—This letter analyzes the coding efficiency of distributed video coding (DVC) schemes that perform motion-compensated interpolation at the decoder. The decoder has access only to the key frames, when generating the side information for intermediate frames. Therefore, the true motion field necessary for this operation is not directly available, and the(More)
In this paper we propose the use of Timed Coloured Petri Nets for the Performance Evaluation of Hardware/Software systems for DSP applications. Complex systems on chip, composed by hardware and software parts, are often required to meet strict timing constraints, both in terms of throughput and latency. However, the verification of the suitability of a(More)
This article proposes a hardware/software partitioning method targeted to performance-constrained systems for datapath applications. Exploiting a platform based design, a Timed Petri Net formalism is proposed to represent the mapping of the application onto the platform, allowing to statically extract performance estimations in early phases of the design(More)
This paper analyzes the coding efficiency of distributed video coding (DVC) schemes that perform motion-compensated interpolation at the decoder. The decoder has access only to the key frames when generating the side information for intermediate frames. This fact introduces a displacement estimation error that depends on several factors: 1) the overall(More)
