MDDI (Mobile Display Digital Interface) is Qualcomm's technology for high-speed serial interface between their MSM (baseband) chip and the peripheral including display module and camera module.

In 2006, I leaded the development of MDDI IP (Intellectual Property) including analog PHY and logic core.
The IP is successfully evaluated to 300Mbps for a data lane and supports dual display.
I designed my own MDDI logic core that receives 4-bit wise parallelized data and extract packets containing commands and display pixel data and transfer it to various legacy interfaces for the straightforward integration.
It requires only 30% area of Qualcomm's original MDDI core nonetheless it has the almost the same features.

Working with Qualcomm people was good experience and I still working on MDDI 1.2 with them.

In 2006, I visited Qualcomm HQ at San Diego to attend MDDI (Mobile Display Digital Interface) Training Course.
It was very nice to meet them
They are always smiling and wonderfully generous.
It was very impressive to see their working style especially that the manager was respecting his engineers.
I am still working with Brian for MDDI 1.2 supporting products.
