This repository hosts the project for open-source Hummingbirdv2 E203 RISC-V processor Core and SoC.
This's an upgraded version of the project Hummingbird E203 maintained in SI-RISCV/e200_opensource(https://github.com/SI-RISCV/e200_opensource), so we call it Hummingbirdv2 E203, and its architecture is shown in the figure below.
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(https://github.com/pulp-platform) into Hummingbirdv2 SoC, these peripherals are implemented in System Verilog language, so it's easy for user to understand.
- Add new development board(DDR200T) support for Hummingbirdv2 SoC.
Welcome to visit https://www.riscv-mcu.com/community-community.html to participate in the discussion of the Hummingbird E203.
Welcome to visit http://www.riscv-mcu.com/ for more comprehensive information of availiable RISC-V MCU chips and embedded development.
We have provided very detailed introduction and quick start-up documents to help you ramping it up.
The detailed introduction and the quick start documentation can be seen from https://www.riscv-mcu.com/campus-campus.html.
By following the guidences from the doc, you can very easily start to use Hummingbirdv2 E203 processor Core and SoC.
What are you waiting for? Try it out now!
In order to easy user to study RISC-V in a quick and easy way, we have made a dedicated FPGA-Board and JTAG-Debugger. Diagram as below:

-- 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!!!
-- This is release 0.1.1 of Hbirdv2.
-- NOTE:
