Piccolo is intended for low-end applications (Embedded Systems, IoT, microcontrollers, etc.). This is one of a family of free, open-source RISC-V CPUs created by Bluespec, Inc.

The Piccolo BSV source code in this repository, from which the synthesizable Verilog RTL in this repository is generated, is highly parameterized to allow generating many possible configurations, some of which are adequate to boot a Linux kernel.
