In modern circuits the fraction of total power attributed to wires is increasing. One method to decrease the power consumption is to reduce the number of transitions on long bus wires by encoding bus traffic. The presented circuit reduces the energy consumed by buses on a single die by caching the eight most recent values on both sides of a long bus and transmitting a low weight code word on a ...

A growing number of control systems are distributed and based on the use of a communication bus. The distributed nodes execute periodic tasks, which access the bus by releasing the messages using a priority-based mechanism with the goal of minimal message response times. Instead of randomly accessing the bus, a dynamic scheduling of messages technique based on adaptation of time offsets between...

In providing a review of the Australian bus industry, this paper describes some of the key issues that are affecting route bus public transport; a complex array of stakeholders and a key tool – the route bus – which exhibits considerable variation in specification. Information gathered by empirical means and through literature suggests that the stakeholders are many, their roles complex and int...

Cache only memory architecture has the potential to decrease global bus traffic in shared-bus multiprocessors, thereby reducing the speed gap between modem microprocessors and global backplane bus systems. However, the (huge) size of attraction memory (AM) in each processor node makes it difficult to properly match the access time of its state and tag storage to the bus cycle. This becomes a se...

With the rapid increase in the complexity of chips and the popularity of portable devices, the performance demand is not any more the only important constraint in the embedded system. Instead, energy consumption has become one of the main design issues for contemporary embedded systems, especially for I/O interface due to the high capacitance of bus transition. In this paper, we propose a bus e...

Bus systems are naturally unstable. Without control, the slightest disturbance to bus motion can cause buses to bunch, reducing schedule reliability. Holding strategies can eliminate this instability. However, the conventional schedule-based holding method requires too much slack time, which slows buses. This delays on-board passengers and increases operating costs. This paper studies a family ...
