TMS320F28379D: Proposal for CLA compiler extension

Ralf Bartling

Part Number: TMS320F28379D

Hello,

the CLA has many useful mnemonics which uses the #16FHi format like MCMPF32 MRa, #16FHi, MMAXF32 MRa, #16FHi and so on. In many cases the reduced resolution of the floating constant is sufficient for calculation, but the code by using mnemonics with the #16FHi format will be much faster.

Is it possible to define a constant format for floating point values with the lower 16 bits of the 32 bit number are zero?

Thank you very much

What version of the compiler do you use?

Please supply an example of how ...

... might appear in the assembly code. Just make up some new assembler operators, or whatever is needed. Talk about how that is different from what the assembler supports now.

Thanks and regards,

Dear George,

I use the version TIv18.12.4.LTS.

Attached you will find and example regarding my issue. The code runs on the launch pad, I can send you the code if you want.

Best regards

Ralf

Thank you for the additional information. I filed EXT_EP-10257 to request that this feature be added to the C28x compiler. You are welcome to follow it at that link.

Thanks and regards,
