Hi Zihao,

Yes C29CPU supports this in hardware : This compiler intrinsic counts leading zeros : unsigned int __builtin_c29_i32_clzeros_d(unsigned int ui0)

Thanks

Example for the above intrinsic is as below :

leadingzeroes = __builtin_c29_i32_clzeros_d(0x4);

leadingzeroes variable value is expected to be 29 in the above case.

Thanks
