Adaptive Loop Filter (ALF) is a new technique proposed by the latest video coding standard Versatile Video Coding (VVC). To the best of our knowledge, this paper is the first implementation to design a hardware architecture of ALF in VVC decoder. The implementation reduces 60% of the memory access, saves approximately 50% of the hardware resources including adders and multipliers cost, increases the throughput and makes the hardware configurable for luma and chroma components. The synthesis result demonstrates that the architecture achieves a throughput of 4k@120fps and a maximum frequency of 367MHz under the TSMC 65nm process.
