TMS320F28335: Thi is related to math.h header library

Sumit,

F28335 doesn't contain TMU. However, it contains the FPU, so it supports the FPUFastRTS libraries we provide in C2000Ware. This fast math library has a logf() operation which runs faster than the standard math library, at the cost of some accuracy.

To compute log10(x), you would do logf(x)/logf(10). logf(x) can be computed using the FPUFastRTS library. 1/logf(10) can pre-defined as a constant. So you can get the result using a logf() operation followed by a multiplication.

Thanks,

Sira
