CASPER Taiwan Workshop 2011

From Casper

Jump to: navigation, search

This three-day course will be held at ASIAA - Taipei, Taiwan on March 23th to 25th 2011. If you would like to participate, please contact

This course is likely to include:

  • Introductory presentations and tutorials to get new users started with CASPER.
  • Hands-on tutorials
  • Advanced uses and digging into the CASPER toolflow.
  • Get all your "How would I... " or "Why does it... " questions answered.
  • Presentations from existing CASPER hardware users.
  • Reports on first ROACH2 .
  • Discuss about the broadband interferometric correlator by CASPER technology.


Before You Attend

If you are unfamiliar with the CASPER tools, you might want to visit Getting Started with CASPER to get a feel for the CASPER design philosophy and how it might help you to meet your science goals.

If you are interested in learning how CASPER hardware and tools might be suitable for a specific instrumentation project, please feel free to prepare details of what you're aiming for. We are eager to spend time discussing potential projects with participants -- this will probably be far more valuable than the structured parts of the workshop.

Visitor Information

The workshop will be held in ASIAA. Please visit ASIAA's website for more details. ASIAA website

The talks will be in Room 1203 and the hands-on labs will be in Room 1301.


The following is a draft program. Suggestions are welcome.

Computing Requirements

Participants will need to bring a laptop computer, preferably with an external mouse to aid working with XILINX/Simulink design tools. Participants will also need to ensure they have a remote desktop protocol (RDP) client installed on their system, as this will be used to access the build systems hosting design tools.
