TMS320DM64X vs. ADSP-BF5XX?

Started by Eric Meurville March 12, 2004
We have to build a DSP platform for an automotive video application. The 
DSP will be the heart of a camera installed in the vehicle cockpit (a 
truck or a car) and the system will assist the driver: lane crossing and 
obstacle detection, road signs recognition...

As DSP we plan to use either TI TMS320DM64X or ADI ADSP-BF5XX but the 
choice is difficult. Any advise or experience would be appreciated. The 
criteria are processing power, memory management including cache, 
integrated peripherals, power consumption, roadmap, software tools and 
optimized libraries quality and of course cost.

Thanks in advance,

Hello Eric,

We've had a BF533 from AD. 
My very short impression:
- harder to understand
- more limitation (concerning memory usage, programming, etc.)
- chip is cheaper
Ask your distributor to lend you a kit.
We've also DSK's from TI.
My impression:
- Very easy to bring to operation
- easy to understand
- Be very (!!!) concernd with "new" chips
(DM is not 64xx)

            Good luck,

                        Wolfgang

Hello Wolfgang,

Thank you for considering my concerns. Does it mean that for an 
immediate project you would choose TI's solution? What do you mean by 
"Be very concerned with "new" chips"?

Thanks again and Best Regards,

Eric.

Hello Eric,

My knowledge regarding the EZ-Kit of a BF533 is limited to the order I did for a colleague. 
He "investigated" the board for a short time and the price/value ratio was not convicing for our application.
(It had some restrictions e.g. programm and data is separated in RAM.)
I've a DSK6416 and it's a nice kit. For a very small amount of money you receive the board, the complete CCS
and you can explore nearly everything. They have simple examples and a good support (EPIC).
AD has some specialists but with the BF533 they were not a great help (may it was too brand new).
Look at this newsgroup and you'll see the relation between TI and AD questions ...
With the options for daughter boards there are also possibilities to enhance the DSK board.
Maybe this might help you for your rapid project.
So it's clear: For a new project I would choose TI's solution.
If you start a new project I would not rely on brand new datasheets of TMX DSP's.
TI brings chips very fast to market, so you can order samples of TMX when still is not clear
if all features are operating correct. 
If you want to be shure that document description matches reality you should wait until a DSP is a TMS.

                    Good luck,

                                                Wolfgang
