questions for acronyms in data sheet SPRUGZ8E on TMS320DM814x

Other Parts Discussed in Thread: TMS320DM8148

preface: i am posting this questions here on special request from the ASKTEXAS support staff after first asking them those product related question directly.

I have the publically available data sheet SPRUGZ8E on TMS320DM814x to my hands and now I have stumbled across a few shortcuts for some hardware units for which I currently cannot find a sufficient set of informations.

 

The units and shortcuts in question are:

 

* SW3PG

 

* ISS

* ISP

* FACEDETECT

 

* DSS

* HDD_SS

 

As of now I can only find power and clock domain controls for that units.

 

For some keywords there is an entry at "3.2.17 DEV_FEATURE Register (offset = 604h) [reset = 0h]"

Further there is a document of name "efuse xls " referenced in "Table 3-20. DEV_FEATURE Register Field Descriptions"

that I have not seen so far and further don’t know how to obtain that document.

 

[...]

 

Where can I find data sheet and description of this units for checking their features and probably programming them?

Where can I find that mentioned xls document?

    SPRUGZ8E is DM814x TRM, not datasheet. See the DM8148 official site:

    http://www.ti.com/product/tms320dm8148


    We have 3 public documents:

    1. DM814x datasheet (SPRS647E) : http://www.ti.com/lit/ds/symlink/tms320dm8148.pdf

    2. DM814x TRM (SPRUGZ8E) : http://www.ti.com/lit/ug/sprugz8e/sprugz8e.pdf

    3. DM814x Silicon Errata (SPRZ343C) : http://www.ti.com/lit/er/sprz343c/sprz343c.pdf

    * SW3PG

    I think this is the three port switch (3PSW) Ethernet subsystem, documented in chapter 9 of the TRM.

    Alexander Stohr said:
    * ISS

    This stands for Imaging SubSystem, this is documented in separate addendum which is available only under NDA and through local FAE / TI representative.

    Alexander Stohr said:
    * ISP

    This stands for Image Signal Processor. This is submodule of the ISS, hence documented in the ISS addendum.

    Alexander Stohr said:
    * FACEDETECT

    I am not sure if facedetect hardware module is available in the DM814x device. I will further check and come back to you.

    Alexander Stohr said:

    * DSS

    * HDD_SS

    I think these two are the same, the Display Subsystem, which is part of the HDVPSS. HDVPSS document is   separate addendum which is available only under NDA and through local FAE / TI representative.

    Further there is a document of name "efuse xls "

    This is TI internal document, which I do not think will be helpful to you. If you have any specific questions regarding the DM814x efuses let me know.

    (sprugz8e pops up in section user guides. the term data sheet might be understood as a top level term for nearly any sort technical description - for the TI web page the section headline "Datasheet" covers what you told me. - stop with side track.)

    all terms i asked for are mentioned in that document as some attribute of the device described by it.
