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

Access to Ameritrade API

notes that may be helpful for node.js devs

What I've gathered is authorization tokens must be earned first. Authorization tokens are good for three months, once you are setup, you will get two tokens which come as long strings, An access_token and a refresh_token. Access tokens are only valid for 30 minutes so you will need to code to refresh the session using the refresh token frequently. When you refresh, you are given a new access token and that is what you use to "login" or pull from the api for the next period. But in order to get the tokens, you will be required to go through some processes to get a valid token that applies to your app. The following text kind of steers you in that direction...

Making an app

On the api site you will need to make an app, where you pick some random name by using some random numbers. It should be automatically generated but it isnt. For this field item, I simply went to https://www.uuidgenerator.net/ and just grabbed the firs

High-Performance Matrix Multiplication

This is a short post that explains how to write a high-performance matrix multiplication program on modern processors. In this tutorial I will use a single core of the Skylake-client CPU with AVX2, but the principles in this post also apply to other processors with different instruction sets (such as AVX512).

Intro

Matrix multiplication is a mathematical operation that defines the product of
