The throughput of a Network-on-Chip (NoC) mainly depends on the specific router microarchitecture design. Besides, coordination among routers also plays an important role in the performance of NoC, since router behaviors are closely related, especially between neighbors. In this work we focus on such strong tie between neighbor routers and propose a novel router microarchitecture design with neighbor...
With an increasing trend to implement Network-on-Chip (NoC)-based Multi-Processor Systems-on-Chips (MPSoCs), NoCs need to have guaranteed services and be dynamically reconfigurable. Many current NoCs consume too much area and cannot support dynamic reconfiguration. In this paper, we present an area-efficient Spatial Division Multiplexing (SDM)-based NoC. We replaced area consuming 32-bit to M-bit...
With the emergence of on-chip networks, the power consumed by router buffers has become a primary concern. Bufferless flow control addresses this issue by removing router buffers, and handles contention by dropping or deflecting flits. This work compares virtual-channel (buffered) and deflection (packet-switched bufferless) flow control. Our evaluation includes optimizations for both schemes: buffered...
Network-on-chip (NoC) architectures are fast becoming an attractive solution to address the interconnect delay problems in chip multiprocessors (CMPs). However, increased power dissipation and limited performance improvements have hindered the wide-deployment of NoCs. In this paper, we combine two techniques of adaptive channel buffers and router pipeline bypassing to simultaneously reduce power consumption...
