Free real-time Linux project achieves stable release

Mar 30, 2004 — by LinuxDevices Staff — from the LinuxDevices Archive — 1 views

A project to produce a free, dual-kernel, real-time Linux distribution has achieved its first stable release. The Open Components for Embedded Real-time Applications (OCERA) project's 1.0.0 release supports real quality of service scheduling, CAN bus systems, and fault-tolerant and real-time Ethernet, along with standard Linux functionalities.

OCERA 1.0.0 is based on a modified Linux 2.4.18 Linux kernel, in which scheduling has been modified to provide bandwidth reservation scheduling, according to OCERA's Adrian Matellanes. That means that, “Your video doesn't suffer from intense activities,” he says.

The release also includes version 3.2 of the RTLinux-GPL kernel “greatly enhanced,” according to Matellanes, “to provide a lot of new real-time features like barriers, dynamic memory allocation, POSIX signals and POSIX trace, and a new scheduling system allowing bandwidth reservation.”

The release contains drivers for CAN bus systems, a real-time Ethernet implementation using a “Publisher/Subscriber” algorithm, and support for developing fault tolerant applications.

A tarball is available for download from SourceForge. Development releases are available from CVS.
