Question about TMDXEVM6657L

Other Parts Discussed in Thread: TMS320C6657

Can anyone please confirm that your TMDXEVM6657 DSP EVM is indeed a floating point processor - not a fixed point ?

How can I use floating point feature of TMDXEVM6657?

Also - can the EVM run at the 1250MHz speed, or is it fixed at 1000MHz?

Thanks much,

Asmit

    Yes it's a floating point processor (it supports both floating point and fixed point instructions.)  You can get details about the core from the TMS320C6657 product page.  There's a C66x CorePac UG and C66x CPU and Instruction Set RG available there along with much more documentation.

    To use floating point you just need to have code w/ floating point variables.  Just like programming any other C code.  When your project is setup to build for the C66x CorePac it will automatically using the floating point operations.

    The EVM only supports 1GHz operation.

    Best Regards,
