Real-time frameworks/RTOS based on active objects & state machines
Real-time frameworks/RTOS for building responsive and modular real-time embedded software as systems of active objects (concurrent state machines). The QP family consists of QP/C, QP/C++, and QP-nano frameworks, which are all strictly quality controlled, superbly documented, and commercially licensable. The behavior of active objects (a.k.a. actors) is specified in QP by means of hierarchical state machines (UML statecharts). The frameworks support manual coding of UML state machines in C or C++ as well as automatic code generation by means of the free QM modeling tool. All QP frameworks can run on bare-metal MCUs, completely replacing a traditional RTOS. Ports and ready-to-use examples are provided for major embedded CPUs, such as ARM Cortex-M, ARM7/9, MSP430, as well as Arduino and mbed. QP/C and QP/C++ can also work with a traditional RTOS/OS, such as ThreadX, FreeRTOS, embOS, and uC/OS-II as well as Linux (POSIX), Windows.

Arbitrary-precision CRC calculator and algorithm finder
CRC RevEng is a portable, arbitrary-precision CRC calculator and algorithm finder. It calculates CRCs using any of the 102 preset algorithms, or a user-specified algorithm to any width. It calculates reversed CRCs to give the bit pattern that produces a desired forward CRC. CRC RevEng also reverse-engineers any CRC algorithm from sufficient correctly formatted message-CRC pairs and optional known parameters. It comprises powerful input interpretation options. Compliant with Ross Williams' Rocksoft(tm) model of parametrised CRC algorithms.
Polycrystal generation and meshing.
Neper is a software package for polycrystal generation and meshing. It can deal with 2D and 3D polycrystals with very large numbers of grains. Its main features are: - Generation of polycrystals from (experimental) morphological properties; - Generation of multiscale microstructures; - Generation of periodic or semi-periodic microstructures; - Meshing into good-quality elements; - Meshing with cohesive elements at interfaces; - Visualization and analysis of the tessellations and meshes. Neper is built around three modules: generation, meshing and visualization. All the input data are prescribed non-interactively, using command lines and / or ASCII files. Neper can be compiled and run on any Unix-like system.

PyRPL turns your Red Pitaya into a powerful analog feedback device.
The Red Pitaya is a commercial, affordable FPGA board with fast analog inputs and outputs. This makes it useful for quantum optics experiments, in particular as a digital feedback controller for analog systems. Based on the open source software provided by the board manufacturer, PyRPL (Python RedPitaya Lockbox) implements many devices that are needed for optics experiments with the Red Pitaya. PyRPL implements various digital signal processing (DSP) modules (see features below). It allows to arbitrarily interconnect the available DSP modules and retrieve signal values on timescales below 1 ms. The graphical user interface (GUI) provides a realtime display of the various measurement instruments and allows the easy configuration of DSP signal chains and feedback controllers. At the highest abstraction level, arbitrary feedback sequences can be defined to fulfill tasks as complex as approaching and locking a resonance of a high-finesse Fabry-Perot cavity (tested up to finesse=100,000).

Computes Accurate Fourier Transform via Explicit Integration not FFT
Fourier transform methods are used to analyze functions and data sets to provide frequencies, amplitudes, and phases of underlying oscillatory components. Fast Fourier transform (FFT) methods offer speed advantages over evaluation of explicit integrals (EI) that define Fourier transforms. It has been shown recently that EI methods can be more accurate than FFT methods (Courtney and Courtney, A More Accurate Fourier Transform) for scientific data analysis and that EI methods can be implemented in reasonable times with modern computing power. This project makes the source code (and command line Windows executable) developed in that study openly available for scientific and engineering uses.

Schematic circuit editor for VLSI and Mixed mode circuit simulation.
Xschem is a schematic capture program, it allows to create a hierarchical representation of circuits with a top down approach . By focusing on interconnections, hierarchy and properties a complex system (IC) can be described in terms of simpler building blocks. A VHDL, Verilog or Spice netlist can be generated from the drawn schematic, allowing the simulation of the circuit. Key feature of the program is its drawing engine written in C and using directly the Xlib drawing primitives; this gives top speed performance, even on very big circuits. I have succesfully managed to simulate complete VLSI projects with this tool, both digital (Verilog / VHDL) and analog (Spice). The user interface is built with the Tcl-Tk toolkit, tcl is also the extension language used to send commands to the program. Schematics can be printed in SVG, PNG, PDF, formats. XSCHEM runs on Linux or other Unix-likes with Xorg server and on Windows with the Cygwin layer and required tools installed.
