# Background
|
|
|
|
TFLM is designed to run on microcontrollers and other platforms without dynamic
|
|
memory allocation and without filesystems. This means that data files such as
|
|
TFLite models and test inputs must be built into the binary.
|
|
|
|
Historically, data files have been included as cc arrays generated manually
|
|
using `xxd -i <data file> > data_file.cc`
|
|
|
|
# Data Files in Examples
|
|
|
|
In order to clean up examples, make test inputs easier to understand, and
|
|
include TFLite models directly, TFLM has moved to generating the cc and header
|
|
files during the build process using a python script which `make` and `bazel`
|
|
call. To include data files in an example, generator inputs should be supplied
|
|
to the `microlite_test` call in the example's Makefile and `generate_cc_arrays`
|
|
should be used to create cc and header sources in the BUILD file.
|
|
|
|
For reference, see the
|
|
[Makefile](https://github.com/tensorflow/tflite-micro/blob/main/tensorflow/lite/micro/examples/hello_world/Makefile.inc)
|
|
and [BUILD](https://github.com/tensorflow/tflite-micro/blob/main/tensorflow/lite/micro/examples/hello_world/BUILD)
|
|
files in the [hello_world
|
|
example](https://github.com/tensorflow/tflite-micro/tree/main/tensorflow/lite/micro/examples/hello_world).
|
|
|
|
The generated cc and header files can be found in
|
|
`gen/<target>/genfiles/<path to example>`.
