| 摘 要： | 本文提出了一种改进的二维IIR数字滤波器的脉动(SYSTOLIC)结构。与现有的结构相比较,消除了阵列外行间的加法器,具有更规则的阵列结构;采用一维线性结构形式,具有更灵活的高阶扩展的性能;同时采用数据通道不同速率控制,使整个结构兼具有流水节拍周期小和邻近数据传递的优点,并且需用的延迟器(或锁存器)数较少。

| Abstract: | An improved systolic structure for 2-D IIR digital filters is proposed. In comparison with other available structures, it has a more regular array architecture and more flexible expansibility, since it cuts down extra adders outside the array and consists of linear array of homogeneous PEs (Processing Elements) , The multirate technique is adopted to control the various data channels, therefore the whole structure possesses the advantages of shorter pipeline period, transmitting between adjacent data, and needs less number of delays as well. |
