TMS320F280049: TMU + FPU examples

Part Number: TMS320F280049
Other Parts Discussed in Thread: C2000WARE

Dear expert,

As I know, F280049 support FPU and TMU, can you please share a example of how to use TMU + FPU? I'd like to use this feature for actan, divide, and sin/cos calculation. 

Merry Chrismas in advance.

    Jack,

    What you can do is look at the following examples in C2000Ware (C:\ti\c2000\C2000Ware_2_00_00_03\libraries\math\FPUfastRTS\c28\examples). These examples illustrate the use of a Fast RTS library for FPU operations like trigonometric operations, exponent, log etc. These run faster than the traditional RTS library, but they are slower than if the TMU is used.

    In order for the TMU to be used, the Project properties for these examples will have to be modified so as to enable the TMU (under C2000 Compiler ->Processor Options), and also changing the --fp_mode to Relaxed (under C2000 Compiler -> Optimization). So you can compare performance between the FPUFastRTS library and the TMU.

    Thanks,

    Sira
