您好
1,最近看到rt600有密码加速器(Cryptographic Accelerator (CASPER)),发现密码加速器中有乘法器和加法器,请问一下这些算术加速器是有符号运算还是无符号运算的,例如乘法器是有符号乘法器还是无符号乘法器
2,还要rt600的powerquad中关于IIR的运算精度需要怎么计算,如下图res和ref分别代表什么??

Hi
不太明白关于powerquad iir精度的计算,是否可以举个计算的实例,这个理论值和实际值是否和int32,int16,fp有关??
Hi ,
IIR滤波器的性能评价指标(如SNR:信噪比),说实话,我们也不是很了解,建议你自己去参考数字信号处理相关的书籍。
在SDK中也有PowerQuad关于IIR的测试代码,你也可以运行测试一下。
