基于AMBA总线的ahb_sram_slave设计资源
基于AMBA总线的sram slave设计,32位总线,支持8/16/32位数据读写,SRAM空间大小是64KB,单周期读写(本设计不支持wait,即hready都拉高)
SRAM是一个单端口(FiFo是双端口,这里就是一边读写就行,就使用单端口),大小是8*8K,支持低功耗(工作状态的功耗是low power standby 状态的几百倍),支持BIST
也预留了DFT port端口,可以有三种Model:function,BIST,DFT

按键消抖,矩阵键盘
传统的一个按键一个端口的方法,若要实现16个按键,则需要16个端口,而现在这个矩阵键盘的设计,16个按键,仅仅需要8个端口,如果使用16个端口来做矩阵键盘的话,可以识别64个按键,端口的利用率远远比传统的设计好的多,所以如果需要的按键少的话,可以选择传统的按键设计,如果需要的按键比较多的话,可以采用这种矩阵键盘的设计。

Clutter-Filtering-
。给出了时域滤波的基本原理以及通常采用的
IIR 椭圆地物杂波滤波器的设计方法。重点研究了回归滤波器这一时域滤波算
法。从正交多项式的拟合出发,给出了回归滤波器抑制地物杂波的基本原理及
其滤波实现过程。通过对回归滤波器的计算复杂度的研究,寻找使回归滤波器
计算量最小的正交多项式。分析了回归滤波器频率响应特性,比较了回归滤波
器与IIR 椭圆地物杂波滤波器的计算复杂度。利用仿真的雷达信号,分析了回
归滤波器的地物杂波抑制性能。回归滤波器实际上是一高通滤波器,它在滤掉
低频地物杂波的同时,对落在滤波器阻带内的天气回波信号同样会造成衰减。
在天气回波信号谱宽固定的情况下,通过改变天气回波信号的平均多普勒频率,
分析了回归滤波器对它的衰减情况。在基于一组实际采集的雷达信号的基础上,
给出了回归滤波器的地物杂波抑制比随着滤波器阶数的变化情况。(Firstly, this dissertation introduces the research background and significance of
ground clutter suppression, analyzes the characteristics of the ground clutter and
weather signals in the Doppler weather radars and simulates Doppler radar echo
signals (It includes ground clutter, weather echo signals and the mixture of them).
The simulated signals are used later to study the time and frequency domain ground
clutter suppression.
Secondly, this dissertation talks about the time domain filtering, gives the basic
theory of time domain filtering and describes the design method of the usually used
fifth-order elliptic infinite impulse response (IIR) ground clutter filter. In the time
domain, the work focuses on the regression filter. From the orthogonal polynomials
fit, this dissertation gives the basic theory of the regression filter for ground clutter
suppression and the filtering process using a regression filter. Through the study of
the computational complexity of regression)
