Klepsydra Technologies

| PRODUCT

‘Miniaturisation’ of High frequency trading techniques.
General purpose library for embedded systems: Robotics, Space, Aerospace, IoT and Self-driving cars.
Platform independent.
Easy to use API and include several development tools.

| Performance Monitoring

Telemetry monitoring tool developed by NASA.
Used in real missions.
Web-based, lightweight.
Klepsydra uses for performance monitoring
Easy to extend.

| Sensor Multiplexer

How does it work?

One big producer of data. Usually large data (image, point cloud, etc)
Several independent consumers. Each can have different rates.
Each consumer will always receive the latest data
Limited amount of memory needed.

Benefits:

Reuse the same sensor (i.e., camera) for multiple uses
Reduce CPU consumption
Reduce software complexity.

| Event Loop

How does it work?

Several independent data providers
One consumer
Data provided sequentially to the consumer
Guaranteed no data losses

Benefits:

‘Absorbs’ parallel processing complexity and therefore, makes software development much easier
Predictable and reliable behaviour
Reduce CPU consumption
Reduce software complexity.

COMMUNITY VS. PROFESSIONAL COMPARISON

Klepsydra Community

Klepsydra Community is licensed under LGPLv3, which allows its use without guarantees or support. It can be used without limitations for non-commercial applications, but also for commercial ones under the specific conditions specified in the license. The open source edition is available here.

Klepsydra Professional

Klepsydra professional is offered for a subscription-fee based on the number of run-time embedded system deployments. As part of the package, the following support elements are included:

Support matrix. List of supported platforms consisting of three factors: processor, compiler and operating system.
Benchmark reports. We publish reports regularly of benchmark tests for the supported platforms.
Certified version of the software for Space and Automotive.

The software is available for a 30-days trial period and can be requested here.

As both editions share the same public interface (API), the transition from Community to Professional is very smooth, with the user simply needing to replace the code and/or distribution files.

The following table shows the technical difference between both products:

	Community	Professional
Modules and Add-ons	Core, Robotics	Core, Robotics, Space
Development tools	Klepsydra Code Generator	Klepsydra Code Generator, Simulink Klepsydra Toolset
Middleware	ROS, DDS, ZMQ	ROS, DDS, ZMQ, ROS2, CAN
Language Bindings	C++	C++, Node, Matlab/Simulink
Support	None	Included
