Use of only DSP without peripherals

Which DSP and EVM board are you considering using?

Which peripherals do you wish to avoid using?

Why did you choose DSP/BIOS as your only Tag to this post? What role does DSP/BIOS have in this discussion?

RandyP

Hi RandyP ,

The EVM is Texas Instruments :

C6748 http://processors.wiki.ti.com/index.php/L138/C6748_Development_Kit_(LCDK)

I will develop an application in this EVM. After the development I will juste use the processor and add my peripherals. I need some peripherals. I do this to because the EVM is expensive. 

Analog camera ==>Video encoder => DSP C6748 => Video decoder

I was wrong. The dsp/Bios hadn't any relation to the subject

Hi,

Thanks for your post.

Yes, it is possible to use only DSP stand-alone to run signal processing algorithms which are typically used in computationally intensive real time applications where optimal execution speed of the processor is critical.

To accomplish the above, you can download c6000 DSP libarary software and try invoking the libaray kernel functions available in the libaray package in your application code.  Kindly refer the c67x DSPLIB programmer's reference guide as below:

http://www.ti.com/lit/ug/spru657c/spru657c.pdf

There are signal processing examples on c67x DSP LIB, please refer the application report below:

To download c6000 DSP LIB. software, please refer the below:

To know the usage of single precision kernels available in c674x DSP LIB, please refer below;

thank you very much !!

You can do as you describe above, use the EVM for development and then design/build your own board. Since it can be difficult to design with the high-speed signals and small dimensions of the C6748, you may want to look at some of the C6748 SOM (silicon on module) products that can be added to your own board more easily than designing the high-speed portion of the board.

The EVM can be viewed as an example of how to use various peripherals. If you can do it, the best method for you would be to remove the peripherals you do not need, but use the same ones connected in the same way as they are on the EVM. This will improve you chances for quick success in your product.

Thank you very much

i think it is the best solution

Hello !!

I would know wich peripherals i should use to do video processing. I think i will use :

-- Processor : TEXAS INSTRUMENTS - TMS320C6748BZWTA3 - IC DSP FIX/FLOAT POINT 361NFBGA                 http://fr.farnell.com/texas-instruments/tms320c6748bzwta3/ic-dsp-fix-float-point-361nfbga/dp/2219171

-- Decoder : TEXAS INSTRUMENTS - TVP5147M1PFP - IC, DIGITL VIDEO DECODER 80-HTQFP
http://fr.farnell.com/texas-instruments/tvp5147m1pfp/ic-digitl-video-decoder-80-htqfp/dp/1755452

-- Encoder: ANALOG DEVICES - ADV7343BSTZ - IC, ENCODER, VIDEO + 6 DACS, LQFP64
http://fr.farnell.com/analog-devices/adv7343bstz/ic-encoder-video-6-dacs-lqfp64/dp/1439010?Ntt=ADV7343


The EVM Booard :


I would keep the component that i will need to do video process and make my own board :

Wich components i shoud keep. Do you have the reference of components ?
