futh0403 bcd12f7063 复数乘法器资源优化 
乘法器开销由4个优化至3个
 2025-05-26 18:19:26 +08:00
futh0403 c2e7492c21 Merge branch 'b2' 2025-05-26 15:29:33 +08:00
futh0403 ad84ffcd89 与b2支路合并 -TailCorr_top.v需要b系数，其它模块做出对应修改 2025-04-15 16:15:48 +08:00
thfu 728532bd61 降低位宽 
采用求最优解的方法求解位宽；
不同的系数采用不同的位宽
 2025-03-19 15:59:00 +08:00
futh0403 6e386a2743 合并main分支的部分修改 
-尽量避免使用for循环
