**Part Number:**TMS320F28384S

**Other Parts Discussed in Thread:**C2000WARE

Our team uses floating point calculations to support some control algorithms. We're looking for any detailed information about the 28384S and the support it gives for CPU1, CM, and CLA in regards to floating point use.

If we move from 32-bit to 64-bit floating point support on CPU1, what would be the trade-off? Speed/size? I understand that finally numbers are application dependent, but what would the tradeoff be for a single calculation? Would enabling 64-bit floating point support cause any changes to calculations that only use 32-bit floats?

Also, the CLA documentation seems to indicate that only 32-bit is supported. Can it support 64-bit floating point calculations?
