Foreward

This document was originally written several years ago. At the time I was working as an execution core verification engineer at Arm. The following points are coloured heavily by working in and around the execution cores of various processors. Apply a pinch of salt; points contain varying degrees of opinion.

It is still my opinion that RISC-V could be much better designed; though I will also say that if I was building a 32 or 64-bit CPU today I'd likely implement the architecture to benefit from the existing tooling.

Mostly based upon the RISC-V ISA spec v2.0. Some updates have been made for v2.2

Original Foreword: Some Opinion

The RISC-V ISA has pursued minimalism to a fault. There is a large emphasis on minimizing instruction count, normalizing encoding, etc. This pursuit of minimalism has resulted in false orthogonalities (such as reusing the same instruction for branches, calls and returns) and a requirement for superfluous instructions which impacts code density both in terms of size and

A minimal Forth implementation in C#
/*
* Minimal .NET Forth implementation. Just an experiment. Do not use for anything serious.
* by Tycho Luyben (https://github.com/tluyben)
*
* The only 'primitive' (built-in) is an foreign function interface word which allows you to define
* whatever is needed, for example:
*
* hello System.String System.Console.WriteLine ffi
*
* will print hello.

Simple tool that redirects it's standard input to input buffer of a terminal (i.e. fake input to some terminal)

About

It is possible to redirect some input to TTY device by standard IO redirection.

echo ahoj > /dev/tty1

Such redirection will however end in the output buffer of the TTY device so the characters will be ghosts - visible on the terminal, but not effective. It is, in fact, not possible by standard tools to redirect input to terminal as if it is a real input from keyboard.

Orthodox C++

Orthodox C++

What is Orthodox C++?

Orthodox C++ (sometimes referred as C+) is minimal subset of C++ that improves C, but avoids all unnecessary things from so called Modern C++. It's exactly opposite of what Modern C++ suppose to be.

Why not Modern C++?
