TDA4VM: Add of 2x 64-bit (long long) impossilbe?

Part Number: TDA4VM

Tool/software:

Dear team,

I wanted to make MAC with 32bit values on C66x-core.

Found MPY32US making Multiply of Unsigned 32-bit x Signed 32-bit Into Signed 64-Bit Result (register pair).

Now I'm puzzled that I can't find any ADD for two register pairs to make the "accumulate".

 

The .M-unit seems possible to load 2x 64bit but there's no add for this unit...

Did I overlook something? Is there a workaround?

                               Thanks, Wolfgang

P.S.: Using MPYILR making multipy 32-Bit x 16-bit into 32-Bit result which then can be added to a register pair is
not a good option as I would lose bits.
