Quantum Effect Dev

Quantum Effect Devices (QED, originally Quantum Effect Design) was a fabless semiconductor company founded in 1991 by former MIPS Computer Systems managers Tom Riordan, Earl Killian, and Ray Kunita. QED designed MIPS-based 32- and 64-bit embedded RISC microprocessors (the RM5200 and RM7000 families) for networking and communications systems including routers, switches, and optical transport equipment. The company completed an IPO in 2000 and was acquired the same year by PMC-Sierra for approximately $2.3 billion. It has no independent operations, developer platform, or API surface today; the former corporate site (qedinc.com) is defunct. This record was surfaced as a Lightspeed Venture Partners portfolio company and is retained as a historical/no-API-surface entry.

Quantum Effect Dev is profiled on the APIs.io network. Tagged areas include Company, Semiconductors, Microprocessors, MIPS, and Networking.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/quantum-effect-dev: open an issue to ask a question, or submit a pull request to add artifacts.
