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

Eagle-200 Local Usage via CURL

You can locally pull data from your Rainforest Eagle-200 using cURL.

Rainforest has published a local API document which explains the details of the protocol. But this particular document is about quickly getting to the point and giving you some cURL commands you can use to immediately start pulling out data.

Prerequisites

First, I'll assume that you have the following environment variables set:

#!/usr/bin/env bash
# --slave /usr/bin/$1 $1 /usr/bin/$1-\${version} \\
function register_clang_version {
local version=$1
local priority=$2
update-alternatives \
--install /usr/bin/llvm-config llvm-config /usr/bin/llvm-config-${version} ${priority} \
