Toolchain

New and changed features

  • Toolchain watermarking (annobin) function has been added.
  • AddressSanitizer shadow scaling option has been applied to reduce runtime overhead on RAM.
  • libasansi library has been introduced to support dotnet ASan runtime.
  • gcov-force-options package has been added. This package has scripts to enable automatic package coverage instrumentation.

Fixes

  • GCC
    • Bugfix on Internal Compiler Error (ICE) has been back-ported from upstream - bug #83623 #85496.
    • LeakSanitizer allocator bug on 64-bit target (aarch64, x86_64) has been fixed.
    • IntegerSanitizer option’s bug with “-fsanitize=shift,unsigned-integer-overflow” has been fixed.
    • AddressSanitizer runtime option has been modified (allocator_may_return_null=1) to provide better report.
  • GLIBC
    • fclose SIGABORT issue on multi-thread environment with race condition has been fixed by applying bug fix of #15142.
    • New localedata(tl_PH) has been added (bug #15260).

Machine Learning

New and changed features

  • Inference API set
    • Neural network pipeline API set has been added. This API set allows you to construct and execute data stream pipelines with neural networks, tensor operators, input nodes, and multimedia filters.
    • Neural network single API set has been added. This API set allows invoking neural network models with simple API calls.
  • NNStreamer
    • NNStreamer 1.0 has been added as a set of GStreamer plugins to enable the Inference API set.
    • NNStreamer in Tizen 5.5 M2 supports TensorFlow Lite (1.13) models, custom C/C++ models (.so files), and python codes. Such models may be supplied by applications as resource files.
  • nnfw: Neural Network Runtime
    • nn package has been introduced to support the direct loading of TensorFlow Lite models.
    • In order to use nn package independently, a new Runtime API set has been introduced. (Experimental)
    • Custom operator has been supported. For operations that are not provided by runtime as built-in, you can define and implement them and use them through nn package and the Runtime API set.
    • [Performance optimizations] In supporting complex acceleration that inferences one model by using a combination of CPU and GPU, new parallel scheduler provides 30% better performance than single acceleration.
  • TensorFlow Lite has been updated from version 1.09 to version 1.13.

Known Issues

  • Neural network single API set
    • With a given handle, the dimensions of input tensors should be identical. If the dimensions are changed, a handle should be closed and re-opened.
  • Inference API set
    • It supports TensorFlow Lite (.tflite) and custom C (.so) models. In Tizen 5.5, TensorFlow (.pb) and nnfw-runtime models are not supported.
