4 Technical Data
– 667 MHz Dual Core Processor exclusively for customer code execution (MATLAB
based)
– Identical, dedicated 667 MHz Dual Core Processor exclusively for logging purposes
– High Speed Logging 200 kHz of 6 analogue inputs (optional)
– Real time Ethernet SERCOS 3
– Event logging, Configurable pre-event logging
The Vehicle Control Unit VCU is a highly powerful processing unit for customer-developed
functions integrating a flexible logging device with high speed logging capability of up to
200 kHz.
The processing cores feature floating-point arithmetic and a high-end FPGA for ultimate
performance and flexibility. The customer software development process is based on
MATLAB/Simulink to significantly speed up algorithm development (automatic code and
documentation generation).
It offers real time Ethernet functionality to exchange e.g. data used in control algorithms
between devices (guaranteed latency time 1 ms).
This device comes with a basic software consisting of operating system, H/W-drivers and
low-level functions like pin setup, diagnostics, etc. The customer can freely develop his
own application software using the MATLAB/Simulink environment.
