生成SIN波形的一个小工具

#include<stdio.h>
#include<math.h>//要用到的sin和cos在这个头文件里int main()
{int n;int factor = 4096/2 ;float _sin,_cos ; short is,ic;double pi=acos(-1.0);for(n=0;n<=360;++n){_sin = sin(n/180.0*pi) ;_cos = cos(n/180.0*pi) ;_sin *= factor;_cos *= factor;if (_cos<=0) _cos-=0.5;else _cos += 0.5 ;if (_sin<=0) _sin-=0.5;else _sin += 0.5 ; is = ( int )_sin ; ic = ( int )_cos ;printf(" %06x\n",is - 0 ); }return 0;
}
这里的FACTOR是用来拓展幅度的。比如AD9361 是12位的，12位对应的4096，，可以表达-2047到2047 所以我们去factor是2048.
if (_sin<=0) _sin-=0.5;else _sin += 0.5 ; 这部分处理是为了实现四舍五入。
做好可以综合并使用的是sine表文件如下：
/*
module sin_lut_table(.clk( ), .addr( ) , .q( ));
*/module sin_lut_table( // 3 clock delay input clk, input [8:0]addr , output reg [11:0]q); reg [8:0] addrr;
reg [11:0] qr;
always @(posedge clk) addrr<=addr;
//always @(posedge clk) q <= $signed (qr) >>> 1 ;
always @(posedge clk) q <= qr ;always @ (posedge clk)
case (addrr)0: qr <= 12'h000 ;1: qr <= 12'h024 ;2: qr <= 12'h047 ;3: qr <= 12'h06b ;4: qr <= 12'h08f ;5: qr <= 12'h0b2 ;6: qr <= 12'h0d6 ;7: qr <= 12'h0fa ;8: qr <= 12'h11d ;9: qr <= 12'h140 ;10: qr

在仿真层面得到波形如下
实际发送出去再接收回来看到的效果如下：
