Development of a configurable soft microcontroller based on ISA RISC-V

Abstract

RISC-V is an open source architecture for the development of RISC type processors. In this work, based on the RISC-V 32I architecture, a configurable soft microcontroller is developed under the AMD-Xilinx Vivado development platform. The system allows the development of peripheral device blocks that can be added to the RISC-V processor using Vivado's IP Integrator tool, enabling rapid customization of the microcontroller. The way to integrate the peripherals to the processor is through the AXI-Lite interface, which in our proposal allows saving AXI slaves, especially in the integration of timers and PWMs.
