HummingBird SoC

HummingBird SoC is an evaluation FPGA SoC from Nuclei for customer to evaluate Nuclei Process Core.


To easy user to evaluate Nuclei Processor Core, the prototype SoC (called Hummingbird SoC) is provided for evaluation purpose.

This prototype SoC includes:

  • Processor Core, it can be Nuclei N class, NX class or UX class Processor Core.

  • On-Chip SRAMs for instruction and data.

  • The SoC buses.

  • The basic peripherals, such as UART, GPIO, SPI, I2C, etc.

With this prototype SoC, user can run simulations, map it into the FPGA board, and run with real embedded application examples.

Supported Boards

In Nuclei SDK, we support the following two boards based on HummingBird SoC, see:


If you want to use this HummingBird SoC in Nuclei SDK, you need to set the SOC Makefile variable to hbird.

# Choose SoC to be hbird
# the following command will build application
# using default hbird SoC based board
# defined in Build System and application Makefile
make SOC=hbird all
