AmigaOS Features
Listed below are the modules that make up the core of AmigaOS 4. Most of the OS modules (including the kernel) are finished and being tested internally by the OS 4 development team.
Current work centers around Intuition and Reaction, 2D/3D drivers, A1 Bios, additional kernel functionality (virtual addressing and page-based memory handling) and the integration of the 68K emulation into the system.
Here are the modules that make up AmigaOS 4:
Exec Second Generation (Exec SG)
Exec is the AmigaOS kernel and was written in 68K assembly for AmigaOS 3.1. It has been rewritten in C, as ExecSG, for AmigaOS 4.
The following features are planned for ExecSG:
Hardware abstraction layer (HAL)
Virtual addressing (for automatic stack enlargement etc.)
Page-based memory handling (less fragmentation and more efficient)
Virtual memory
New library interface
Resource tracking and management
Optional memory protection
WarpOS backwards compatibility
Just in Time (JIT) 68K emulation
PPC native TCP/IP stack & PPP drivers
fastest on the platform
Re-implementation of the Amiga file system (FFS2) for PPC
PPC native CD Filesystem
with limited Mount Rainier support (use your CDRW as a floppy)
Recovery and Salvage tools for FFS2 and SFS
PPC native CD back-up tool
OS 4 will include a simple tool which allows the user to back-up files by burning them to an ISO 9660 CD which also allows for exchanging data between systems)
PPC native RTG system
Picasso 96 V3
PPC native arithmetically optimised version of layers.library

PPC native RTA system based on AHI
with Soundblaster Live! Drivers
PPC native GUI system (Intuition and Reaction)
PPC native shell
PPC native version of "Amidock"
PPC native utility for archiving and de-archiving
SCSI drivers for onboard (UW) SCSI controllers
AmigaInput API (for multimedia controller devices)
USB stack
already adapted for the Highway and Subway hardware
PPC native datatypes
New HDToolbox ("Media Toolbox")
Support for TrueType/OpenType fonts
Web-browser (Ibrowse 2.3)
MUI PPC (for legacy applications)
Reading/printing of PDF files
PPC native rewrite of DOS library
PPC native movieplayer
"Action" with DivX and MPEG4 support
PPC native devices
Generic PPC native PCI library
