Virtual Prototypes – Evaluation Framework for MOST-based ADAS
Fortsetzung des Artikels von Teil 3
Optimization of system parameters
Virtual prototyping can be used to determine optimal configuration parameters according to use case scenarios. The key buffers in the ADAS scenario are located between the MOST device and the applications. The buffers are divided into receive and transmit buffers. The receive buffer utilisation is used as an example. The MOST data handler, which models the rudimentary behaviour of the INIC, extracts/writes the data from/to the MOST frame. The data read is stored in the receive buffer every 20.833 µs. On the application side, the buffer is read with the application interrupt rate. These read and write accesses have to be balanced to avoid buffer overflow and subsequent data loss or retransmissions. In virtual prototypes, it is easily possible to monitor the buffer utilisation, e.g. with different application interrupt rates or with various traffic scenarios that influence the frame utilisation.
