Hummingbirdv2 E203 Core and SoC

Deploy Documentation

About

This repository hosts the project for open-source Hummingbirdv2 E203 RISC-V processor Core and SoC, it's developped and opensourced by Nuclei System Technology, the leading RISC-V IP and Solution company based on China Mainland.

This's an upgraded version of the project Hummingbird E203 maintained in SI-RISCV/e200_opensource, so we call it Hummingbirdv2 E203, and its architecture is shown in the figure below. hbirdv2

In this new version, we have following updates.

  • Add NICE(Nuclei Instruction Co-unit Extension) for E203 core, so user could create customized HW co-units with E203 core easily.
  • Integrate the APB interface peripherals(GPIO, I2C, UART, SPI, PWM) from PULP Platform into Hummingbirdv2 SoC, these peripherals are implemented in Verilog language, so it's easy for user to understand.
  • Add new development boards(Nuclei ddr200t and mcu200t) support for Hummingbirdv2 SoC.

Welcome to visit https://github.com/riscv-mcu/hbird-sdk/ to use software development kit for the Hummingbird E203.

Welcome to visit https://www.rvmcu.com/community.html to participate in the discussion of the Hummingbird E203.

Welcome to visit http://www.rvmcu.com/ for more comprehensive information of availiable RISC-V MCU chips and embedded development.

Detailed Introduction and Quick Start-up

We have provided very detailed introduction and quick start-up documents to help you ramping it up.

Release History

Notice

  • Many people asked if this core and SoC can be commercially used, the answer as below:
    • According to the Apache 2.0 license, this open-sourced core can be used in commercial way.
    • But the feature is not full.
    • The main purpose of this open-sourced core is to be used by students/university/research/ and entry-level-beginners, hence, the commercial quality (bug-free) and service of this core is not not not warranted!!!
