory usage of this example was 514KB(525,835 Bytes), but can not select exactly which component should be used and what is expected memory size except application code.

And also customer requested to explain each component. I got below information from map file.

Could you please let me know which components will be used in real product in normal?

Could you please your estimated memory size of customer's system except application?

Especially I want to know what is cfg(audiosample_pe674.oe674) and if this will be needed in real product.

Below table is memory size of each module.

attached map file for reference.

    Hi Sung-IL,

    I've forwarded this to the McASP software experts. Their feedback should be posted here.

    Hi,

    I found this large memory caused by heap memory setting in the BIOS cfg file, and I got 327, 835 Bytes after reduce this to 2000.

    Could you please let me know your idea how I can optimize memory size further?

    EDMA3 library is one of items requiring large memory. should all these memory size will be needed? can RM be removed in the customer's system?

    Thanks and Best Regards,

    SI,

    Please note that the the example that you are using is using TI RTOS, EDMA RM and DRV and the MCASP driver for implementation and as you mentioned has large buffers(from Heap) for ping pong buffer mechanism.

    The small footprint MCASP example that you had requested is being implemented is using Function CSL and EDMA without using EDMA RM and drv usage.

    The small footprint MCASP example for 2/8 channel is provided under the directory path pdk_omaplxx_x_x_x/packages/ti/board/diag/mcasp and pdk_omaplxx_x_x_x/packages/ti/board/diag/mcasp_audiodc


    Regards,

    Rahul

    The board diag examples can be built only using makefiles. To build the mcasp examples in diag follow the instructions provided here:
