STORM SoC (System on Chip) with 32-bit Wishbone Bus System

Welcome to the STORM SoC project!

This is an FPGA/evaluation board-independent, complete system on chip implementation based on the STORM CORE processor.
Most of the SoC's components were designed by myself, but the are also some IPs used, which are available here at oppencores.
All components are connected via an 32-bit, pipelined Wishbone bus fabric.

The boot ROM features a pre-installed bootloader, which allows easy program downloading to RAM or to an attached I²C EEPROM.
It is also capable of booting program files directly from the EEPROM.
Compatible programs files can be generated by using the provided WinARM-compatible makefiles.
Included IO driver libraries allow fast and easy program setup.
A tutorial shows how to extend the hardware platform with own IP cores.
