64-Bit Linux-Based RTOS for SCALEXIO Systems

As part of our continuous improvement strategy, dSPACE introduced a 32-bit Linux-based real-time operating system (RTOS) for SCALEXIO Processing Units and DS6001 Processor Board with the dSPACE Release 2020-B.

With dSPACE Release 2022-A, a 64-bit Linux-based RTOS has been introduced as the default RTOS of the SCALEXIO processing hardware, while the 32-bit Linux-based RTOS was available as legacy support. 

The migration to the 64-bit Linux-based RTOS provides you with

• Improved real-time execution and computational performance, which is especially relevant for autonomous driving and e-mobility applications
• Faster deployment of new dSPACE features
• Improved support of memory-intensive applications, e.g., high bandwidth network communication
• More straightforward third-party software support

Migrating to the 64 bit Linux-Based RTOS

When migrating to dSPACE Release 2022-A or later, the following items built for earlier dSPACE Releases are no longer compatible with the SCALEXIO system and must be (re-)built from source code:

• Real-time applications (.rta)
• SIC and BSC files
• Binary libraries contained in model containers (e.g., SIC, BSC, FMU files)
• Binary libraries referenced by Simulink models (e.g., by S-functions)
•  Binary libraries referenced by ConfigurationDesk applications via custom code settings or custom I/O functions

Source code is expected to be reusable in most cases. Cases that might require an adaptation of C code are related to custom code that expect specific word lengths for unqualified integer types (e.g., long) or pointers.

Discontinuation of the support for 32 bit Linux-Based RTOS for SCALEXIO Systems

Since the 64-bit Linux-based real-time operating system (RTOS) will be the future RTOS for all SCALEXIO Processing Hardware, the legacy support of the 32-bit version will be discontinued after dSPACE Release 2023-A. From dSPACE Release 2023-B onwards, only the 64-bit RTOS will be provided.
