TMS320F28027: Question about floating point operation.

Hi,

The only other way is to use the floating point intrinsic based on c without hardware acceleration, which will be much slower than IQMath.

Hi Shantanu:

Thank you for your reply. I want to make a final confirmation. Which of the following three methods runs fastest?

uint16 a,b

float c

1, a=IQtoF(IQ(b*c));

2, a=b* IQ(c) >> GLOBAL_Q;

3, a=b*c;

Best regards,

Green

Please help to answer again.

Hi Shanty:
