Forum Post: RE: Performance of a C674x DSP core calculating Double-Precision floating point values

Hi Pubesh,

Thank you for your reply.
Sorry for my late reply.

I understand that C674x Double-Precision Floating point calculations performance as follows:

  - Floating point MACs/cycle: 2

  - Arithmetic Floating point operations/cycle: 6 (2 Multiplies and 4 Arithmetic functions, except Load/Stores and DP conversions)

In addition, here is performance for C66x.

Therefore, I understand that a C674x core is equivalent to a C66x core in Double-Precision Floating point calculations performance.

Best regards,

Daisuke
