PROCESSOR-SDK-DRA7X: Questions Regarding DSP Stress Testing Application in SDK

Kota Takata
Prodigy 100 points
Part Number: PROCESSOR-SDK-DRA7X
Other Parts Discussed in Thread: J6EVM5777, X5777BXGABC, DRA71

Tool/software:

I am verifying this with the PROCESSOR-SDK-DRA7X series SDK for Linux.

https://downloads.ti.com/infotainment/esd/jacinto6/processor-sdk-linux-automotive/6_00_00_03/index_FDS.html

This is a question related to the DSP firmware included in the SDK.

  • dra7-dsp1-fw.xe66
  • dra7-dsp2-fw.xe66

■ Question

Is there an application included in the SDK that can run this firmware and perform stress testing on the DSP ?

I would like to measure the power consumption when the DSP is subjected to high processing loads.

I discovered that the Yocto project includes something called "ti-dsp-benchmark."

Is this related to stress testing?

~/ti-processor-sdk-linux-automotive-dra7xx-evm-6.00.00.03/yocto-layers/sources/meta-glsdk$ grep -rn "dsp"
meta-arago-distro/conf/distro/arago-source-ipk.conf:256:SRCIPK_INSTALL_DIR_pn-ti-cgt6x = "dsp-devkit/cgt6x_${PV}"
meta-arago-distro/conf/distro/arago-source-ipk.conf:263:CREATE_SRCIPK_pn-ti-dspbios = "1"
meta-arago-distro/conf/distro/arago-source-ipk.conf:264:SRCIPK_INSTALL_DIR_pn-ti-dspbios = "dspbios_${PV}"
meta-arago-distro/conf/distro/arago-source-ipk.conf:265:SRCIPK_PACKAGE_ARCH_pn-ti-dspbios = "${MACHINE_ARCH}"
meta-arago-distro/conf/distro/arago-source-ipk.conf:275:CREATE_SRCIPK_pn-ti-dsplink = "1"
meta-arago-distro/conf/distro/arago-source-ipk.conf:276:SRCIPK_INSTALL_DIR_pn-ti-dsplink = "dsplink_${PV}"
meta-arago-distro/conf/distro/arago-source-ipk.conf:277:SRCIPK_PACKAGE_ARCH_pn-ti-dsplink = "${MACHINE_ARCH}"
meta-arago-distro/conf/distro/arago-source-ipk.conf:311:CREATE_SRCIPK_pn-ti-dsp-benchmark = "1"
meta-arago-distro/conf/distro/arago-source-ipk.conf:312:SRCIPK_INSTALL_DIR_pn-ti-dsp-benchmark = "example-applications/dsp-benchmark_${PV}"
meta-arago-distro/conf/distro/arago-source-ipk.conf:313:SRCIPK_PACKAGE_ARCH_pn-ti-dsp-benchmark = "${MACHINE_ARCH}"

I would appreciate your response.

    Hi,

    I will check internally and update you in a day.

    Thanks ,

    Hi,

    There is no pre-built or ready-to-use application for DSP stress testing included in the PSDK Linux. But, the ti-dsp-benchmark package available in the Yocto project is intended for benchmarking and can be used for stress testing purposes.

    Best Regards,

    Dear Betsy Varughese,

    Thank you for your prompt reply and kind support.

    I will try to understand the ti-dsp-benchmark specifications and proceed with my investigation.



    Could you please let me confirm two additional points.

    1) Could you please tell me the maximum power consumption value of this SoC listed in the datasheet?

    　The datasheet states that you should contact TI design team.

        We would like to know the value when CPU(MPU) and DSP(only 1 core) are under high load.


    ② Is ti-dsp-benchmark used during power consumption test ?

    　If you know, please let us know.

    Hi Kota,

    Sure. I will check internally and get back to you within the next two days.

    Hello Kota-san,

    Which exact DRA7xx part are you using?  Also, can you give more background on the request?  Is it to size the power supply/PMIC appropriately?  Or for comparison to other devices?

    Thanks,

    Kyle

    Dear Kyle ,

    I appreciate for your kind support.

    ■IC

    DR75ｘ X5777BXGABC（EVM CPU Board：J6EVM5777）

    ■Background and Purpose

    ・We are planning to adopt the DRA71

    ・We are currently evaluating its power consumption.
    　Since we could not obtain the evaluation board,
    　we are using the current evaluation board for DR75x (single-core operation)  to simulate the DR71 and conduct power measurements.

    ■What we want to know

    The design values for the power consumption of both part numbers, DR75 and DR71.
    particularly the power consumption characteristics of the SOC.

    Specifically, details on the power consumption in watts for each VDD_xxx, broken down by line.
         - the values in the red box of the diagram (VDD_MPU, VDD_DSPEVE, ... , IO VOLTAGE RAIL)

    I understand that this is an older chip and is not supported. 

    I would appreciate your response.

    Best,
    Kota

    Dear Kyle ,


    I appreciate your kind support.

    Do you have any updates on this?
    I look forward to your response.

    I understand that support is limited because this SoC is older,
    but I would appreciate your cooperation on this issue.

    Hello Kota-san,

    TI recommends one of the following three design patterns for the DRA71x EVM.  I will send you more details over email.

    Regards,
