C6A816x-tmdxevm8168 + FPGA co-processing options

hari16511

Other Parts Discussed in Thread: OMAPL138, TVP5158

Hi all,

Iam trying to identify processor + evaluation platform for 3d vision processing application. Have to decide on a development setup which is flexible enough to allow

- dual camera support (synchronous real time capture)

- Availability/Interface option to FPGA development boards.

-power enough to address the stereo processing needs.

Have the following queries to be addressed.

1) Understand 3d vision processing very similar to machine vision and hence C6A816x(http://focus.ti.com/docs/prod/folders/print/tms320c6a8168.html?qgpn=tms320c6a8168) processor is suggested. Are there any other suggestions wrt to processor selection?

2) Now tmdxevm8168-(http://focus.ti.com/docs/toolsw/folders/print/tmdxevm8168.html)being the evaluation board for the processor of interest, would like to know suggested FPGA development boards to satisfy co-processing requirements (off-loading complex computations-if required)

I see that OMAPL138 +Spartan 6 Co-processing development kits available in market. But was not able to find C6A816x + FPGA co-processing solutions in market. Are there any suggested FPGA development boards with the EVM?

3) Interface options to dual cameras, for simultaneous real time video processing and suggested camera boards for the EVM.

4) In the case of DM8168, does TI provide low level access to the HD Video Coprocessor (HDVICP 2.0) co processor for customization or only the access at decoder level is provided?

Thanks and Regards,

Hello,

The C6A816x devices could be a good match for this application, with two digital video inputs, several options for connecting to an external FPGA, and lots of DSP processing power. If you need to do video encode/decode, then the DM816x devices are a better match. The HDVICP2 access is fairly high level, with some HDVICP2 codec parameters that can be tweaked.

We do not have any FPGA or camera development boards at this time.

Marc

Hi Marc,

I was able to find EVM TVP5158EVM for multi camera interface which says it can perform "Digital Video/Audio Outputs to DaVinci HD EVM". Could you clarify whether this board is scalable to tmdxevm8168 EVM for dual camera processing ie whether support is available interms of hardware(interface options) and software(drivers).

Between can you also provide details on the FPGA development boards(say for ex. xilinx) to which tmdxevm8168 EVM interfaces are supported. (FPGA intended for performing video co-processing).

We want to prepare a prototype development setup which offers maximum flexibility.

Kindly advice,

Hari

Hello,

For questions on the TVP5158 EVM, you can try the Video Converters E2E Forum.

Sorry, but I am not familiar with any FPGA development boards. Maybe someone else can comment on that.

Regards,
Marc

Hi Marc,

With the DM816x/C6A816x/AM389x Evaluation Module EVM with daughter card ( http://focus.ti.com/graphics/tool/dm8168evm.jpg) Iam seeing serveral video ports.

Can you verify whether either analog(x2) or digital(x2) camera interface support is available in the EVM+ daughter card setup for our stereo processing?

Is there a probable date for the dual camera support to be added or it is totally out of question??

Thanks and Regards,

Hari

Marc,

I'm coming from software radio application, but also going to build with C6A8168 + FPGA (Virtex 6) co-processing.

Instead of using the EVM, we are planning to design our PCB, putting C6A8168 and FPGA together.

Spectrum Digital EVM would be a good reference.

What are the options to connect it?

Regards,

Alex

Alex,

Depending on what bandwidth you need and in what direction the majority of the data flows there are various options to connect to an FPGA. You could use McASP, McBSP, I2C, SPI, GPMC, the video in/out ports etc. It depends on the nature of the data being sent.

Marc

Marc,

I have not still procured the DM816x/C6A816x/AM389x Evaluation Module EVM or I am an FPGA expert. So kindly assist in the following.

1) My application will be for Video/imaging/vision processing and hence will require low latency, high bandwidth inteface. So in that case, what will be the suitable FPGA+DSP interface (C6A926x). (I believe GPMC, EMIF are good for the scenario. Pls clarify)

2) As I am restricted to C6A926x EVM (cannot make custom design), what FPGA interface option does the EVM expose (in the form of FMC or expansion slots?.

3) Also if I am unable to have two analog/digital camera interface support on the C6A926x EVM (which I am still not clear with), then I have to transfer the dual camera inputs through FPGA. What interface option is suggested for this?

What will be your FPGA+ C6A926x EVM inteface suggestion for making this setup work?

Pls note that I am restricted with the existing interface options provided by C6A926x EVM.

Expecting your reply

Thanks and Regards,

Hari

I'm sorry, but I'm not sure what EVM you are referring to - I am not familiar with a C6A926x EVM.

Hi Marc,

I was referring to the following EVM in the link http://www.ti.com/tool/tmdxevm8168.

Thanks and Regards,

Hari,

There are many factors which play into how best to connect an FPGA for your specific scenario.

Check this thread for some additional comments.

http://e2e.ti.com/support/dsp/integra_dsparm/f/625/p/131886/474290.aspx#474290

The EVM has connectors for all the interfaces mentioned in the above referenced thread.

The data is baseband signal between DSP core and FPGA.

It would be bidirectional as the transmitted data is going to FPGA and received data is returning back to DSP core.

After reading your linked post, it looks like GPMC and PCIe are more suitable options.

How is the speed and programming complexity between GPMC and PCIe?

Alex,

Unfortunately I can't comment on the software requirements since I am not a software guy.

I suggest you now start a new thread asking about GPMC programming and PCIe programming as you will get quicker, better responses from the software teams which monitor the forums.

Steve
