Support for rendering multimedia at digital vehicle instrument cluster

Smart cars have become increasingly used lately. One of the most important aspects is safety, both people and vehicles. Functional safety is introduced as a special term, where it is necessary to define the risk as well as the undesirable effects of certain hazards. The particular challenge is that two applications, one for the cluster and the other for the head-unit, are executed on single board with two operating systems via hypevisor. The main problem is in the communication between the cluster and the head-unit, because the cluster falls under the ISO26262 standard which is specifically written for the automotive industry. This paper presents the solution of the problem through the implementation of a middleware for controlling and sending messages from head-unit to cluster.
