WLA DX is yet another macro assembler that can program the GB-Z80, Z80, 6502, 65c02, 6510, 65816, HuC6280, and SPC-700 CPUs. Included in the package there is a GB-Z80 disassembler and few converters. WLA DX was initially programmed to compile ROM images for Gameboy, but nowadays it can also patch existing ROM images with code, and even compile program files and ROM files for other CPUs like the NES-6502, C64-6510, and SNES's SPC-700.
Aasm is an advanced modular assembler designed to support several target architectures. It has been designed to be easily extended. Its global architecture takes advantages of dynamic libraries to provide input, assembler and output modules. The input module supports Intel syntax (like nasm, tasm, masm, etc.). The x86 assembler module supports all opcodes up to P6 including MMX, SSE and 3DNow! extensions. F-CPU and SPARC assembler modules are under development. Several output modules are available for ELF, COFF, IntelHex, and raw binary formats. Advanced features include symbol scopes, an expressions engine, big integer support, macro capability, and numerous and accurate warning messages (over 300).
KMD is a multi-processor debugger. It can debug with hardware boards over serial ports or with software emulators (ARM and MIPS emulators are included in the project). Using the pipe option you can debug over the network or any other communication medium. It can load many executable formats such as ELF, and display and follow the original source even from multiple source file programs. There is support for breakpoints and watchpoints which can trap on specific data (such as loading or executing specific instructions). Support for other features such as FPGA's is also available, allowing loading or any control required to drive a specific hardware device. The project uses chump to allow disassembly and line assembly. Chump also allows new architectures to be easily added without the need to recompile the system. Communication with the backend is done using two pipes/fifos using a simple set of codes. Back end communication program can be created using very little memory on the target device.
ProjectCenter is GNUstep's integrated development environment (IDE). It assists you in starting new projects and lets you manage your project files using a intuitive and well ordered graphical user interface. ProjectCenter automatically creates the project makefiles and aids you in the process of editing, project compilation, package building, and debugging.
J51 is a Intel MCS51 emulator with all the standard integrated peripherals. A disassembler with an integrated debugger is also included. Standard peripherals emulated are Timer 0/1 (Mode 0, 1, 2, and interrupts), serial interface in polled and interrupt mode, standard I/O, and ports 0 to 4. Microprocessors emulated are the Intel MCS 8051 (no peripherals), Intel 8051, Intel 8052, Philips LPC674, and Philips LPc900.
The HLA Standard Library was developed to support the High Level Assembler (HLA), but could be used with other assemblers or higher-level languages if the necessary headers were developed. It supports 32-bit versions of Windows, Linux, Mac OS X, and FreeBSD, and is written entirely in HLA. It includes the following modules: args, arrays, bits, chars, console, conversions, cset, date, environment, exceptions, file class, file I/O, filesys, lists, math, memory-mapped files, patterns, RNG, stderr, stdin, stdout, strings, tables, time, timer, zstrings, sockets, threads, and blob. An automated test suite is included.
