Open implementation of the x86 architecture
OpenSOC86 is an open implementation of the x86 architecture in Verilog. The current version only implements the 16-bit part (real mode). The processor is a pipelined architecture clocked at 100 MHz in a Cyclone II speed grade -6. Therefore it can be seen as similar to a 486 in real mode. Several peripherals are also implemented in a somewhat minimalistic way, but enough to be able to boot an IBM PCXT compatible bios and MSDOS 6.22. The current implementation is only proven to boot the bios and DOS in simulation. The system is targeted to run on the DE2-70 board. In order to run the system in hardware a SDRAM and SRAM controller need to be added. These are currently in development.

Simple AVR OS
An Embedded System simple Operating System Framework that allows rapid development of applications build for AVR family but can be ported to other architectures easily enough. System is Round-Robin Co-operative multitasking. Supports: UART, SysTick Timer, ADC, SPI, EEPROM, PWM. Also supports: Xilinx FPGA configuration, FPGA SSI interface, smart card reader etc. Tested partially (different modules in each case) on ATMega163/16/32/323/8. Additionally tools for converting FPGA bitstreams to C table are provided.
An Open-Source Library for Low-Power Approximate Computing Modules
The “lpACLib” library contains the VHDL description of accurate and approximate versions of several arithmetic modules (like adders and multiplier of different bit-widths) and accelerators. Moreover, it also provides the corresponding software behavioral models/implementations developed in C and MATLAB to enable quality characterization. Besides our novel designs, it also contains implementations for several state-of-the-art arithmetic modules and their approximate versions. This open-source library facilitates research and development in approximate computing at higher abstraction levels, and to facilitate reproducible research and comparisons.

Framework for Adaptive Hardware Concurrent Systems with DPR-FPGAs
This project introduces new FPGA architectural tools and Linux OS modifications that aid in supporting Dynamic Partial Reconfiguration (DPR) on FPGAs for concurrent control. It shows that control systems benefit from hardware concurrency, meaning that by moving the control intelligence into hardware, the negative effects inherent to threads and their scheduler are minimized. This leaves software with the role of a high-level administrator rather than an executor, thereby eliminating unnecessary bottlenecks. The tools described in this project enable the hardware engineer to develop DPR-FPGA systems more effectively for rapid control system development.

X-RT: A portable multiprocessor real-time scheduling framework
This project contains the material discussed in my PhD dissertation, entitled "Hardware/Software Design of Dynamic Real-Time Schedulers for Embedded Multiprocessor Systems." The source code is available in the SVN repository: https://sourceforge.net/p/xrt/code/6/tree/trunk/ and consists in two folders: 1) /X-RT : A portable multiprocessor scheduling framework supporting scheduling periodic real-time tasks according to the G-EDF (Global Earliest Deadline First) scheduling platform. Current version supports major POSIX systems (Linux, QNX). 2) Hardware_GEDF_Scheduler: is a hardware implementation in VHDL (targeting FPGAs) of the G-EDF multiprocessor scheduling policy.
cMIPS - an FPGA ready VHDL model for 5-stage pipeline, MIPS32r2 core
This project was moved to https://gitlab.c3sl.ufpr.br/roberto/cmips The code here is no longer up to date. The VHDL model mimics the pipeline design described in Patterson & Hennessy's book (Computer Organisation and Design) and is an almost complete implementation of the MIPS32r2 instruction set. The TLB and assorted control registers will be included soon (as of fev 2015). The model was synthesized for an Altera EP4CE30F23. The model uses up 15% of combinational blocks and 5% logic registers.
The ixo.de USB JTAG pod and firmware allows to access JTAG-capable chips via USB and a protocol like Altera USB-Blaster.
