System-level thermal management techniques normally map applications on non-adjacent cores to guarantee the safe temperature in many-core systems, while the communication efficiency will be oppositely affected by long-distance data transmission over conventional Network-on-Chips (NoC). SMART NoC has enabled single-cycle multi-hop bypass channels between distant cores, which can significantly reduce...
Network on Chip (NoC) has become a promising solution for the communication paradigm of the next-generation multiprocessor system-on-chip (MPSoC). As communication has become an integral part of on-chip computing, researchers are paying more attention to its implementation and optimization. Traditional techniques that model inter-processor communication inaccurately will lead to unexpected runtime...
To satisfy the ever increasing performance requirement of applications, Multiprocessor System-on-Chip (MPSoC) plays an irreplaceable role in embedded system these days. It is significant to effectively optimize communication for achieving maximum parallelism on MPSoC, especially on Network-on-Chip (NoC) based architectures. The problem of how to make an arbitration of communication congestion is remained...
Multiprocessor System-on-Chip employing self-timed technique becomes increasingly attractive due to its ability for exploiting high parallelism of applications. There have been many research efforts on studying self-timed techniques on hardware layer. However, these research results are unable to be applied to system synthesis; in particular, how to correctly and optimally map an application represented...
With the increasing power density and numberof cores integrated into a single chip, thermal managementis widely recognized as one of the essential issues in Multi-Processor Systems-on-Chip (MPSoCs). An uncontrolled temperaturecould significantly decrease system performance, leadto high cooling and packaging costs, and even cause seriousdamage. These issues have made temperature one of themajor factors...
Wireless Sensor Networks (WSN) are often densely deployed in the region of interest in order to continuously monitor physical phenomenon. Due to highly deployment density and the nature of the physical phenomenon, nearby sensor readings are often highly correlated in both space domain and time domain. These spatial and temporal correlations bring significant potential advantages as well as challenges...
It is known that distributed power control in wireless ad-hoc networks is challenging, due to the inherent global coupling between concurrent transmissions interfering with each other. Observing that the globally optimal point lies on the boundary of the feasible region, we transform the utility maximization problem into a more structured problem in the form of maximizing the minimum weighted utility...
Today's mobile devices support many wireless technologies to achieve ubiquitous connectivity. Economic and energy constraints, however, are driving the industry to implement multiple technologies into a single radio. This system-on-a-chip architecture leads to competition among networks when devices toggle across different technologies to communicate with multiple networks. In this paper, we study...
