AetherQuist天衢星脉

The heavenly thoroughfare for AI interconnect为智能时代,
铺就天衢

AetherQuist is a systems company for end-to-end communication: the chips, and the channels between them. We connect GPUs, CPUs and switches with electrical and optical I/O, from the chiplet to the rack to the package.

天衢星脉是一家系统公司,专注于端到端的通信芯片与通道。我们以电互联与光互联连接 GPU、CPU 与交换芯片,从芯粒到机柜,再到封装级光互联。

End to end: the chip and the channel端到端:芯片与通道

We are a systems company. A link is only as fast as its weakest part, so we design the whole path a signal travels, from one die to the next, and every channel in between.我们是一家系统公司。一条链路的速度取决于它最薄弱的一环,因此我们设计信号经过的完整路径:从一颗芯片到另一颗芯片,以及其间的每一段通道。

Five disciplines carry a design from first silicon to volume shipments.五项核心能力,让设计从首颗硅片走向规模量产。

High-volume manufacturing大规模量产
Taking chips from first silicon to high-yield production at scale.让芯片从首颗硅片走向高良率的规模化生产。
Power and signal integrity电源与信号完整性
Keeping power clean and signals open across die, package, board and cable.在芯片、封装、电路板与线缆之间,保持电源纯净、信号清晰。
3DIC
Stacking and placing dies side by side in advanced packages.在先进封装中实现芯片的堆叠与并排集成。
DTCO
Design-technology co-optimization: tuning circuits and process together.设计与工艺协同优化,让电路与制程共同调优。
O/E integration光电集成
Bringing optical and electrical I/O together in one package.在同一封装中融合光互联与电互联。

From chiplet to rack to optical package从芯片级到机柜级,再到封装级光互联

Our roadmap moves in three stages. Each stage widens the reach of the thoroughfare: first between dies, then across the rack, then into the package through light.我们的发展分三个阶段演进,每一阶段都让天衢延伸得更远:先在芯粒之间,再跨越整个机柜,最终以光进入封装。

Stage one阶段一MPU/GPU/CPU/Switch IO Chiplets
Stage two阶段二Rack-scale fabric机柜级互联 Fabric
Stage three阶段三Package-level optical bridge封装级光桥
900GB/s
1.8TB/s
3.6TB/s
P1112G PHY
32G D2D
P2224G PHY
64G D2D
P3New package新封装
Rack-scale interconnect fabric机柜级互联 Fabric
Optical bridge integration光桥集成(Scale-In)
Electrical电互联
Optical光互联

Electrical links are narrow and fast; optical links (VCSEL) are wide and slow. Both kinds of I/O die run through all three stages.电互联窄而快;光互联(VCSEL)宽而慢。两类 IO die 贯穿三个阶段。

The road through the heavens天衢之路

Long ago, astronomers looked up at the night sky and saw more than scattered lights. They saw roads. The ancient Chinese called the great celestial avenue 天衢, the heavenly thoroughfare, and they described the currents linking star to star as 星脉, the veins and pulse of the sky. In their eyes, the heavens were not empty. They were a network.

Far to the west, the Greeks gave that upper sky a name of its own: Aether, the bright, pure medium the gods breathed. Centuries later, scientists believed light itself traveled through the aether. When engineers built the first great computer network, they named it Ethernet in its honor.

Then, in the twentieth century, a quiet engineer named Harry Nyquist asked a deceptively simple question: how fast can a signal truly travel through a channel? His answer defined the limits that every high-speed link still pushes against today.

AetherQuist is born where these stories meet.

Aether is the heaven that carries light. Qu is 衢, the thoroughfare where every road meets. Quist honors Nyquist, and the pursuit of speed at the very edge of what physics allows.

Today, the stars we connect are processors: GPUs, switches, and chiplets, each one a point of light in the vast constellations that power artificial intelligence. Between them run our links, carrying billions of pulses every second, a modern 星脉 beating through silicon.

We build the heavenly thoroughfare for the age of intelligence. Where every signal finds its way.

《诗经·大雅·云汉》有云:"倬彼云汉,昭回于天。"1

古人仰望星空,看见的不是零落的光点,而是道路。那条横贯苍穹的大道,名曰"天衢";连接群星、流转不息的脉络,谓之"星脉"。在先民眼中,天空从不空寂,它本就是一张网。

《尔雅》曰:"四达谓之衢。"2 衢,是四通八达、万路交汇之所。

在遥远的西方,古希腊人把高远澄明的上天称为 Aether,那是众神呼吸的纯净之气。后世的科学家相信,光正是穿行于这"以太"3之中;人类第一张伟大的计算机网络,也因此得名"以太网"。

二十世纪,工程师奈奎斯特4提出了一个看似简单的问题:信号在信道中究竟能跑多快?他的答案,划定了至今所有高速链路不断挑战的极限。

AetherQuist 天衢星脉,诞生于这些故事的交汇之处。

Aether,是承载光的天穹;Qu,是衢,万路交汇的通衢;Quist,致敬奈奎斯特,致敬在物理极限边缘对速度的不懈追求。

《周易·大畜》云:"何天之衢,亨。"5 行于天上的通衢,畅达无阻。这正是我们心中的信号之路:四方通达,畅行无碍。

今天,我们所连接的"星辰"是处理器:GPU、交换芯片与芯粒,每一颗都是智能星图中的一点光芒。它们之间奔流着我们的链路,每秒承载亿万次脉冲,那是跳动于硅片之中的当代星脉。

为智能时代,铺就天衢。让每一个信号,都找到它的路。

  1. 出自《诗经·大雅·云汉》。"倬"意为明亮显著,"云汉"即银河,"昭回"指光辉回转。全句意为:那明亮的银河,在天空中闪耀流转。
  2. 出自《尔雅·释宫》。古人按道路通达的方向为其命名,"四达"即通往四方,"衢"因此指四通八达的大道。
  3. "以太"是希腊语 Aether 的中文译名。古希腊人以它指称天界的纯净之气;十九世纪物理学家曾假设它是光传播的介质。以太网(Ethernet)即由此得名。
  4. 哈里·奈奎斯特(Harry Nyquist, 1889–1976),美国贝尔实验室工程师,现代通信理论的奠基人之一。他提出的采样定理与"奈奎斯特频率",至今仍是高速信号传输的基础。
  5. 出自《周易·大畜》上九爻辞。"何"通"荷",意为承载,一说为赞叹之词;"衢"为四通八达的大路;"亨"即亨通。《象传》释曰:"何天之衢,道大行也",意为大道通行、畅达无阻。"天衢"一词即出于此。

Three sources, one name三条源流,汇成一个名字

Aether 以太

Heaven, from Greek天,源自希腊

The Greek upper sky, later imagined as the medium light travels through. Ethernet is named after it.

古希腊人眼中澄明的上天,也曾被认为是光的传播介质。以太网由此得名。

Qu 衢

Thoroughfare, from Chinese衢,源自中国

"A road open in four directions is called qu." The meeting place of every route, taken from 天衢, the heavenly thoroughfare.

《尔雅》:四达谓之衢。万路交汇、四通八达的通衢大道,取自"天衢"。

Quist 奈奎斯特

Speed, from science速度,源自科学

Harry Nyquist of Bell Labs answered how fast a signal can travel through a channel, the limit every high-speed link pushes against.

贝尔实验室工程师奈奎斯特,回答了"信号能跑多快",划定了高速链路的极限。
