Changelog

[0.4.0] - 2024-12-30

Added

  • NnxBuildFlow and CmakeBuildFlow
  • Neureka V2 support
  • github action for testing neureka
  • add NnxMapping dictionary that maps accelerator name to the accelerator specific classes
  • choice of data generation method (ones, incremented, or random)
  • N-EUREKA accelerator support: 3x3, 1x1, and 3x3 depthwise convolution kernels
  • Support for kernels without normalization and quantization for NE16
  • isort check
  • publication citation
  • support 32bit scale
  • cmake support
  • const qualifier to <acc>_dev_t function arguments
  • support for N-EUREKA's dedicated weight memory

Changed

  • wmem is no more a test configuration argument but a command line argument
  • neureka is now tested with a more recent gcc version
  • python requirements are changed into requirements-pip and requirements-conda
  • conftest now passes only strings to test.py to improve readability of pytest logs
  • NnxMemoryLayout is now NnxWeight and also has a method for source generation
  • the wmem field in the test configurations is now required
  • ne16_task_init got split into smaller parts: ne16_task_init, ne16_task_set_op_to_conv, ne16_task_set_weight_offset, ne16_task_set_bits, ne16_task_set_norm_quant
  • strides in ne16_task_set_strides, ne16_task_set_dims, and ne16_task_set_ptrs are now strides between consecutive elements in that dimension
  • ne16_task_queue_size is now NE16_TASK_QUEUE_SIZE
  • ne16_task_set_ptrs split into ne16_task_set_ptrs_conv and ne16_task_set_ptrs_norm_quant

Removed

  • k_in_stride, w_in_stride, k_out_stride, and w_out_stride from ne16_nnx_dispatch_stride2x2
  • mode attribute from ne16_quant_t structure

Fixed

  • global shift should have been of type uint8 not int32
  • type conversion compiler warning

[0.3.0] - 2024-01-14

Added

  • New Hardware Processing Engine (HWPE) device in util/hwpe.h
  • A device structure for ne16 ne16_dev_t in ne16/hal/ne16.h which extends the hwpe device
  • Test app Makefile has now an ACCELERATOR variable to specify which accelerator is used

Changed

  • Library functions no longer start with a generic nnx_ prefix but with <accelerator>_nnx_ prefix to allow for usage of multiple kinds of accelerators in the same system
  • Decoupled board specific functionality into ne16/bsp which also contains constant global structures to the implementations of the ne16_dev_t structure
  • Moved all task related functions (nnx_task_set_dims*) into ne16/hal/ne16_task.c
  • Tests adjusted for the new interface
  • Test data generation moved into source files with extern declarations to check the output from the main

Fixed

  • pyright errors
  • formatting errors

[0.2.1] - 2024-01-08

Fixed

  • Stridded 2x2 mode needed to propagate padding_bottom when input height is smaller then 5
  • Test requirements where missing the toml dependency and

[0.2.0] - 2023-10-25

Added

  • Added timeout parameter to conftest.py
  • Added stride arguments to nnx_task_set_dims, nnx_task_set_dims_stride2x2, and nnx_dispatch_task_stride2x2

[0.1.0] - 2023-09-22

Added

  • Initial release of the repository.
