We need an suggestion for selecting processor?

Sangli,

Check C5515 Fingerprint Development Kit.

Hi Renjith ,

Thanks for the reply. Actually we already have that processor kit. We can't save more templates on it. That's why asking?. Can you suggest us a another one which fulfilled our needs.  

Sangili,

Have you checked out C6748 kit?

Renjith,

  Thanks. It's seems to close. In that, i couldn't  seen any fingerprint templates, sensor related details in application notes. Can you help me to find out the link?.  Because application plays a major role here. If you know more details about application details of this processor let me know.

Sangili,

Did you download the SDK and checked for the application?

http://www.ti.com/tool/biossw-c6748?DCMP=dsp-c6-lcdk-120524&HQS=c6748sdk

Its using Authentec AES850 swipe fingerprint sensor. Also it has 128MB NAND flash for storage. 

Renjith,

   I thankful for your support. Yes i did. That SDK doesn't have a source code for fingerprint identification it has only the bin folder. But they given everything for face detection. Since the document also not clear for maximum fingerprint storage and matching speed. 

How much storage space is required for your finger print application? I believe storage should not be a constraint as you are having external NAND flash, which has good amount of capacity. If required you can replace the same with higher capacity NAND. I'm not sure about the speed though.

we would like to store minimum 3000 fingerprint templates, each template size is 1 KB. As you point of view  the storage is not a constraint, i accept. But without knowing a knowledge of algorithm(ISO), matching speed, type of comparison(1:1, 1:N) and speed how can i able to buy a development kit. So kindly share those details if you know. Then Why they didn't provide those documents or not mentioned?. Awaiting for your answer. Thanks again.

Sangili,

I'm not an expert on finger print algorithm to comment about the performance. But I can assure one thing. It will be way better than c5515. C5515 uses a C55x DSP which is running at max 120MHz clock. Whereas c6748 has a 674x DSP which is running at 456MHz. This is much more powerful than c5515. I am not sure about the documents part. You can check with TI FAE/Sales to get more info.

Sangili,

The fingerprint algorithm in the current release of C6 BIOS SDK is provided only binary form as fingerprint sensor  IP and software was obtained from Authentec. To obtain the full source of the algorithm you will need to contact Authentec.

A word of caution with respect to the fingerprint detection feature on the C6748 LCDK. Authentec`s fingerprint sensing IP was recently acquired by Apple so all future orders of the the sensor and the software would require you to obtain proper licensing. In the light of this event, the new builds of the C6748 LCDKs are unlikely to contain the IP. You should take the above information into consideration while purchasing the kit.

Rahul

Thanks Rahul and Renjithl for the detailed support.
