Upcoming Webinar: CoreDX DDS - Enhancing the Python Ecosystem

November 8, 2022 at 9am MST

The Python programming language is simple, free, easy to use, and is becoming increasingly popular across a variety of academic and commercial domains, including web development, data analysis, and artificial intelligence. With numerous libraries and frameworks available, Python can be used to rapidly prototype any kind of software.

CoreDX DDS is a robust, easy to use, flexible, and secure cross platform communication middleware. Integrating the high performance CoreDX DDS infrastructure into the Python environment brings a powerful development tool into the Python toolset.

Join us to learn about the CoreDX DDS Python API, including live demonstrations with code examples. We'll show you how easy it is to use Python to publish DDS topics.

CoreDX DDS Tips & Tricks

Welcome to this month's edition of CoreDX DDS Tips & Tricks, where our engineers provide quick bits of information to help our customers.

Sequences and strings - bounded or unbounded?

CoreDX DDS provides both bounded and unbounded strings and sequences for use in application defined data types.

With CoreDX DDS, unbounded strings and sequences are truly unbounded - the application can dynamically size and add to these data types, and memory will be allocated as necessary to hold the data. This means a sample containing a 10-byte string will use less memory than a sample with a 100-byte string. Not all DDS implementations offer these truly unbounded data types.

Bounded strings and sequences are considered fixed-size data types. If a DataWriter or DataReader's data type contains all fixed-sized components, CoreDX DDS may be configured to preallocate memory for the writer or reader's data cache, increasing performance.

CoreDX DDS allows the application developer to choose between the flexibility of unbounded data types and the deterministic and real-time performance of fixed sized and bounded data types. When designing your data types, you are free to choose the data types best suited to each particular Topic and application.

CoreDX DDS Tips & Tricks are intended to be useful for engineers using CoreDX DDS. If you have any questions, please contact us here.
