Sub-system
An automated driving computer runs several neural networks on multiple sensor streams, every frame, with a hard deadline — inside a sealed box with no fan, over a fifteen-year life, in temperatures from freezing to baking. The constraints are what make it difficult, not the arithmetic.
In one sentence
Autonomy compute is the in-vehicle computing platform that runs perception, prediction and planning models on sensor data in real time, under automotive power, thermal, reliability and functional-safety constraints.
The workload resembles data-centre inference in kind and differs in every constraint. It cannot be batched, because there is one vehicle and one moment. It has a hard deadline: an answer after the deadline is a failure, not a slow success. And the power budget is tens to low hundreds of watts, dissipated without a fan in a sealed enclosure.
On top of that sits the safety requirement. A system trusted with control must detect its own faults and reach a safe state when it cannot function — which typically means redundant computing paths and continuous self-checking rather than a single fast processor.
The metric is end-to-end time from photon to actuator, including sensor capture, transfer, inference, fusion, planning and control. The worst case matters, not the average: a system that is fast almost always and occasionally slow is unsafe, so the platform is specified for guaranteed timing rather than peak performance.
Silicon must be qualified for automotive temperature ranges and reliability targets over a decade and a half, which restricts process choices and adds years to a chip programme. Cooling is passive and the power budget is constrained by the vehicle's electrical system. These are the reasons an in-vehicle computer trails data-centre hardware by generations.
Functional safety requires that a failure be detected and handled. That means duplicated computing paths, cross-checking between them, and a defined degraded behaviour — hand back to the driver, or bring the vehicle to a controlled stop. Designing what happens when the computer fails is as much of the work as making it fast.
Technology dependencies are solved by engineering; supply dependencies are solved by building something, which takes years.
Purpose-designed silicon qualified for automotive temperature, lifetime and safety requirements.
Foundry vs IDMNetworks are quantised and compiled for the specific accelerator; the same techniques as data-centre serving, under tighter constraints.
QuantisationArchitecture, redundancy and diagnostic coverage are dictated by safety standards, not chosen freely.

What each company supplies at this step, and — where a public figure exists — its share of this specific market — with what that share measures, the period it covers and who published it. Some rows also show the company’s own reported revenue for the segment covering this step, which is a different thing: it says how much this business matters to that company, not how much of the market it holds. Not a ranking and not a recommendation.

Each page explains one technology in plain language, states what it depends on, and names companies by what they supply at that step. Company roles are described qualitatively and deliberately carry no market shares, revenue figures or rankings — those change faster than an explainer can, and a stale number is worse than none. Ticker links point at company pages on this site and are provided for reference only.
Nothing here is investment advice, a recommendation, or a forecast. A company named on a page about a technology is not thereby a good investment, and the chokepoints described are structural facts about supply chains rather than predictions about prices. Technology moves; where a page describes something as unresolved or in development, that was true when it was written.
