Open Source Assembly Software - Page 76

A simple absolute mode assembler for 6800/6801. Handles the complete published set of opcodes/mnemonics. Mostly source-language compatible with the common assemblers in use circa 1985, but no macros. Now uses standard LDAA syntax by default. Produces basic S1/S9 object files and assembly listings, and now binary and MC-10 compatible cassette images. (This is for the 8-bit 6800, not the 16/32 bit 68000/coldfire processors.)

avOS Aims to be a replacement for the archos AV300 O/S firmware. This will either be achieved by porting linux to the Archos, writing a custom O/S from scratch, or writing a custom JVM from scratch. The Archos AV300 uses a TMS320DSC25 ARM7 based DSP.

Polyphonic music synthesizer running on Atmel AVR. This is an attempt to provide features similar to the Sequential Circuits Prophet-V, though it is likely that only a subset will be attained.

The b0 Programming Language

This is a port of Basic to NASM (B2Nasm) for visual basic.net. Basic to NASM is capable of file handling, output to and input from the console, arithmetic, and variable creation. A good starting point for native compiler creators.

Basicbuilder is a program for the ti83+/84+ calculators. It can package basic programs as apps, from which they can be directly executed.

beetleOS is a small and flexible real time OS for embedded systems with preemptive multitasking. It also provides a lightweight device-driver framework. It is basically programmed for the ARM7 processor architecture but it could be ported to other archit

"bin2uue" is a simple dialog application that allows you to Encode/Decode small (<1MB) binary files,it was designed to fit the needs of Windows users,it combines encoding/decoding in one program with low memory footprint.

A small shell-like Operating System

Blex is platform-independent SDK. supports video,audio,mouse,keyboard,network,timer.

Blob is a boot loader for SA11x0 (StrongARM) platforms. Blob is able to boot a Linux kernel stored in flash or RAM and provide that kernel with a ramdisk (again from flash or RAM).

boXedOS is a from 2 Students developed operating system. Planned is only a shell, not a GUI.

Yet another operating system for the x86 architecture. It is written for the sole purpose of studying operating system theory, and the x86 architecture

It can boot CP/M3, blink some diodes, play some tunes and talks to the Pi5 over GPIO. This was supposed to be nothing more than a practical joke which quite unexpectedly worked out. It is not optimized (never meant to be), the CP/M3 port working on it is very crude and the bit-banging SPI over AY's I/O ports is terribly slow when it comes to accessing the SD Card adapter (C:). There are several awkwardness in the design, e.g., the first occurence of the ~HALT signal is disconnecting ROM, leaving only the RAM to be accessible by the CPU until RESET (actually, it's this feature that made CP/M bootable on it!). Of the 128kB of available RAM, only 96kB can be used, the upper 32kB is always the same (CP/M's BDOS and BIOS are there), the lower 32kB can be banked on and off by the CP/M BIOS. It is being used for the 12kB ramdisk(A:) and for storing the copy of the CCP (CP/M's shell) so it does not need to be loaded from the SD Card. It was more fun than you all think.

bsum is a tiny tool (256 bytes!) that computes the BSD checksum of any file. It requires only a few kilobytes of memory, and is fast even on an 8086-class PC. bsum supports files of any size (as long as your file system is able to handle them). The BSD checksum is displayed in hexadecimal format (ie. four alphanumeric characters, like "C2E1"). bsum is an excellent candidate for veryfing data integrity on systems that are very constrained in terms of disk space, memory or CPU power. Typically, bsum can be used to verify that files transferred by unreliable means arrived intact.

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.

Homeautomation project based on CAN bus network.

The cc3 project provides software for embedded vision systems. Currently, the software runs on the CMUcam3 hardware platform, which is a NXP LPC2106-based board with an onboard CMOS camera and FIFO, MMC interface, serial UARTs, and servo controller.

! This website is discontinued ! The new, improved MiniChameleon is maintained as of January 2014 on github: https://github.com/emsec/ChameleonMini ATXmega based emulator for contactless smartcards, designed and maintained by Embedded Security Group at the Ruhr-University in Bochum.

A driver for a USB arcade input device named petunia as well as the code going onto the petunia's microcontroller.

Choose-OS (chos), is a modular and configurable boot loader for Linux/x86 - a program that is loaded by the BIOS before any operating systems. This program then lets you choose the operating system to boot and possibly enter parameters to it

codecs.org is a project to collect and assemble various tools for optimized codec design and construction.

Colonel intends to be a simplistic microkernel offering capability protected ipc. It's main purpose is of educational nature, it is _not_ meant to be used as microkernel for a "real" OS.
