DESCRIPTION:Have you ever wondered how the chips and algorithms that made 
 all those electronic music hits work? Us too! At The Usual Suspects we cre
 ate open source emulations of famous music hardware\, synthesizers and eff
 ect units. After releasing some emulations of devices around the Motorola 
 563xx DSP chip\, we made further steps into reverse engineering custom sil
 icon chips to achieve what no one has done before: a real low-level emulat
 ion of the JP-8000. This famous synthesizer featured a special "SuperSaw" 
 oscillator algorithm\, which defined an entire generation of electronic an
 d trance music. The main obstacle was emulating the 4 custom DSP chips the
  device used\, which ran software written with a completely undocumented i
 nstruction set. In this talk I will go through the story of how we overcam
 e that obstacle\, using a mixture of automated silicon reverse engineering
 \, probing the chip with an Arduino\, statistical analysis of the opcodes 
 and fuzzing. Finally\, I will talk about how we made the emulator run in r
 eal-time using JIT\, and what we found by looking at the SuperSaw code.
