Releases: Nuclei-Software/NMSIS
Nuclei Microcontroller Software Interface Standard V1.0.0-beta1
Main changes in release V1.0.0-beta1.
-
NMSIS-Core
- Fix
SysTick_Reload
implementation - Update
ECLIC_Register_IRQ
implementation to allow handler == NULL - Fix
MTH
offset from 0x8 to 0xB, this will affect function ofECLIC_GetMth
andECLIC_SetMth
- Fix wrong macro check in cache function
- Add missing
SOC_INT_MAX
enum definition in Device template - In
System_<Device>.c
, ECLIC NLBits set to__ECLIC_INTCTLBITS
,
which means all the bits are for level, no bits for priority
- Fix

Nuclei Microcontroller Software Interface Standard V1.0.0-alpha.1
From release v1.0.0-alpha to now, these changes have been made to NMSIS.
API changes has been maded to system timer.
-
Start from Nuclei N core version 1.4, MSTOP register is renamed to MTIMECTL to provide more features
-
Changes made to NMSIS/Core/core_feature_timer.h
- MSTOP register name changed to MTIMECTL due to core spec changes
- SysTimer_SetMstopValue renamed to SysTimer_SetControlValue
- SysTimer_GetMstopValue renamed to SysTimer_GetControlValue
- Add SysTimer_Start and SysTimer_Stop to start or stop system timer counter
- SysTick_Reload function is introduced to reload system timer
- Macro names started with SysTimer_xxx are changed, please check in the code.
-
Removed unused lines of code in DSP and NN library source code which has unused macros which will not work for RISCV cores.
-
Fix some documentation issues, mainly typos and invalid cross references.
Nuclei Microcontroller Software Interface Standard V1.0.0-alpha
This is the V1.0.0-alpha
release of Nuclei MCU Software Interface Standard(NMSIS).
In this release, we have release three main compoments:
-
NMSIS-Core: Standardized API for the Nuclei processor core and peripherals.
-
NMSIS-DSP: DSP library collection optimized for the Nuclei Processors which has RISC-V SIMD instruction set.
-
NMSIS-NN: Efficient neural network library developed to maximize the performance and minimize the memory footprint Nuclei Processors which has RISC-V SIMD instruction set.
We also released totally new Nuclei-SDK which is an SDK implementation based on the NMSIS-Core for Nuclei N/NX evaluation cores running on HummingBird Evaluation Kit.
