Introduction
In this tutorial we learn how to install libgemmlowp-dev on Ubuntu 22.04.
What is libgemmlowp-dev
libgemmlowp-dev is:
This is not a full linear algebra library, only a GEMM library: it only does
general matrix multiplication (“GEMMâ€).
Its performance goals differ from typical GEMM performance goals in the
following ways:
- It cares not only about speed, but also about minimizing power usage.
It specifically cares about charge usage in mobile/embedded devices. - 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.
