Abstract ：
A 4-tap coefficient, 8-neighborhood subpixel search algorithm is presented in this paper to simplify hardware implementation. This algorithm is intended to be used for the fraction motion estimation module of the AV1 video coding standard. A 32 × 32 block is used as the fundamental unit for searching and interpolation in hardware implementation. Blocks of the same MV are combined in a merge grouping method to perform subpixel searches, improving search efficiency. The search method for the eight subpixel points of the current MV in a clockwise order is used to realize continuous reading data without stopping the flow, improving the work efficiency of the pipeline. Finally, a shift-and-add method is employed to implement the multiplication calculation of fixed coefficients, fully utilizing the common factor between the coefficients to reuse part of the circuit and other approaches to effectively reduce the expenditure of hardware. The interpolation and searching process of subpixels is implemented in Verilog HDL, and synthesis is performed using Design Compiler under 55 nm process conditions at SMIC with an operating frequency of up to 200 MHz, an area of 5894809.13 µm2, and a power consumption of 352.21 mW. © 2025 SPIE.

Abstract ：
Thanks to its flexible coding structure, high-efficiency video coding (HEVC) can save more coding bit rates than the previous standard, H.264. However, it also increases the complexity of integer-pixel motion estimation (IME). To speed up the encoding process, we propose a parallel spiral search (PSS) algorithm, which features the following characteristics and advantages. First, the proposed algorithm is hardware-friendly. PSS has both a fix search order that cuts the correlation between search points and a high data reuse level that facilitates the pipeline application in hardware implementation. Second, the PSS algorithm processes all prediction units (PU) blocks in parallel, which speeds up the RD calculation. Finally, the early termination strategy is proposed to end the search for unnecessary search points and further reduce search time. Experimental results show that the proposed algorithm outperforms other popular hardware-oriented IME algorithms in terms of coding speed, with the same loss of RD performance. Compared with the default full search algorithm (FSA) in the HEVC test model HM-16.7, the proposed algorithm achieves average time saving ratio of up to 92.55%, with BD-PSNR loss of 0.056 dB and an increase by 1.38% in terms of BD-BR.

Abstract ：
For the problem of serious spurious signal interference in the current MultistAge noise SHaping (MASH) structure, this study proposes an improved structure that absorbs and synthesizes the advantages of Prime-Modulus MASH (PM-MASH) and Song and Park’s MASH (SP-MASH) structures. For all initial states and constant digital inputs, the structure produces the maximum sequence length. The proposed structure (we call it SH-MASH) cascades several first-order 1-bit error feedback modulators, such as the SP-MASH structure, but it has prime-modulus quantization interval. SH-MASH structure is simulated on MATLAB. Simulation results show that the proposed architecture has a better noise-shaping capability than the PM-MASH and SP-MASH structures at the same modulator word length. SH-MASH structure is comparable to the Hosseini and Kennedy’s MASH (HK-MASH) structure, which is recognized as the best structure in the current industry; however, SH-MASH structure has a simpler structure. © 2019, ICIC International.
