This paper proposes a multi-chip NoC approach for implementing centralized ECUs. Unlike the conventional approach where ECUs and sensors/actuators are connected tightly, it has potential to implement efficient and reliable systems for automotive applications. Then, this paper reports our experience of implementing our first chip designed for the multi-chip NoC platform, and shows some experimental...
Network-on-Chip (NoC) is now considered to be a promising approach to implementing many-core systems and some real-time applications are executed on them. However, it has not yet been proven that on-chip networks can theoretically satisfy the hard real-time constraints. In this paper, we propose the worst-case performance models of on-chip networks which represent the upper bound latency between NoC...
This paper proposes dependable routing algorithms for multi-chip NoC platforms. In a multi-chip NoC platform, multiple NoCs are connected via off-chip links, and on-chip networks are seamlessly extended to a multi-chip network. Such platforms have several potential advantages in embedded systems with many cores, such as automotive control systems. One limitation of this approach is that the extended...
Network-on-Chip (NoC) is considered to be a promising approach to implement many-core systems and a large number of on-chip router optimization studies have been proposed. In this paper, we propose to dynamically adjust link-width of each port on a router optimized to spatially biased traffic. Different from the previous No Coptimization approaches, in which the optimization is almost performed in...
Network-on-Chip (NoC) is now considered to be a promising approach to implementing many-core systems. In this paper, we propose fully asynchronous on-chip networks which have improved tolerance against stuck-at-faults, aging degradation faults and transient faults, as well as potential of high performance. We have developed a dependable routing algorithm to detour a faulty router or a faulty link...
