UDE adds multi-core debug support for ST’s Stellar P3E MCU| Electronics Weekly

This is ST’s first automotive MCU with an integrated AI accelerator, PLS highlights.

Specifically, the Stellar P3E features a multi-core cluster of Arm Cortex-R52+ CPUs and a Neural Processing Unit (NPU). This is for the development of powertrain architectures and to consolidate motor controllers, inverters, OBCs, and DC-DC converters into unified systems for hybrid and electric vehicles.

And for this, PLS has expanded the debug, trace and test tool UDE Universal Debug Engine to enable developers to perform multi-core debugging for the MCU part of the device.

The company writes:

“All cores of the Cortex-R52+ multicore cluster are visible within a common, unified debugger instance and can be controlled from within it. The UDE Multi-Core Run Control ensures full synchronization of all cores during debugging at all times. Depending on the use case, the cores can also be started and stopped individually.”

“Multi-core breakpoints…simplify the debugging of complex applications. Such a breakpoint is always effective and completely independent of which core is currently executing the respective code.”

Note, however, series production is not due to begin until late 2026. But there will be access to UDE functions for debugging, testing, tracing, and system analysis tailored to the Stellar P3E MCUs. This will be for customers and early adopters via the ST Partner Program.

You can read more information about the UDE on the PLS website.

The headquarters of Programmable Logic & Systems are in Lauta, Germany.
