Math in Game Development Summit: Even Faster Math Functions

Robin Green  (Programmer, Pacific Light & Hologram)

Date: Tuesday, July 20

Time: 2:40pm - 3:10pm

Pass Type: All Access Pass, Summits Pass

Topic: Programming

Format: Session

Vault Recording: Video

For experienced programmers we present a deep dive into coding math functions down to the bit level, with an emphasis on FPGA implementations. We will visit the latest research inspired by the latest FPGA solutions, bitheaps, bipartite tables and CORDIC engines. This is the fundamental math on how to math when all you have are bits.


Attendees will learn a toolbox of techniques for coding accurate, efficient implementations of math functions that take the fewest resources and produce correctly rounded results to any number of bits required. The course aims to set up devs with the basic tools for math on FPGA for advanced hardware emulators, soft CPU instructions and homebrew GPU experiments.

Intended Audience

Aimed at embedded programmers working directly with bare metal, and experienced developers wanting to look at familiar algorithms from a different vantage point. Use of binary, hexadecimal, 2s-compliment and fixed-point arithmetic will be presumed.
