Video compression is crucial in providing high-quality video services under limited network and storage capacities, traditionally achieved through hybrid codecs. However, as these frameworks reach a performance bottleneck with compression gains becoming harder to achieve with conventional methods, Deep Neural Networks (DNNs) offer a promising alternative. By leveraging DNNs’ nonlinear representation capacity, these networks can enhance compression efficiency and visual quality. Neural Video Coding (NVC) has recently received significant attention, with Neural Image Coding models surpassing traditional codecs in compression ratios. Therefore, this survey explores the state-of-the-art in NVC, examining recent works, frameworks, and the potential of this innovative approach to revolutionize video compression. We identify that NVC models have come a long way since the first proposals and currently are on par in compression efficiency with the latest hybrid codec, VVC.

As homomorphic multiplication progresses with encrypted data, noise accumulates, requiring a process called bootstrapping to restore the noise level of the new ciphertext <inline-formula> <tex-math>$ct^{prime }$ </tex-math></inline-formula>. Bootstrapping involves linear transformation processes, such as Coefficient to Slots and Slots to Coefficient, where most operations used are rotation. Rotation shifts elements in slots to new positions based on rotation index k. However, the computational cost and memory bandwidth required for a rotation adds significant overhead and limits the ability to perform FHE operations. Therefore, an efficient implementation of rotation is crucial for high-performance FHE applications. To address this problem, we optimized the datapath of rotation in the CKKS scheme to be hardware-friendly and proposed a homomorphic evaluation cluster hardware accelerator tailored for FHE workloads. Our architecture is aware of the computational and memory constraints of field programmable gate arrays (FPGAs) and performs number theoretic transform (NTT), its inverse (INTT), key multiplication, base conversion, and automorphism in a single cluster.

To achieve this, we implemented three key strategies: a dynamic control unit, a tile allocation engine, and a neural compute pipeline, which together enhance data reuse and improve the flexibility of the NLU.

Incorporating both information theory and circuit perspectives, a new general energy consumption model is proposed to capture the energy consumption of channel decoder circuits. For the binary erasure channel, lower bounds of energy consumption are derived for two-dimensional (2D) and three-dimensional (3D) decoder circuits under specified error probabilities, along with scaling rules for energy consumption in each case. Based on the proposed model, the lower bounds of energy consumption for staged serial and parallel implementations are derived, and a specific threshold value is identified to determine the parallel or serial decoding in decoder circuits. Staged serial implementations in 3D decoder circuits achieve a higher energy efficiency than fully parallel implementations when the processed data exceed 48 bits. Simulation results further demonstrate that the energy efficiency of 3D decoders improves with increasing data volume. When the number of input bits is 648, 1296 and 1944, the energy consumption of 3D decoders is reduced by 11.58%, 13.07%, and 13.86% compared to 2D decoders, respectively. The energy consumption of 3D decoders surpasses that of 2D decoders when the decoding error probability falls below a specific threshold of 0.035492. These results provide a foundational framework and benchmarks for analyzing and optimizing the energy consumption of 2D and 3D channel decoder circuits, enabling more efficient VLSI circuit designs.","PeriodicalId":93442,"journal":{"name":"IEEE open journal of circuits and systems","volume":"6 ","pages":"74-84"},"PeriodicalIF":2.4,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10870295","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143553307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
