Assembly's Perspective of C

If you are living under a rock, quarantined against COVID-19, here’s quite a long, and somewhat technical, post for your consumption. This post will talk about how C and assembly dance together–the tango? waltz? who knows?

One-pass Compiler

A one-pass compiler emits assembly (or binary code) right during parsing, without creating an intermediate representation, such as an AST. This is a rare technique that was used back in the days when computer memory was scarce. This limited both the language features that were possible and the quality of the produced…

Programming with RISC-V Vector Instructions

Perhaps the most interesting part of the open RISC-V instruction set architecture (ISA) is the vector extension (RISC-V "V"). In contrast to the average single-instruction multipe-data (SIMD) instruction set, RISC-V vector instructions are vector length agnostic (VLA). Thus, a RISC-V "V" CPU is flexible in choosing a…

Dolphin Progress May and June 2020

We've got a lot to get through the past two months. Headlining it all is that we're happy to announce support for a new compressed disc format developed specifically for Dolphin: RVZ. This lossless format allows for near top of the line game compression without compromising the integrity of ISOs,…

Better Geometry Through Graph Theory (2018)

A few months ago, I decided to implement set operations on curved regions. I had the the canonical textbook on computational geometry , which described approaches for polygons comprised of straight lines, and it seemed like other projects had extended these techniques to parametric curves . I figured it would take a…

J Notation as a Tool of Thought

Kenneth Iverson’s 1964 language, APL, won him the Turing Award. His award lecture, Notation as a Tool of Thought, argued that better notations would lead people to deeper insights about mathematics. He provided a number of examples ranging across linear algebra, arithmetic, probability, and logic. Unfortunately, most…
