Back To Asynchronous Logic
The 21st UK Asynchronous Forum

The University of Bristol,     14th-15th September 2009

The UK Asynchronous Forum is an informal 1-day meeting where those working in asynchronous and related design in the UK (and particularly research students) can meet to present and discuss ideas.  The event is optimised for UK participants though others are welcome to attend.  See the UK Asynchronous Forum home page for further details.

The scope of the Async Forum will be interpreted broadly to include:
  • clockless and multi-clocked systems
  • novel architectures with asynchronous dynamics
  • synchronization and metastability
  • communication-centric design for SoCs, NoCs
  • all sorts of timing issues in system and circuit design
  • variability analysis and variability-tolerance
  • modelling and simulation of NoCs and GALS systems
  • motivating case studies, comparisons, and applications
  • formal methods for correctness, and performance/power analysis
  • test, reliability, security, and radiation tolerance
  • embedded system design with asynchronous architectures/implementations
and anything else relevant of interest.

  • 10th August, 2009              - submission deadline
  • 17th August, 2009              - registration deadline

Extended abstracts of not more than 4 pages must be submitted to Alex Yakovlev (alex.yakovlev at by 10th August.
Abstracts must be sent in either ASCII, postscript (which must be viewable with ghostview) or pdf.

The forum will be held in Room 1.11a in theDepartment of Computer Science , Merchant Venturers Building, at the University of Bristol. For information on how to get there, see this page (we are building 25 on the precinct plan).

The entrance to the Computer Science Department is on the third floor, on Woodland Road, up the (external) steps between Queens' Road and Woodland Road (look for the steps to the right of the tall Wills Memorial Tower and garden).
Accommodation will be in Hiatt Baker Hall, 40 minutes walk from the Department, but easily accessible by public transport. Directions and university accommodation map).

Here is a Google Map of all the Forum's key locations in Bristol.

Bristol is a major transportation hub, and is very well served by:
  • Road (via M4&M5).

  • Air (from Newcastle, Edinburgh, Manchester...) to Bristol International, which has an express shuttle bus service stopping at the university, and also close to the forum accommodation (number 330).

  • Rail (direct to almost every major city in the UK). Rail travellers are advised to travel to Bristol Temple Meads station (not Bristol Parkway), from where the university is about 25 minutes walk (walking directions) (or take one of the frequent buses 8&9 from the station entrance to the "Top of Park Street" [see Google Map], and disembark opposite the iconic Wills Memorial Building Tower [picture]) [other directions and maps]. For the accommodation at Hiatt Baker Hall, Clifton Down station is closer, but with a less frequent, connecting train service.

  • Bristol also has a busy coach station within 10 minutes' walk of the forum venue (map), which offers National Express services every half-hour to London and elsewhere.



Registration costs have been kept as low as possible, in keeping with our desire to make the forum accessible to a broad a range of people. Registration is £65 including accommodation, proceedings and the forum dinner. For people not requiring accommodation, registration is £35.

The absolute deadline for registration is the 17th August 2009. All applications must be received by that date. If you are paying by cheque, remember that your application will need to be sent a few days before this date, to arrive in time through the post.

  Payment: payment can be made either:

  • By cheque, made out to "University of Bristol". Please write "Re: UK Async Forum, COSC/GC1071", and the names of the people you are registering on the back of the cheque, and send it with your registration form (.pdf , .doc) to Kathy Johnston, Department of Computer Science, Merchant Venturers Building, Woodland Road, Bristol, BS8 1UB.

  • By credit/debit card, please fill in the registration form (.pdf , .doc), along with a credit/debit card payment slip (.pdf , .doc), and fax along with the registration form to Kathy Johnston, at the number displayed at the bottom of the sheet.

  • For ALL REGISTRATIONS, as well as processing the payment, as above, please also email a copy of the completed registration form (.pdf , .doc), or a text-list of attendees and accommodation requirements, to simon AT with the subject "Async Forum Registration".
