IPIPE DM8148 vs DM8127

Hi,

The post is right, DM8148 is a superset of DM8127.  There is an ISS chapter in new DM8148 TRM and it has  IPIPEIF and IPIPE in there.  This new TRM is target to go to TI producct folder next wee.

BR,

Hi Viet,

Thank you very much by the clarification. I will wait anxious by the new TRM. So maybe the DM8127 IPNC is using DM8148 and it is not a problem since it is a superset of DM8127. I will not worry about this anymore.

HI,

These are top level differences between DM8127 and DM814x.

For IPNC suggest using DM8127 as this has Face detect and RDK (reference design Kit) is based on this chip.

Also, for development please plan to use Reference design kit available at www.ti.com/ipcamera , please look for TMDSIPCAM8127J3

This has the IPNC usecase along with related drivers, hardware details etc shared which helps development

Let us know if you any further details

Thank you Raghu,

I already have the TMDSIPCAM8127J3 kit. It is in my hand now. I am the hardware designer and I am worried because TI is saying the DM8127 is only for "volume" markets. This specific camera product is not for security market (for the general security we are using DM365), so the volume is not so big (but not so small too). I am asking my TI local representative about what "volume" means, but he did not answer me for days.

I would like to be confident that I will have an alternative (DM8147), even if it is more expensive, if we can not buy DM8127. I will use DM8127 if possible, it will be perfect for my application.

Face detection lack in the DM8148 is not a problem. What I am worried about are the other ipipe features that are missing in the DM8148 datasheet and are in the DM8127 datasheet, mainly the IPIPE block features like:

– Raw Data processing (IPIPE Front End)
• On-the-fly or memory to memory processing
• Supports up to 5376 pixels per line in single processing
• Sensor data linearization for dynamic range extension
• Programmable 2D Lens Shading Compensation (LSC) correction
• Black level compensation
• Defect pixel correction (LUT_DPC) with look-up table
• Defect pixel correction (OTF_DPC) with on-the-fly detection and correction
• Two spatial noise filtering
• Digital gains and offset
• A-law and DPCM compression/decompression for saving memory space

– RGB and YUV DATA processing (IPIPE Back End)
• Fine color correction through color correction matrices and 3D look-up table
• Programmable Gamma Correction
• RGB -> YUV4:2:2 : color space conversion
• Edge Enhancement (EE)
• False Color Suppression (FCS)

There is the Hardware 3A Engine (H3A) that I would like to use too and is not present in the DM8148 datasheet.

I would like to be sure that this features are present in the DM8148.  By your table the DM8148 has FULL ISS. The ipipe is inside ISS, so I can conclude that I will have all this features in DM8148, agreeing with what Viet tell me, it is right?

As Viet said, DM8148 will also have ISS and all those mentioend in the mail.

The differences with DM8127 are those which i sent in pdf.

But for IPNC suggest using DM8127 as we also use the same chip in our IPNC RDK

It will be easier for us to support too.

Can you please work with TI sales for details on DM8127?can you please tell us which TI sales are working with so that we can inform them about it?

Raghu

Thank you again. That is confirming the good news.  About the DM8127, I will try to use it. We are in Brazil and TI local office here is working with us, together with Arrow representatives. My commercial/technical contact from TI here is Mrs. Letice Kubert, and technical support contact is Mr. Luiz Fernando da Silva.  I don`t know if you have contacted him, but Luiz call me few moments ago. What he tell me is that the DM8127 is only for "vertical" market, that would means, according him, I probably could not buy it since it is intended only for products with global distribution and very high volumes.

In the documents and Seminar presentations that I had access the DM8127 is showed in the roadmap as the choice for high-end cameras with analytics. This is exactly the case of this application and I don`t understand why there are restrictions. There are videos in the TI site about the DM8127IPNC kit, about the features, etc. and recommending the kit and now I can`t buy the IC. It is a little frustrating.

We are a camera manufacturer until now specialized in special cameras for traffic control, identification and other government applications. We have a strong market share here in Brazil in this area. Now we are starting in the general security market too, using TI solutions, to cover a lack of quality products in this market here in Brazil. We would like to have a stronger partnership with TI.

I really would like to revert this position and use DM8127 in many products.

I would also like to know this. I'm comparing Hi3516 with DM8127 and it appears Hi3516 has no such restrictions.

from ti.com/ipcamera where I can purchase 8127 IPNC, nowhere mentioned something like "buy devkit here, but the 8127 silicon is restricted to certain vertical markets", confusing.

Hi,

DM8127 is the IPNC chip and it will be available for this market.

Please use this and let us know if you face any issues.

We will help/support for the chip via IPNC RDK

Please check with local TI sales team and let us know if you have any issues
