libgemmlowp-dev - 0.0~git20211220.e844ffd-1 main

This is not a full linear algebra library, only a GEMM library: it only does
general matrix multiplication ("GEMM").
.
Its performance goals differ from typical GEMM performance goals in the
following ways:
1. It cares not only about speed, but also about minimizing power usage.
It specifically cares about charge usage in mobile/embedded devices.
2. Most GEMMs are optimized primarily for large dense matrix sizes (>= 1000).
It does care about large sizes, but it also cares specifically about the
typically smaller matrix sizes encountered in various mobile applications.
.
Keep in mind (previous section) that gemmlowp itself is a pure-headers-only
library.
