Research direction

Start by reading the vector APIs and reduction patterns in the repository, then check how its supported x86 vector instructions handle multiply-and-accumulate at higher precision. Define a std::inner_product-like operation that supports those instructions; done means the API and its behavior are specified and it can use the relevant hardware operations. The issue does not name files or tests, so locating the entry point will take repository exploration.

Written by the indexing model from the issue text.

Description

Provide a std::inner_product-like function, which is useful for signal processing. Note that many instructions exist in x86 to help implement this (e.g., madd, VNNI), which often allow the accumulation at higher-precision. Specifying the function in a way which allows them to be used is very important.
