Real-Time Application Interface (RTAI) Now Supports PPC and 2.4 Kernel

New PPC and 2.4 Kernel Support Added to Real-Time Application Interface for Linux

Technical Bulletin July 20, 2000

The Real Time Application Interface (RTAI) development team led by Paolo Mantegazza of Dipartimento di Ingegneria Aerospaziale Politecnico di Milano (DIAPM) has announced the beta release of RTAI version 24.1.0. RTAI's rich set of core services, combined with its many features and the development tools developed and funded largely by Lineo's Industrial Solutions Group (formerly Zentropix) provide what many believe to be the foremost real-time Linux development and deployment solution.

The most notable items of this new version are its support for the PowerPC (PPC) architecture and for the Linux 2.4 kernel. Additionally, the file structure has been optimized in order to make porting to different architectures a simpler matter.

Today's RTAI provides a competitive and quickly growing list of features including:

--Traditional RTOS IPCs: Semaphores, mailboxes, mutexes, condition variables, FIFOs, shared memory, and RPCs
--UniProcessor and SMP (x86) support
--FPU support
--One-shot and periodic schedulers
--x86 family CPU support
--Motorola PowerPC CPU support
--Linux kernel 2.4 support

RTAI distinguishes itself from other real-time Linux solutions by providing:
** POSIX 1003.1c compatibility - allows programming from a common, fully portable API
** Dynamic Memory Allocation - allowing you to, for instance, create one real-time task from another.
** PERL Bindings - allowing simplified soft real-time programming from a scripting environment.
** /proc interface - providing detailed information on the scheduler, FIFOs, interrupts, and memory manager.
** LXRT - allowing the development and deployment of hard real-time applications within standard user space.
