*Abstract [#s2c909ea]

**English: [#j944bd4c]
The continuous increasing demand for higher performance computing systems and aggressive technology scaling has driven the trend of integrating a large number of cores on a single chip. In future generations of high-performance many-core systems, the efficiency of the communication infrastructure is as important as the computation efficiency of individual cores. Conventional electrical Networks-on-Chip (NoCs) are expected to reach their limits with increasing core counts because of high power dissipation and reduced performance.
As indicated in the latest version of ITRS roadmap, photonic wiring is a promising interconnect paradigm for future system-on-chip (SoC) designs that can provide broadband data transfer rates unmatchable by the existing metal interconnects. When combined with Wavelength Division Multiplexing (WDM), multiple parallel optical streams of data are concurrently transferred through a single waveguide. This contrasts with the Electronic Networks-on-Chip (ENoCs) that require a unique metal wire per bit stream. The key to saving power in on-chip photonic communication comes from the fact that once a photonic path is established, the optical data is transmitted in an end-to-end fashion without the need for buffering, repeating, or regenerating.
The photonic switching/routing techniques, configuration and routing algorithm directly affect the performance and power characteristics of future many-core on-chip Photonic communication. In particular, the control module and the path configuration algorithm, which orchestrate the different electrical control function, play a significant role on how both electrical and photonic resources are utilized. In this dissertation, a set of novel photonic routing algorithms and architectures are proposed for future on-chip optical networks.
First, a new low-latency, non-blocking photonic switch/router (NBPS) and its control module capable of handling all photonic communication configuration tasks is proposed. The proposed approach is based on a new hybrid spatial switching mechanism for the photonic data stream transfer and is done by manipulating the state of the broadband switching elements. In addition, the NBPS is based on a Wavelength-Selective-Switching (WSS) for handling all communication configuration tasks.
Second, a new contention-aware path configuration algorithm and architecture for Electro-Assisted Photonic Network-on-Chip (EA-PNoC) is proposed. In addition to the main configuration tasks, the algorithm also decouples the Electronic Control Network (ECN) from the Photonic Communication Network (PCN) in a manner that both photonic and electric domains work independently from each other. The proposed algorithm orchestrates the different path configuration packets processes and significantly alleviates the contention in the ECN.
Third, a low-complexity routing and configuration algorithm for EA-PNoC is proposed. The approach is mainly based on photonic components augmented with a simple electronic control module and a so-called wavelength-shifting mechanism. The main merit of this new approach is to configure the path using photonic devices instead of the typical power-hungry electronic router.
The proposed architectures and algorithms were evaluated with a discrete-event simulator, which incorporates detailed physical models of the photonic components. Results show that we could achieve better energy efficiency, as well as a considerable reduction in the blocking occurrence, which is the main source of latency and bandwidth degradation in conventional EA-PNoCs.

高性能計算システムやより高度な微細化技術への需要の高まりは、単一チップ上により多くのコアを統合するという手法へと向かわせた。次世代の高性能計算用メニーコアシステムにおいて、効率的な通信基盤は、単独のコアの計算効率と同様に重要である。現在 electrical Networks-on-chips (NoCS) は、コア数の増加にともなう電源不足や性能低下の問題へアプローチする手法として期待されている。
ITRSロードマップの最新版が示す通り、フォトニックワイアリングは、既存のメタルによる相互配線と適合しない広帯域データ転送レートを提供する将来的なsystem-on-chip (SoC) 設計への有望なパラダイムである。Wavelength Division Multiplexing (WDM)と組み合わせたとき、複数の並列した光学データストリームは単一の導波管 (waveguide) に同時に転送される。 これは Electronic Networks-on-Chip (ENoCs) がビットストリームごとに別々のメタル配線を要することと、対称的である。
光学スイッチング・ルーティング技術、配置手法、ルーティングアルゴリズムは、将来的なメニーコアのオンチップ上光学通信の性能と消費電力の特性に直接影響する。とりわけ、異なる電子制御機能を編成する、制御モジュールと経路設定アルゴリズムは、電気的なリソースと光学的なリソース両方をどうやって利用するかという点で、重要な役割を担っている。本論文では、将来的なオンチップの光学ネットワークのための、革新的な光学ルーティングアルゴリズムとアーキテクチャのセットを提案している。
第一に、新しい低レイテンシ non-blocking photonic switch/router (NBPS) と、全光学通信の設定タスクを扱える制御モジュールを提案する。この提案手法は、光学データストリーム転送のための新しいハイブリッド空間のスイッチング機構をベースとし、広帯域スイッチングエレメントの状態を操作することで行われる。くわえて、このNBPSは、全ての通信設定タスクを扱う Wavelength-Selective-Switching (WSS) の上に成り立っている
第二に、新しい contention-aware 経路設定アルゴリズムとアーキテクチャを提案する。メインの設定タスクに加えて、このアルゴリズムは、光学的領域と電気的領域でそれぞれ個別に動作するシステムの、the Electronic Control Network (ECN) を Photonic Communication
Network (PCN) から分離させている。本提案手法は、ECN中の競合の処理をし著しく緩和する、異なるパスセットアップパケットを編成する。
第三に、ハイブリッド光学 Network-on-Chip のための低複雑性ルーティングおよび設定アルゴリズムを提案する。この手法は主に、シンプルな電気的制御モジュールといわゆる wavelength shifting 機構によって強化された光学デバイスをベースとしている。
