The Sierra hardware RTK component together with its API (Application Programmers Interface) makes a complete real-time kernel and can be used stand-alone or as a hardware accelerator for commercial OS. Easy integrated as an IP core with a defined interface.

- Introduction and background to Sierra concept – (627kb)

Key Features:

ö A Complete Real-Time Kernel (RTK) »
A unique solution, implemented in hardware, which use the mass parallelism in hardware. Scheduler, time queues etc. in hardware.

ö A tiny footprint in memory »
With a user-friendly application programmers interface in C. The footprint is very small since the functionality is placed in hardware instead.

ö Time predictable and Performance Enhancing »
The hardware kernel works in parallel to the CPU. With speed-up and less overhead and jitter as a result. The most service calls to Sierras takes 2-4 clock cycles to execute. Deadline control under run time in hardware for periodic tasks. No clock tick administration overhead.

ö Easy system integration »
Faster time to market (FPGA).

ö Enhanced performance and security »
Simplifies real-time analyze and behaviorally safe in hardware.

ö Smart Period task with deadline control in hardware

ö Flexible and new possibilities »
Simple to add on new advanced functions to Sierra framework.

ö Support and courses »
Theory and practical training.

ö Results from more than 20 years research!
