  • Add a new static memory buffer interface. By using this interface, NNoM no longer need dynamic memory allocation from libc
  • change default NNOM_TRUNCATE setting to avoid the ROUND issue for 16bit ops. RNN layer (16bit ops) not perform correctly with round (NNOM_TUNCATE undefined) #104, for use with CMSIS-NN, please enable global macro NN_TRUNCATE to avoid the same issue in CMSIS-NN.
  • Move script/lib version to 0.4.3
  • Fix memory alignment for 64bit system.

Static buffer preview, clean nnom.c

Currently, it is still a global memory. All model istances (if multiple model is used) will share the memory pool.

- new macro `NNOM_USING_STATIC_MEMORY` in `nnom_port.h` to control memory type.
- new api `nnom_set_static_buf()` to be call before any model initialization.

The memory will be use in both layer instances and layer buffer.
