Projects

The details of the various assignments that I have handled in SAMSUNG SEMICONDUCTOR INDIA R & D are listed here, in chronological order.

Project Development of Secure Rendering Feature in Mali Graphics Driver Exynos 7880 chip

Description Secure Rendering feature for Gear VR application

Responsibility Gear VR application demands that its contents are protected and not shared. To meet this requirement secure rendering feature was added kernel graphics driver. I added Buffer protection mechanism during fragment buffer operation. 3 memory regions of GPU i.e. GPU Colour Buffer, CRC Buffer and GPU surface was made secure using TZPC feaures.

Environment C language and Target : Linux OS
