• NMSIS-Core

  • Add nmsis_bench.h for benchmark and hpm helper functions.
  • Add hpm related API
  • Update riscv_encoding.h for latest riscv changes.
  • Add core_feature_spmp.h for TEE/sPMP unit.
  • Add more Nuclei DSP N1/N2/N3 intrinsic APIs in core_feature_dsp.h
  • Bring SMP/AMP support in core_feature_eclic.h and core_feature_timer.h

• NMSIS-DSP

  • Sync with DSP library in CMSIS 5.9.0 release.
  • Add experimental RV32 Vector support.
  • Optimize with RVP/RVV for DSP library.

• NMSIS-NN

  • Sync with NN library in CMSIS 5.9.0 release.
  • Add experimental RV32 Vector support.
  • Optimize with RVP/RVV for NN library.

• Build System

  • DSP64 is removed, and replaced by NUCLEI_DSP_N1, which means Nuclei DSP N1 extension present.
  • NUCLEI_DSP_N2 and NUCLEI_DSP_N3 are introduced to standard for Nuclei DSP N2/N3 extension present.
  • Now you build different DSP/NN library optimized Nuclei DSP N1/N2/N3 via command such as make NUCLEI_DSP=N1 gen
  • Add nmsis_help make target to show help message to build nmsis dsp/nn library.
  • Add check_build and check_run make target for locally build or run on a small test suite configuration.
  • Add fpga related test script located in Scripts/Configs/fpga/.
  • Fix bugs found in nlbuild.py script.

• Device Tempates

  • Update Device templates to support SMP/AMP and new linker script changes to align with Nuclei SDK 0.4.0

• CI

  • Misc changes for github and gitlab ci, see commit history
  • gitlab ci will now test NUCLEI_DSP=NO/N1/N2/N3 cases and also check rv32 with VPU for DSP/NN test cases

• Documentation

  • Update Core/DSP/NN documentation

• Misc

  • Nuclei SDK 0.4.0 will use NMSIS 1.1.0
