    Hi TI-friends,

    I found the doc

    http://www.ti.com/lit/ug/spru187u/spru187u.pdf

    http://www.ti.com/lit/ug/spru198k/spru198k.pdf

    I'm using DM8168 with DVRRDK_02.80.00.10 and having several question about tring the optimization 

    1. I try to add compilier option but I have no idea where I can do that

    2. Could the Intrinsic functions for C64x be applied to C67x directly?

    Hi TI-friends

    I found the document like SPRU198/SPRU187

    I'm using DM8168 with DVRRDK_02.80.00.10 and having several question after trying that

    1. I try to add compilier options such as "-mt", "-op2" but I have no idea where I can do that

    2. Could the Intrinsic function for C64x be applied to C67x?

    Thanks

    => please refer to "CFLAGS_INTERNAL" inside DVRRDK_02.80.00.10/dvr_rdk/makerules/rules_c674.mk

    2. Could the Intrinsic function for C64x be applied to C67x?

    ==> basically it should be...

    Hi, 910JQK

    I use DVRRDK_02.80.00.10 on dm8168 evm board, but i do not kown how to start dsp develop then ?

    Is there any alg demos  sorece code in this kit?

    I only find the params configure interface of scd , and where is scd alg source code ?

    Could you give me some suggestions how to start dsp developping on dm8168?

    How does the dsp algs is load?

    Thank you

    Xavier,

    I think you need to repost in another issue for your requirement.

    But I can remind you something for your question

    I use DVRRDK_02.80.00.10 on dm8168 evm board, but i do not kown how to start dsp develop then ?

    ==>  1. make sure that you understand the architecture of SW in the RDK (ex: they put the M3VIDEO/M3VPSS/DSP-related source in the same folder(src_bios) )

            2. study TI DSP demo code(find the entry point inside main_c6xdsp.c )

    Is there any alg demos  sorece code in this kit?

    ==>  most of them are under DVRRDK_02.80.00.10/dvr_rdk/mcfw/src_bios6/

    I only find the params configure interface of scd , and where is scd alg source code ?

    ==> SCD alg is package into a library, you may need to ask TI guys.  But you can develop your algorithm for SCD

    Could you give me some suggestions how to start dsp developping on dm8168?

    ==> See 1st reply for your need

    How does the dsp algs is load?

    ==> algs was created insdie the DSP code. You can find that Syskink_Create() in host side, by the fundtion DSP was requested to create algs.

    That's all.
