With the rapid development of 5G network and Internet of Things, Clustered Look-Ahead (CLA) technique becomes a promising approach to further accelerate recursive digital filters for real-time applications, such as smart robots and automatic driving. However, it is not easy to quickly obtain a stable CLA pipelined VLSI (Very Large Scale Integration) architecture using the existing methods. This paper proposes a CLA Formula to accelerate the VLSI architecture design procedure through rigorous and complete mathematical derivation. Comparing the proposed method with the symbolic approach, experiments reveal that more than half of the software coding time can be saved for the designers, and the execution time of the programs can also be reduced by 168 to 30243 times with the number of pipelined stages ranging from 6 to 96.

随着5G网络和物联网的飞速发展，群集前瞻（CLA）技术已成为一种有前途的方法，可以进一步加速用于实时应用（例如智能机器人和自动驾驶）的递归数字滤波器。但是，使用现有方法快速获得稳定的CLA流水线式VLSI（超大规模集成）架构并不容易。本文提出了一个CLA公式，通过严格而完整的数学推导来加速VLSI架构设计过程。将所提出的方法与符号方法进行比较，实验表明，为设计人员节省了一半以上的软件编码时间，并且随着流水线级数的增加，程序的执行时间也可以减少168至30243倍。从6到96。
