Nuclei Microcontroller Software Interface Standard V1.1.1

This is the version V1.1.1 release.

• NMSIS-Core

  • Add CIDU support via core_feature_cidu.h, and __CIDU_PRESENT macro is required in <Device>.h to represent CIDU present or not

  • Add macros of HPM m/s/u event enable, events type, events idx

  • Fix define error of HPM_INIT macro

  • Update systimer/pmp/spmp/eclic API comment and implementation

  • Add Cache ECC related APIs

  • Due to mhartid csr update, two new API added called __get_hart_id and __get_cluster_id

    • mhartid in Nuclei RISC-V processor are now used to present cluster id and hart id
    • bit 0-7 is used for hart id in current cluster
    • bit 8-15 is used for cluster id of current cluster

• NMSIS-DSP

  • Sync with CMSIS-DSP library(branch:main, commit id:1d9e38a, after CMSIS-DSP v1.14.4)
  • Optimize some functions with RVV(such as: ComplexMathFunctions, FilteringFunctions, MatrixFunctions, StatisticsFunctions, etc.)
  • Some bugfix(riscv_mat_inverse_f32.c rvv fix, riscv_offset_q15.c p fix, riscv_fir_q15.c rvv fix etc.)

• NMSIS-NN

  • Sync with CMSIS-NN library(branch:main, commit id:61d1bb6, CMSIS-NN v4.1.0)
  • Compile independent, no longer depend on NMSIS-DSP
  • Optimize some functions with RVV(such as: ActivationFunctions, FullyConnectedFunctions, PoolingFunctions, etc.)
  • Some bugfix that make tflite-micro test successfully

• Documentation

  • Update sphinx and doxygen document version to 1.1.1
  • Use mathjax to render latex formulas instead of latex, which can avoid strange compile error
  • Change dsp/nn sphinx rst document structure to match dsp/nn doxygen documentation update

• NPK

  • Add nmsis_dsp_nn choice for nmsislibsel, it will select nmsis dsp and nn library
  • nmsis_nn library no longer select dsp library, since now it can live without dsp library
