•

HDR video pipe

–

Responsible for real-time image data processing at pixel clock rate. Processes the

raw pixel data from the ADCs in the CAB. The HDR video pipe contains a set of

correction algorithm blocks and dedicated blocks for data coding.

–

Manages the 22bit to12bit compression using a programmable 32 element PWL

table.

•

Image data transmitters

–

Video data coders and transmitters, including serial (MIPI) and parallel interfaces.

•

On chip regulators

–

Supplies the analog block and the digital core.

•

Clock and PLL

–

Provides all the clocks required for the video timing.

•

Non-volatile memory (NVM)

–

Stores production test data and part-to-part variation data for image quality

enhancement.

•

Temperature sensors

–

Allows the application to take decisions based on the sensor temperature.

3.1
