How PCIe Interconnect is Critical for the Emerging AI Era
By Annie Liao, Product Management Director, Connectivity, Marvell
PCIe has historically been used as protocol for communication between CPU and computer subsystems. It has gradually increased speed since its debut in 2003 (PCI Express) and after 20 years of PCIe development, we are currently at PCIe Gen 5 with I/O bandwidth of 32Gbps per lane. There are many factors driving the PCIe speed increase. The most prominent ones are artificial intelligence (AI) and machine learning (ML). In order for CPU and AI Accelerators/GPUs to effectively work with each other for larger training models, the communication bandwidth of the PCIe-based interconnects between them needs to scale to keep up with the exponentially increasing size of parameters and data sets used in AI models. As the number of PCIe lanes supported increases with each generation, the physical constraints of the package beachfront and PCB routing put a limit to the maximum number of lanes in a system. This leaves I/O speed increase as the only way to push more data transactions per second. The compute interconnect bandwidth demand fueled by AI and ML is driving a faster transition to the next generation of PCIe, which is PCIe Gen 6.
PCIe has been using 2-level Non-Return-to-Zero (NRZ) modulation since its inception. Increasing PCIe speed up to Gen 5 has been achieved through doubling of the I/O speed. For Gen 6, PCI-SIG decided to adopt Pulse-Amplitude Modulation 4 (PAM4), which carries 4-level signal encoding 2 bits of data (00, 01, 10, 11). The reduced margin resulting from the transition of 2-level signaling to 4-level signaling has also necessitated the use of Forward Error Correction (FEC) protection, a first for PCIe links. With the adoptions of PAM4 signaling and FEC, Gen 6 marks an inflection point for PCIe both from signaling and protocol layer perspectives.
In addition to AI/ML, disaggregation of memory and storage is an emerging trend in compute applications that has a significant impact in the applications of PCIe based interconnect. PCIe has historically been adopted on-board and for in-chassis interconnects. Attaching more front-facing NVMe SSDs is one of the common PCIe interconnect examples. With the increasing trends toward flexible resource allocation, and the advancement of CXL technology, the server industry is now moving toward disaggregated and composable infrastructure. In this disaggregated architecture, the PCIe end points are located at different chassis away from the PCIe root complex, requiring the PCIe link to travel out of the system chassis. This is typically achieved through direct attach cables (DAC) that can range up to 3-5m.

AI時代のマーベルの光学技術とイノベーションに光を当てる
By Kristin Hehir, Senior Manager, PR and Marketing, Marvell
The sheer volume of data traffic moving across networks daily is mind-boggling almost any way you look at it. During the past decade, global internet traffic grew by approximately 20x, according to the International Energy Agency. One contributing factor to this growth is the popularity of mobile devices and applications: Smartphone users spend an average of 5 hours a day, or nearly 1/3 of their time awake, on their devices, up from three hours just a few years ago. The result is incredible amounts of data in the cloud that need to be processed and moved. Around 70% of data traffic is east-west traffic, or the data traffic inside data centers. Generative AI, and the exponential growth in the size of data sets needed to feed AI, will invariably continue to push the curb upward.
Yet, for more than a decade, total power consumption has stayed relatively flat thanks to innovations in storage, processing, networking and optical technology for data infrastructure. The debut of PAM4 digital signal processors (DSPs) for accelerating traffic inside data centers and coherent DSPs for pluggable modules have played a large, but often quiet, role in paving the way for growth while reducing cost and power per bit.

AIとデータインフラに訪れる地殻変動
By Michael Kanellos, Head of Influencer Relations, Marvell
AI’s growth is unprecedented from any angle you look at it. The size of large training models is growing 10x per year. ChatGPT’s 173 million plus users are turning to the website an estimated 60 million times a day (compared to zero the year before.). And daily, people are coming up with new applications and use cases.
As a result, cloud service providers and others will have to transform their infrastructures in similarly dramatic ways to keep up, says Chris Koopmans, Chief Operations Officer at Marvell in conversation with Futurum’s Daniel Newman during the Six Five Summit on June 8, 2023.
“We are at the beginning of at least a decade-long trend and a tectonic shift in how data centers are architected and how data centers are built,” he said.
The transformation is already underway. AI training, and a growing percentage of cloud-based inference, has already shifted from running on two-socket servers based around general processors to systems containing eight more GPUs or TPUs optimized to solve a smaller set of problems more quickly and efficiently.

HPEにおけるMarvellイーサネット・アダプタの製品名変更について
By Todd Owens, Field Marketing Director, Marvell
Hewlett Packard Enterprise (HPE) recently updated its product naming protocol for the Ethernet adapters in its HPE ProLiant and HPE Apollo servers. Its new approach is to include the ASIC model vendor’s name in the HPE adapter’s product name. This commonsense approach eliminates the need for model number decoder rings on the part of Channel Partners and the HPE Field team and provides everyone with more visibility and clarity. This change also aligns more with the approach HPE has been taking with their “Open” adapters on HPE ProLiant Gen10 Plus servers. All of this is good news for everyone in the server sales ecosystem, including the end user. The products’ core SKU numbers remain the same, too, which is also good.

強化されたワイヤレス マイクロコントローラでは手頃な設計が可能に
By Sree Durbha
Today, we are at the peak of technology product availability with the releases of the new iPhone models, Alexa enabled devices and more. In the coming days, there will be numerous international consumer OEMs preparing new offerings as we approach the holiday selling season. Along with the smartphones, voice assistant enabled smart speakers and deep learning wireless security cameras, many devices and appliances are increasingly geared toward automating the home, the office and the factory. These devices are powered by application microcontroller units (MCUs) with embedded wireless connectivity to help users to remotely control and operate them via phone apps, voice or even through mere presence. This is part of an industry trend of pushing intelligence into everyday things. According to analyst firm Techno Systems Research1, this chipset market grew by more than 60% over the course of the last year and is likely to continue this high rate of growth. The democratization of wireless connectivity intellectual property and the continuing shift of semiconductor design and development to low cost regions is helping give rise to new industry players. In order to help customers differentiate in this highly competitive market, Marvell has announced the 88MW320/322 low-power Wi-Fi microcontroller SoC. This chipset is 100% pin-compatible and software compatible with the existing 88MW300/302 based designs. Although the newly released microcontroller is cost-optimized, there are several key hardware and software enhancements in this chipset. Support for extended industrial temperature operation, from -400 C through to 1050 C has been added. Unlike its predecessor, the 88MW320/322 can be implemented into more challenging application areas - such as LED lighting and industrial automation. No RF specific changes have been made within the silicon, so the minimum and maximum RF performance parameters remain the same as before. However, other fixes made have helped improve typical RF performance as reported by some of our customers when evaluating samples. Since there was no change in form, fit or function, the external RF interface remains the same as well. This enables customers to leverage existing 88MW300/302 module and device level regulatory certification on 88MW320/322. A hardware security feature has also been incorporated that allows customers to uniquely tie the chipset to the firmware running on it. This helps prevent counterfeit software to run on the chipset. This chipset is supported by the industry-leading Marvell EZ-Connect SDK for Apple’s new Advanced Development Kit (ADK) and Release 13 HomeKit Accessory Protocol SDK (R13 HAPSDK) with software-based authentication (SoftAuth), Amazon’s AWS IoT and other third-party cloud platforms. The Apple SoftAuth support now allows customers to avoid the cost and hassle of adding the MFi authentication chip, which was previously required to get HomeKit certification. On the applications side, we have added support for the Alexa Voice Services library. With MP3 decoder and OAUTH2 modules integrated on our SDK, our solution now allows customers to add an external audio-codec chipset to offer native voice command translation for basic product control functions. As previously announced, we continue to partner with Dialog Semiconductor to offer support for BLE with shared antenna managed coexistence software with our Wi-Fi on 88MW320/322. Several of our module vendor partners have announced support for this chipset in standalone and Wi-Fi + BLE combo configurations. You can find a complete list of modules supporting this chipset on the Marvell Wireless Microcontrollers page. The 88MW320/322 has been sampling to customers for a few months now and is currently shipping. The product comes in 68-pin QFN package (88MW320) and 88-pin QFN package (88MW322) formats. It is available in commercial, extended, industrial and extended industrial temperature ranges in both tray and tape and reel configurations. Watch this space for future announcements as we extend the availability of Marvell’s solutions for the smart home, office and factory to our customers through our catalog partners. The goal is to enable our wireless microcontroller solutions with easy to install one-click software that allows smaller customers to use our partner reference designs to develop their form factor proof of concept designs with hardware, firmware, middleware, cloud connectivity software, collateral and application support from a single source. This will free up their resources so that they can focus on what is most important to them - which is to work on application software and differentiation. The best is yet to come. As the industry demands solutions with higher levels of integration at ever lower power to allow for wireless products with several months and even years of battery life, you can count on Marvell to innovate to help meet customer needs. For example, the 802.11ax standard specification is not just for high efficiency and high throughput designs, it also offers provisions for low power, long battery life designs. 20MHz only channel operation in the 5GHz band and features such as target wake time (TWT), which helps extend the sleep cycle of devices; dual sub-carrier modulation (DCM), which helps extend the wireless range; uplink and downlink OFDMA, all contribute to make the next generation of devices worth waiting for.

なぜ 802.11ax がコネクテッドカーに「必須」なのでしょうか？
アビナッシュ・ギルニカー著
運転しながら学習し、より賢く、より安全で、より信頼できるようになる新しいコネクテッドカーで、混雑した都会の交通を走り抜けることを想像してみてほしい。 このような車両は常にあらゆるデータを収集し、生成しており、それらは断続的かつ臨機応変にクラウドにアップロードされる。 より多くの自動車が高度なワイヤレス接続機能を搭載するようになれば、このエキサイティングな未来は当たり前のものになるだろう。 しかし、各車両は、その周辺にいる可能性のある何百台もの他の車両とネットワークを共有する必要がある。 このようなユースケースはLTE/5Gセルラー技術に依存する可能性があるが、そのような「ライセンスパイプ」を採用することに関連するコストは法外に高くつくだろう。 このような状況において、新しいWi-Fi®規格802.11axは、highefficiencywireless（HEW）としても知られ、自動車業界にとって救世主となる。 今後数年間で、多数のセンサーを搭載した自動車が生み出すゼタバイト級のデータは、すべてクラウドやデータセンターにアップロードされる必要があり、将来的に運転をより安全で予測可能なものにするために、次世代の機械学習を可能にする。 このデータのアップロードは、もちろん安全かつ確実に行われる必要がある。
また、802.11axステーション（STA）として、他のクライアントとネットワークを共有しながら、最も困難な無線環境で802.11axアクセスポイント（AP）にデータをアップロードすることができる。 802.11ax システムは、この新たな規格の一部である新しいイノベーションである MU-MIMO や OFDMA (空間、周波数、時間の再利用を可能にする) などのテクノロジーを通じてこれを行うことができる。 今日、STAはネットワークを効果的に共有するどころか競争し、接続を待つ恐ろしい「死の輪」に対処しなければならない。 これは、今日の無線規格は、絶え間ない競争により、多くの場合、二律背反的な運用になる可能性があることが多いからだ。 802.11ai、特に高速初期リンクセットアップ（FILS）のような他の今後の標準と組み合わせると、車が移動してAPからAPへとホッピングするような環境であっても、Wi-Fi経由でクラウドにデータをアップロードするというこのビジョンは、真の現実になる。
この「ボンネット内」アップロードのユースケースは、インフラの観点から802.11ax標準によって大幅に強化されるが、コネクテッドカーへのソフトウェアとファームウェアのダウンロードも、この同じ標準によって変革することができる。 自動車に搭載されるプロセッサーや電子制御ユニット（ECU）の数が飛躍的に増加することはよく知られている。 このことは、これらの自動車に搭載されるソフトウェア／ファームウェアの内容も同様に、指数関数的な速度で成長することを意味する。 定期的なFOTA（Firmware over-the-air）のアップデートが必要となるため、これをサポートする信頼性の高い堅牢なメカニズムを持つことは、自動車メーカーにとって不可欠となる。これにより、サービスコストなどに関連して数百万ドル経費を節約できる可能性がある。 最近の技術革新と技術変化のペースは非常に速く、自動車が組立ラインから出された直後にこのようなことが起こることもある。
例えば、自動車工場の駐車場には何百台もの新車が停まっており、ソフトウェアのアップデートが必要である。 ここでも、802.11axは大量アップデートをより効率的で信頼性の高いものにすることで、救いの手を差し伸べることができる。 これらの車がどのような無線接続環境に遭遇するかは決して予測できないため、この利点は各車の残りの寿命にわたって引き継がれる。 車庫や私道、あるいは駐車場デッキのような困難な環境である可能性もある。 802.11axが提供する変調機能の強化は、MU-MIMOおよびOFDMA機能と相まって、このような重要な機能に対して最も効率的で信頼性の高いWi-Fiパイプが常に利用できることを保証する。 車両が10年近くも走り続けることを考えれば、この機能が初日から組み込まれていることは非常に大きな利点であり、大幅なコスト削減を可能にする。 Wake on Bluetooth® Low EnergyやBluetooth Low Energy Long Rangeのような付随技術もまた、全体的なエンドツーエンドシステムの観点から、このユースケースを確実に実現する上で極めて重要な役割を果たすだろう。
これら2つのインフラタイプのユースケースは、コネクテッドカーにとって非常に大きな付加価値となる可能性が高く、特に自動車メーカーの観点から802.11axの存在を正当化することができる。 インフォテインメントシステムのモバイルAPが最新のスマートフォン端末（2019年中に802.11axに対応する予定）とシームレスに接続できるようになるため、消費者も自動車のダッシュボードで大きなメリットを実感できるだろう。 ワイヤレスApple CarPlay®、ワイヤレスAndroid Auto™プロジェクション、後部座席エンターテイメント、ワイヤレスカメラなどのユースケースは、802.11axの30～40%のスループット向上（そして、このようなユースケースが協調して共存できるように、この規格が従来のWi-Fi規格との下位互換性を持っている）により、すべて簡単になります。 住宅内と同じように、車内のWi-Fiエンドポイントの数も増加している。 802.11ax規格は、増加するエンドポイントに対応し、かつ最高のユーザーエクスペリエンスを提供する、唯一うまく設計されたパスである。
リリース1（別名Wave 1）としての802.11axは、2019年後半のWi-Fiアライアンスによる具体的な発表に向けて順調に進んでいる。 製品は、AP側とSTA/モバイルAP側の両方で、シリコンベンダーによってすでにサンプル出荷されており、相互運用性テストも順調に進んでいる。 OEMとそのTier 1サプライヤーの無線システム設計者全員にとって、802.11ax Wi-Fi規格は目標であるべきで、特に2020年以降に発売される製品にとってはそうであるべきだ。 間近に迫った802.11axインフラの到来に備え、未来への備えを始める時が来た。 スマートフォン／住宅内／企業内と車内のワイヤレス技術が異なる世代に属していた時代はすでに終わっている。 消費者は今、クルマが住宅／職場環境の延長であり、これらすべての生活空間が一体として機能することを求めている。 802.11axは、そのようなビジョンを現実のものとする技術の重要な柱のひとつとなる運命にある。
マーベルは、2011年に車載用Wi-Fi/Bluetoothコンボデバイスを発表して以来、車載用Wi-Fi/Bluetoothコンボデバイスのパイオニアである。 約10年前に開発が開始されたマーベルの車載用ワイヤレス製品群は、OEM、ティア1、ティア2と密接に協力することで、5世代にわたる製品の主要なユースケースに対応できるよう磨きをかけてきた。 上記のようなさまざまなユースケースを実現するために必要な技術はすべて、マーベルの第5世代デバイスに組み込まれている。 エンタープライズ・クラスの高性能APを提供するマーベルと組み合わせることで、マーベルは自動車業界と自動車購入者に現在および将来の自動車の内外のユースケースを網羅する最高のワイヤレス接続体験を引き続き提供することを約束する。
