Programmable in-loop deblock filter processor for video decoders [PDF]
2014 IEEE Workshop on Signal Processing Systems (SiPS), 2014 The short time to market cycle and the target to reduce design and verification costs are driving forces to design programmable implementations of the video processing algorithms. We present two processor architectures the first one representing an application-specific instruction set processor (ASIP) design, whereas the second architecture represents ...

Virtual inertia analysis of photovoltaic energy storage systems based on reduced-order model
Frontiers in Energy Research, 2023 The problem of non-ideal inertia of the photovoltaic energy storage system (PVESS) may occur due to unreasonable voltage control parameters. In response to this issue, this paper establishes an equivalent reduced-order model (EROM) for PVESS.
