Speed (overclocking, souped-up BBC Micro, compiler optimisation) – London 28/11/2014

OSHUGThe Open Source Hardware Group will be holding a meeting dedicated to the quest for computing speed. It will feature talks on a hardware design to aid overclocking, retrofitting a 30+ year old microcomputer with modern processors, and compiler optimisation.

The even will take place on the 28th November 201318:00 – 20:00 at Erlang Solutions, New Loom House, 101 Back Church Lane, London, E1 1LU, UK [map] (51.512889-0.067243)

Fast and Furious: Overclocking chips for fun and profit

Due to the variance in silicon manufacturing technologies, integrated circuits used in everyday designs are usually spec’ed at lower speeds than their actual capabilities. It is, therefore, not unlikely for chips to run faster than their advertised speeds, sometimes at significant margins with a little push. The umbrella term used for this practice is overclocking and it encapsulates a variety of techniques from simply increasing the clock speed to employing elaborate systems with liquid nitrogen cooling.

This talk will provide an overview of overclocking and overvolting techniques — investigating the effects of forcing chips to run faster on the silicon level — and present vftweak: an open source hardware design that aims to simplify experimenting with circuits by providing a programmable interface and monitoring tools.

Omer Kilic works on Erlang Embedded, a Knowledge Transfer Partnership project in collaboration with University of Kent and Erlang Solutions. The aim of this project is to bring the benefits of concurrent systems development using Erlang to the field of embedded systems; through investigation, analysis, software development and evaluation.

Before joining Erlang Solutions, Omer was a research student in the Embedded Systems Lab at the University of Kent, working on a reconfigurable heterogeneous computing framework.

Omer likes tiny computers, things that ‘just work’ and real beer.

Souping up the BBC Micro

This talk will introduce a selection of projects which allow modern processors to be used with a 30+ year old BBC Micro, before exploring in more detail the speaker’s own open hardware contribution to the options available.
