Software Design Pattern that allows for developers to add functionality to a larger system without having to alter the source code of the system itself. Plug-ins are self-contained

The book also contains many insights about computer architecture in general, as well as explaining the particular de- sign choices we made in creating RISC-V. the point, and complete. The book’s commentaries provide a gratuitous history, motivation, and architecture critique. —C. Gordon Bell, Microsoft and designer of the Digital PDP-11 and VAX-11 instruction handy little book effortlessly summarizes all the essential elements of the RISC-V Instruction Set Architecture, a perfect reference guide for students and practitioners alike. —Professor Randy Katz, University

embedded software • Started using C++ in 1995 • First cross-platform project in 1994Cross-Platform Architecture Goals • Take advantage of all platforms • Focus on the compiler • Minimize boilerplate and unnecessary requiring implementations that differ depending upon the target machine architecture. • Features may be hardware: CPU architecture, SIMD instruction set, DMA controller, GPIO module, etc. • Features

2 Decentralized package manager Conan is a decentralized package manager with a client-server architecture. This means that clients can fetch packages from, as well as upload packages to, different servers and compiler version, or the computer architecture. If the package is built again from the same sources but with different settings, (e.g. for a different architecture), a new, different binary will be generated is saved. Note: Conan generates a default profile with your detected settings (OS, compiler, architecture...) and that configu- ration is printed at the top of every conan install command. However, it
