Hi Kishor
yes i.MX7 EPD improved, in particular LUT memory increased twice.
Please create service request for obtaining more info.
Best regards

Hi Igor,
From this thread:
https://community.freescale.com/message/620845?et=watches.email.thread#620845
I got the answer that LUT memory is increased twice. Can you let me know
the impact of that?
From this link:
http://goodereader.com/blog/electronic-readers/the-future-of-e-readers-is-imx-7
See below snip.
Do you think below information is valid?
"The IMX 7 Dual will be the saving grace of e-readers, it has been totally
optimized for e-ink Regal and whatever new technologies that are released
by E INK in the future.
Why is this important? Page turn speed will be dramatically increased. In
the past this mechanism was handled by software, which prevented companies
like Amazon, Barnes and Noble and Kobo from taking a big step forward in
innovation. Now, page turns are handled by the hardware itself.
The rate in which page turn speeds occur heavily depend upon the waveform
that the e-Reader uses. The update times can range between 125 mSec – 500
mSec. By integrating the REGAL waveform support in hardware, Freescale
are taking away any additional time that would be added due to Algorithm
processing on the Cortex-A core, hence a savings of up to 150 mSec.
Solving the page turn program is a big step forward, but that’s not the
only thing that is being remedied. Ghosting will also be solved with this
framework, which is a huge deal. Normally with e-readers you will have a
full page refresh every six pages or in some cases every chapter. The
reason for this, is the longer the display goes without a full page refresh
text gradually starts super imposing itself, which makes it difficult to
read. I have never liked full page refreshes, as it breaks reading
immersion. Now, this will also be fixed, which means less full page
refreshes because again, its now hardware based, instead of software.
Likely the largest innovation in the IMX product line is the support for
hardware dithering. This will allow e-reader companies that work with the
Linux or Android platforms to be able to include animated content. This
will include truly animated page turns, interactive menus and video.
