DM8168 & MCFW: DSP IPC link

Marat Shchuchinsky
Expert 2595 points


Hello guys,

what kind of IPC link I can to use to send processed data buffer (not video buffer, just raw data, aka BitsBuf) from C64 slave processor to Host (A8)?

ThanX alot for any help.

    Marat,

    IpcBitsOutLinkRTOS on Dsp and ipcBitsInHLOS on A8 can be used for sending BitsBuf from DSP to A8. This is illustrated in progressive demo for DM816x.

    Regards,

    Yogesh.

    ThanX alot for answer.

    You mean "multich_progressive_4d1_vcap_venc_vdec_vdis.c" usecase?

    But in this usecase DSP ALG link hasn't output queue and "next link" for connect and send data to next recipient. Only "input queue" and "previous link" defined.

    I mean, DSP ALG doesn't work in, let say, "traditional" link schema, where each link (outside of capture and display) has "IN" and "OUT" connectivity.

     

    Above example, if I understood correclty, used only 2 links on DSP side: SYSTEM_DSP_LINK_ID_IPC_FRAMES_IN_0 (for input) and SYSTEM_LINK_ID_ALG_0 (for processing). Other links run on VPSS, Video or Host subsystems.

    Marat,

    I meant dvr_rdk\mcfw\src_linux\mcfw_api\usecases\ti816x\multich_progressive_vcap_venc_vdec_vdis.c not the 4d1 progressive.

    Which version of RDK you are using?

    ThanX again ;-)

    My version of DVR-RDK is 01_09_00_19.

    Sorry, but in my DVR-RDK version, I don't found any difference in DSP ALG "connectivity" between 2 usecases: "multich_progressive_vcap_venc_vdec_vdis.c" and "multich_progressive_4d1_vcap_venc_vdec_vdis.c".

    I think this is my usecase, but I don't know how ipmlement this case on DSP:

    VPSS IPC OUT link

    |

    +-<------------> process link (DSP link)

    |                                                      |

    |                                                      |

    Encoder link etc.                              |

                                                    Host A8 (queue "listener")

    Marat,

    The RDK version you are using is pretty old, we would stongly suggest to move the latest one (V 2.80). This version excatly shows the IpcBitsOutLinkRTOS from DSP with output queue connected to IpcBitsInLinkHLOS on A8.

    1) May I ask you URL for download latest version?

     

    2) I think this is my usecase, but I don't know how ipmlement this case on DSP:

    VPSS IPC OUT link

    |

    +-<------------> process link (DSP link)

    |                                                      |

    |                                                      |

    Encoder link etc.                               |

                                                    Host A8 (queue "listener")

     

    3) It's a problem to use "output queue" and work by "traditional" link schema on DSP?

    ThanX again

    Marat,

    This is not possible with the RDK version you are using. Dsp lik did not have outque at that time. Which platform you are on? If you are using UDworks 816x dvr please contact them for the URL

    Ok, I'll try to upgrade my DVR-RDK version.

    Yes I'm works with UDWORKS.

     

    But on UDWORKS site latest version available for download is: 02.00.00.24. Is this version good enougth for my purpose?

    New version of RDK require update of ti_tools too?

    Marat,

    Yes 02.00.00.24 should have outque implemented so this is good enough. Regarding ti_tools, its better to update ti_tools that 02.00.00.24 supports to avoid getting into unknown issues.

    I update my old RDK version on 02.00.00.24 from UDWORKS, but this version hasn't sources of SCD algorithm. When I try compile SCD have errors as is following:

     

    make dvr_rdk_bios6_algs

    rm -rf build/lib/

    rm -rf build/obj/

    make -fMAKEFILE.MK -C /home/marat/workdir/netra_dvrrdk/dvr_rdk/../dvr_rdk/mcfw/src_bios6/alg/scd

    make: *** [dvr_rdk_bios6_algs] Error 2

     

    I saw that there are no files for SCD algorithm - only lib files and no source files. Pleas help me - where I can to get source files and fix compilation error.

    ThanX alot.
