Kurzfassung englisch:
The high computational demands of the H.264 decoding process
pose serious challenges on current processor architectures.
A natural way to tackle this problem is the use of
multi-core systems. The contribution of this paper lies in
a systematic overview and performance evaluation of parallel
video decoding approaches. Our study investigates six
methods for accomplishing data-parallel splitting in strongly
resource-restricted environments inherent to mobile devices.
These methods are compared against each other in terms of
run-time complexity, core usage, inter-communication and
bus transfers. We present benchmark results using different
numbers of processor cores. Our results shall aid in finding
a splitting strategy that is best suited for the targeted
hardware-architecture.
