Hi

Simple questions, but i could not find implicit answers.

1. Is the TMU on TMS320F28388D 32 or 64 bit

2. Has any of the C2000 prosessors 64-bit TMU currrently

3. And has TI currently any optimized libraries for 64-bit calculations of sin, cos etc. on C2000 family .

Thanks for your answer in advance.

    Hi Tommi,

    1. The TMU is an extension to the FPU32 accelerator, so it is 32-bit (single precision) floating point.

    2. Currently there is no 64-bit version of the TMU.

    3. There are accelerated 64-bit operations in the FastRTS library in C2000Ware.  From your C2000Ware installation directory, the library will be at: \libraries\math\FPUfastRTS

    I hope this helps.

    Regards,

    Richard
