REDSonic’s REDICE-Linux is a real-time Linux kernel that combines hard real-time scheduling and a preemptible kernel with the ultra low latency support of RTAI in one complete hard real-time Linux kernel.
REDICE-Linux is the ideal embedded OS for building Internet appliances, network devices, medical devices, industrial applications, data acquisition, machine control, and other mission- and time-critical applications which require guaranteed quality of service (QoS).
REDICE-Linux also comes with a complete software development kit (SDK) and tool chain for rapid embedded system development.
Some of the specific real-time and embedded features of REDICE-Linux include: · Supports Linux 2.4.x and 2.2.x kernels · Preemptible kernel · Sub-millisecond latency for user space programs · Ultra low latency (50msec) for kernel space programs · Flexible, two-component real-time scheduler · High-resolution microsecond timer · Precise performance measurement and control · Powerful event monitor and interrupt handling · Compatible with standard Linux applications · Supports most popular embedded platforms · Dynamic performance refinement and assurance
