Check yafu on github for the latest code. YAFU (with assistance from other free software) uses the most powerful modern algorithms (and implementations of them) to factor input integers in a completely automated way. The automation within YAFU is state-of-the-art, combining factorization algorithms in an intelligent and adaptive methodology that minimizes the time to find the factors of arbitrary input integers. Most algorithm implementations are multi-threaded, allowing YAFU to fully utilize multi- or many-core processors (including SNFS, GNFS, SIQS, and ECM). YAFU is primarily a command-line driven tool. You provide the number to factor and, via screen output and log files, YAFU will provide you the factors. There is also an interactive environment similar to MATLAB or PARI/GP, where you can type commands and store results. YAFU is very customizable, through the optional use of many many command line parameters and a very capable expression inter

PICSimLab is a realtime emulator of development boards with MPLABX/avr-gdb debugger integration. PICSimLab supports microcontrollers from picsim, simavr, uCsim, qemu-stm32, qemu-esp32, and gpsim. PICSimLab has integration with MPLABX/Arduino IDE for programming the microcontroller's boards. As the purpose of PICSimLab is to emulate real hardware it does not have any source code editing support. For code editing and debugging the same tools used for a real board should be used with PICSimLab, such as MPLABX, Arduino IDE, or VSCode with PlatformIO. PICSimLab supports several devices (spare parts) that can be connected to the boards for simulation. Such as example LEDs and push buttons for simple outputs and inputs and some more complex ones like the ethernet shield w5500 for internet connection or the color graphic display ili9340 with touchscreen. The complete list of parts can be accessed in the documentation. Documentation at https://lcgamboa.github.io/picsimlab_docs/stable/

What is it? It's a Bootloader for Microchip, Atmel, NXP, TI and 8051 devices. A Bootloader is a firmware running in the microcontroler device which allows the user to send it's own firmware without the need of a programmer. This Bootloader consists of: - firmwares for many devices (this firmware need to be send to the device's flash memory with a programmer, only once) - a PC software which communicates with the bootloader firmware in the device and send the user's program in its memory Where does it come from? This Bootloader is based on "Tiny PIC Bootloader" made by Claudiu Chiculita. A special THANK to him!!! What can it do? It can program: - Microchip PIC10/12/16/18/24/32/dsPIC30/33 - Atmel ATtiny, ATmega - TI MPS430 - NXP ARM Cortex-M0+ - Silicon Labs C8051 And this: - with light modifications to the Bootloader firmware for new devices - without modifying your source code or using a special linker script - via GUI or command line prog - with automatic Reset

OpenPFGW is software that is designed to perform PRP and primality tests on numbers of specific forms. This software currently run on any x86 hardware with the support of George Woltman's gwnum library, the same library behind GIMPS and Prime95.

LinAsm is collection of very fast and SIMD optimized assembly written libraries for x86-64 Linux. It implements many common and widely used algorithms for array manipulations: searching, sorting, arithmetic and vector operations, unit conversions; fast mathematical and statistic functions; numbers and time converting algorithms; finite impulse response (FIR) digital filters; spectrum analysis algorithms, Fast Hartley transformation; CPU cache friendly functions and extremely fast abstract data types (ADT) such as hash tables b-trees, and much more. LinAsm libraries are written on FASM assembly language. They are stable and have appropriate benchmarks for many units. All libraries are well documented and grouped by their functionality. To get more information about this library, please visit the official web site: http://linasm.sourceforge.net

This project has been moved to http://pros.cs.purdue.edu/ PROS is a lightweight and fast alternative operating system for the VEX Cortex Microcontroller. It features multitasking, low-level control, and Wiring compatible functions to harness the full power of the Cortex. With a real-time kernel based on FreeRTOS and a development environment built on Eclipse CDT, PROS uses proven software to increase the reliability and usability of the VEX development system across all three major computing platforms. PROS is currently under active development to make it usable for VEX high school and middle school teams. PROS is intended for advanced VEX users seeking to move beyond competing environments. Eclipse and FreeRTOS have their own licensing agreements. Please see http://www.eclipse.org/legal/epl-v10.html and http://www.freertos.org/a00114.html for details.

PPMScope is a do-it-yourself oscilloscope with an open source design. The intent is that the project can be constructed by an electronics hobbiest using the instructions included. The design is a compromise between features and cost. The bandwidth is lower than a commercial scope, so it's use is limited to signals of 500 kHz and below. It's sample buffer is also smaller than a commercial scope, however sufficient for most oscilloscope functions. This is a version based on the PIC16F877A microcontroller running with a 20MHz clock. The maximum sampling rate is 1 MHz with a 5 Mhz equivalent sampling mode. Currently, the computer interface supports USB, serial, and parallel ports. Good luck on the construction and I hope you enjoy your oscilloscope. I am happy to answer any questions or provide technical support for this design.

FastFlow is a C/C++ programming framework supporting the development of pattern-based parallel programs on multi/many-core, GPUs and distributed platforms. FastFlow run-time is built upon non-blocking threads and lock-free queues. Thanks to its very efficient CAS-free communication/synchronization support (e.g. few clock cycles core-to-core latency), FastFlow effectively supports the exploitation of fine grain parallelism, e.g. parallel codes managing very high frequency streams on commodity multi-core. FastFlow works on x86, x86_64, PPC, ARM, and Linux, Mac and Win XP/7. From Jan 1, 2018 code development migrated on GitHub at https://github.com/fastflow/fastflow
