HDSi

HDSi is an acronym that does not designate a single widely recognized topic. In different disciplines, HDSi may be used informally to abbreviate distinct terms or may reflect typographical variations of related terms. Without additional context, the meaning of HDSi remains ambiguous.

In electronics and materials science, some sources use HDSi to refer to silicon with a high dopant density or to specialized silicon substrates used in research and device fabrication. The exact definition is not standardized and the term is not widely adopted as a formal material class in peer‑reviewed literature; readers should consult the accompanying documentation to ascertain the intended meaning.

In broadcasting and video technology, readers may encounter HD-SDI, the High-Definition Serial Digital Interface, a standard for transmitting uncompressed digital video over coaxial cables. HDSi is not the conventional designation for this standard, and its use may reflect a typographical error or shorthand in non-technical materials.

In corporate naming, HDSi can occasionally appear as a misreading or abbreviation of HiSilicon, Huawei's semiconductor design subsidiary. HiSilicon is the organization responsible for some of Huawei's integrated circuits and system-on-chip designs.

In other cases, HDSi may appear as a product code, dataset label, or internal acronym within a specific company or project. In such cases, the precise meaning is defined by the issuing organization.
