本文以高速级联型信号处理器IMSA100为基础,构成了一个通用的可编程的硬件结构的AR滤波器.当AR滤波器阶数为1-32阶,参数量化字长为16位时,在全精度运算的情况下,数据吞吐率为2.SMHZ,每秒可完成8千万次乘加运算.此时,输入信号的动态范围最大可达7加E,最高采样率为2.SMHZ,带通、低通滤波器最低带宽的数字频率可达万分之一,过渡带小平0.01.
Based on the high speed cascaded signal processor IMSA100, this paper forms a general programmable AR filter with hardware structure. When the AR filter order is 1-32 steps and the parameter quantization word length is 16 bits, the data throughput rate is 2 under the condition of full precision operation. SMHZ, 80 million times per second to complete the multiplication and addition operations. At this point, the dynamic range of the input signal can be up to 7 plus E and the maximum sample rate is two. SMHZ, bandpass, low pass filter The lowest bandwidth digital frequency up to ten thousandths, the transitional Xiaoping 0.01.
