  • Forum Post: Re: VICP and image/video library

    Juan Gonzales
    Because VICP is very complex to program, this co-processor is used primarily via codecs available from our Authorized Service Providers (ASP) network. If you require access to this, you need to work with your local sales representative (NDA required). For a list of local sales representatives, see ...

    Bernie Thompson TI
    In general you use the VICP through codecs supplied by TI or third party codec providers, documentation is sparse because the peripheral is only really targeted at third party codec providers who work closely with TI, the VICP is not widely supported because of its complexity. There are no individual...

  • Forum Post: Re: Programmable part of VICP (DM6446)

    Juan Gonzales
    Amit, Due to its complexity, at this moment, the VICP is closed and only exercisable thru codecs available from TI and our ASPs; however, we are looking into providing a library with defined API so our customers can take advantage of the extra processing power of VICP for their own DSP algorithms.

    Bernie Thompson TI
    This is essentially the same in the case of DM648, the VICP is not publicly documented, typically you would only use the VICP through codecs available from TI and third parties. If you plan on doing codec development that may benefit from the VICP you may want to work with your local TI contact to see...
