This is the version 1.2.1 release.

  • NMSIS-Core

    • Fix and update many CSR type define structure defined in core_feature_base.h
    • Fix protection type error in PMP/sPMP __set_PMPENTRYx/__set_sPMPENTRYx API
    • Add SMPU support in core_feature_spmp.h
    • Fix wrong CLIC macros defined in core_feature_eclic.h
    • Update RISC-V DSP intrinsic API and its comments

  • NMSIS-DSP

    • Sync with CMSIS-DSP library(CMSIS-DSP v1.15.0, commit id:8f8bb8d5)
    • Add a few Nuclei DSP N2 intrinsic APIs in core_feature_dsp.h, they are: __RV_DPACK32, __RV_DSUNPKD810, __RV_DSUNPKD820,
      __RV_DSUNPKD830, __RV_DSUNPKD831, __RV_DSUNPKD832, __RV_DZUNPKD810, __RV_DZUNPKD820, __RV_DZUNPKD830,

      change DKMMACU to DKMMAC.u, change DKMMSBU to DKMMSB.u, change DSMAQASU to DSMAQA.SU, change DDSMAQASU to DDSMAQA.SU
    • Optimize the rvv implementation of some MatMult and Complex MatMult functions
    • Fixed some doc erros in core_feature_dsp.h
    • Fixed riscv_lms_q31.c rvv bug

  • NMSIS-NN

    • Sync with CMSIS-NN library(CMSIS-NN v5.0.0, commit id:bfc54edb)

    • Optimize the rvv implementation of fullyconnect s8 function
    • Fixed riscv_nn_softmax_common_s8.c rvv bug

  • CI

    • Nuclei SDK use 0.6.0 release version, SOC still use evalsoc.
