Thanks to recent progresses in optical device integration, nanophotonic interconnect can be applied to build optical network-on-chip (ONoC) for providing connectivity among increasing number of cores and memory modules in future many-core processors. However, there are still challenges in architecture and protocol design of ONoC for massive parallel memory accesses in CMPs, The on-chip memory access...
Nan photonic interconnects have recently emerged as a promising candidate for on-chip communication in future chip multi-processors (CMPs), by providing high bandwidth chip wide communication at low latency and power overhead. Optical electrical interfaces are important components in an optical NoC (ONoC), whose role lies in transporting data packets from the network interfaces (NIs) of local processing...
This paper tries to optimize the placements of data pages, which have a strong impact on system performance. We find that both core-to-memory distance and contention on MCs and interconnects are critical. Migrating pages to their page access center can mini-mize average memory access distance, but may cause serious contention and congestion, necessitating further schemes for load balancing. Based...
Network-on-chip (NoC) has recently emerged as a primary paradigm for interconnecting ever increasing number of on-chip cores in future chip-multiprocessors (CMPs). As the advent of big data era, high volume of traffic injection, combined with the ever-changing patterns will exert severe pressure on some hotspots, leading to serious traffic congestion. These hot nodes will exhaust up the communication...
Distributed Routing Model (DRM) and Centralized Routing Model (CRM) are two mainstream routing models for Network-on-Chip (NoC). DRM is scalable and efficient, but its state learning is costly because exchanging network state must be in flooding form which may consume large amount of bandwidth. CRM monitors and send real-time network state to a central routing node as the basis of routing path computing...
Recently proposed technologies to enhance NoC performance can be applied to only part of the network to save hardware overhead and energy. This paper discussed the influence of network traffic distribution to local optimization efficiency. We introduce two-dimensional finite difference method to quantize the non-uniformity of the NoC traffic. Then, we describe hotspot and potential optimization node...
As the scaling of integration, massive remote communication has become the main bottleneck of system performance for network-on-chip (NoC). Most packets have to travel long distances from source to destination, leading to long latency and severe contention. Hybrid Wireless NoC(HWiNoC) has emerged as a popular method to handle remote transmission in NoC, in which packets can be modulated to wireless...
By exploiting deeply the memory-level and communication-level parallelisms provided by multiple memory controllers (MCs) and interconnect components, NoC-based on-chip distributed memory systems (DMSs) have received great attention to hit the great 'memory wall'. System scaling makes memory access distance and massive contention found in MCs and interconnects critical to system performance. Data replication...
