Recipe For An RTOS
BitBake from the OpenEmbedded project is central to Monta Vista’s latest Linux real-time operating system (RTOS) and system tool release, Monta Vista Linux 6 (MVL 6). MVL 6 has the latest Linux and Eclipse development system enhancements and bug fixes, but the BitBake build environment is being exposed in this release. BitBake is a system designed to build systems, sort of like a super make facility. In fact, it is designed to work with standard make tools like Ant.

September 25, 2008 Lucid Pulls A PCI Express Graphics Switch
The Hydra 100 from Lucid Technologies turns two or more graphics adapters into a single, cooperative graphics compute engine. It starts as a basic PCI Express switch, allowing any kind of device to be plugged in downstream. But it shows its multifaceted personality when GPUs such as those from NVidia and AMD/ATI are downstream. Its RISC engine makes multiple graphics boards appear as a single, more powerful device, distributing graphics operations...
