SUMMARY: AO real-time control using open source and COTS components 
DESCRIPTION: AO real-time control using open source and COTS components \nD
 r. Alastair Basden\n\nAdaptive optics systems rely on a real-time control 
 system which is  responsible for receiving wavefront sensor information an
 d computing and  applying the necessary correction to the deformable mirro
 rs.  Historically, real-time control systems have relied on customised  ha
 rdware comprised of multiple FPGA and DSP systems, which high  complexity.
   More recently it has been demonstrated that conventional  PCs are now su
 fficiently powerful to to perform this task.  In this  talk, I will presen
 t an open-source real-time control system, DARC,  discuss its implementati
 on on the CANARY AO system at the William  Herschel Telescope, and cover t
 he algorithms available.  Extension to  ELT-scale operation will be discus
 sed, including hardware and detector  considerations.  The internal archit
 ecture of this modular system will  be presented, with a case being made f
 or its suitability for  implementation on any AO system type, on any teles
 cope.
