本文提出了一种面向VLSI实现的复数域递推最小二乘算法,算法中所有的运算都映射到了一个全由CORDIC单元组成的脉动阵列并行处理结构中,该阵列可直接对数据矩阵进行线性约束的自适应滤波而避免了复杂的滤波器复权系数求解.本文还介绍了为该算法设计的超大规模专用集成电路芯片,利用该芯片可组成数据采样率为2MHz的可重构的实时自适应滤波器.
A kind of real-time processing algorithm for RLS(Recusive Least-Squares) adaptive filter is proposed which is very suitable for VLSI implementation. All the operations needed in the algorithm are mapped into a systolic array which is constituted by only CORDIC units. The least-square residue can be directily deduced from the array without solving the complex weights.And a full-custom 90
000 transistor ASIC for this array has been designed and manufactured with 1.2μm CMOS technology
with which a adaptive filter can be built with data sample rate of 2MHz.
