Description

The model I want to run needs the Sum operation.
As the main branch links against an older version of tensorflow, that does not yet support the Sum operation, I needed to switch to the dev branch.
On the main branch it was working only with the TPU, but my model needs int16 quantization to work.
On the dev branch, I can successfully add the Sum operation, but now the Mul operation is not working anymore. When compiling while calling resolver.AddMul() I get a compiler error.
It can not find arm_elementwise_mul_s16 from CMSIS.
Would be awesome if there is a fix to that :)
