The Ultra-Low Power RISC-V Core

Hummingbirdv2 E203 Core and SoC

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.

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.

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!!!
