12. What we thought
• Interesting image processing and
connected world
• Let’s assume if we can do below things
– Using improved hardware
– Improving (for example)
• Response time to 30%
• Power saving to 15%
• Accurate rate to 10%
Isn’t it
a big deal?

13. Is it a chance for us?
• Many changes are
hidden from
ordinary people,
usually
• Next generation infra
• Eco system

29. OpenCL(1)
• Low level hardware abstraction
• Supporting two parallelism methods
– Data parallelization
– Task parallelization
• User is in charge of optimization
– Engineer needs to know big picture
– Regression testing…

32. OpenCV
• Image processing library
• OpenCV is being worked on
supporting discrete GPU(nVidia, AMD)
with x86 only, currently
• OpenCV doesn’t support ARM OpenCL
(Planed to release in near future)

40. First Trial(1)
• From ETRI
– Hardware : Exynos 4412 based development
board. Mali-400 GPU
(http://www.hardkernel.com/renewal_2011/products/prdt_info.php?g_c
ode=G133888637376)
– Kernel : high performance
resource management
