TMS320F280049: Comparison between fixed point and float point C2000

Part Number: TMS320F280049

Hi expert,

Could you let me know if we have any documents comparing prons and cons between old fixed point device and float point device? One team here used to use our fixed point devices and would like to switch to float point ones. They have some concern here.

Thanks

Sheldon

    Sheldon,

    I'd start with the opening chapter of the FPU user's guide, which contains a summary of the differences :

    http://www.ti.com/lit/ug/sprueo2b/sprueo2b.pdf

    If the original fixed-point code development was done using the IQmath library, it will be very simple to port to a floating-point device.  Refer to section 3.11 in the IQmath user's guide if this is the case.

    Let us know if there are any specific questions or if this isn't what you were looking for.

    Regards,

    Richard
