ORCONF 2016 was held earlier this month in Bologna, Italy:
ORCONF is an open source digital design and embedded systems conference, covering areas of electronics from the transistor level up to Linux user space and beyond. Expect presentations and discussion on free and open source IP projects, implementations on FPGA and in silicon, verification, EDA tools, licensing and embedded software, to name a few.
Begun as the annual OpenRISC developers and users conference, it has become a broad open source digital design-oriented event and is supported by FOSSi – the Free and Open Source Silicon Foundation.
Elkim Roa spoke about OnChip, an Open Source silicon microcontroller, designed by his research group at UIS (Universidad Industrial de Santander):
Fully-tested 32-bit RISC-V microcontroller in 130nm
The slides are available as PDF on GitHub:
OnChipUIS has several repos on GitHub related to the project including:
