We see both, homogeneous and heterogeneous multi-core designs. Symmetric Multiprocessing (SMP) enables high performance computing on embedded systems for applications that require high processing power. However, parallel programming of multi-core embedded applications suffers from complexity. It is notably harder, time-consuming and most importantly, prone to errors than sequential programming which makes it a challenge, particularly in safety critical domains. In avionics, the position paper CAST-32A Multi-core Processing reports on concerns and proposes objectives regarding the safety for multi-core software. The key is to identify and prevent possible interference that potentially disturbs the determinism. Rust is a modern systems programming language which aims amongst others at being safe. In this paper, we investigate how Rust can help with the development of safe multi-core applications, in particularly for the avionics domain. A representative platform is designed with a partitioned runtime environment using the L4Re separation kernel on a multi-core ARM architecture. The evaluation is carried out using a parallel implementation of a forward looking terrain avoidance algorithm. 收起
