See the official conference page for all details of the conference.

The third annual project meeting will be held in Munich, Germany over the weekend of Saturday, October 11 and Sunday, October 12 2014.

More information on this event will be made available here and on the OpenRISC mailing lists over the next couple of months.

Presentation Proposals

We are now accepting presentation proposals.

We'd welcome presentations from anyone who is involved in the open source hardware design sphere. The OpenRISC project's concerns are many and varied, from computer architecture and RTL implementations, to open source EDA tools and flows, to tool chains, debuggers and software from bare metal RTOS to Linux user space, so we'd like to reflect this in the presentations. Your project, of course, need not be related to OpenRISC, specifically.

Presentation formats are flexible, let us know what you'd prefer and we'll be sure to accommodate you.

Please send proposals to either:

  1. OpenRISC mailinglist(s)
  2. the event organisers directly.

For questions and comments, contact us the emails above or via the IRC channel, #openrisc on irc.freenode.net.

Conference Format

The conference will likely run from about midday on Saturday to early afternoon on Sunday. This will allow people to travel Saturday morning and Sunday afternoon.

The conference will primarily consist of presentations, with perhaps a workshop allowing people to get their hands dirty with OpenRISC. We're also open to BoF sessions.

ORCONF 2013

The second annual OpenRISC project conference - ORCONF 2013.

See the schedule section for details of the weekend.

Registration

Registration is free and allows us to know who will be attending for scheduling and catering purposes.

Registration for the event is now open via Eventbrite: Click here to register for ORCONF

Please let us know any timing constraints on your attendance when registering. (set_multicycle_path -start 1hr -from {i:you} -to {i:orconf})

Audience

This meeting will be accessible for anyone with a background in embedded systems at any level, whether acquainted with the project or not.

Date & Time

The event will run from 2pm on Saturday, October 5 to early afternoon on Sunday, October 6.

Lunch will be available from 12:30 on Saturday. The sessions will run until the evening, and be followed by dinner in a local pub. Sessions will resume Sunday morning and conclude after lunch in the early afternoon.

This arrangement should allow people to travel on Saturday morning and return home Sunday evening.

Venue

University of Cambridge Computer Laboratory.jpg

This year's conference will be held at the University of Cambridge Computer Laboratory in Cambridge, England. A big thank you to David Greaves and the Computer Labs for hosting us.

The address is:

Room FW11, Cambridge University Computer Laboratory, 15 JJ Thomson Avenue, CB3 0FD Cambridge, United Kingdom

Accommodation

Some recommendations for places to stay are:

  • Travelodge Newmarket Road - they are quoting 50GBP for Friday night and 86GBP for Saturday night. It is close enough to town to walk, but is a 45-minute walk to the conference venue. Taxis between the train station and conference venue would be the best bet (if several are staying here they could be shared).
  • Arundel House - this is a well located hotel, and are quoting 77GBP per night when booked on Kayak.co.uk. The conference venue is a 25-minute walk from here.

Travel

Cambridge is well connected in the UK by train, and internationally via all of London's airports. However, London Stansted airport is the closest, and is only a 30-minute train ride from the center of Cambridge.

The Cambridge University Computer Laboratory website has a good section onhow to get there.

Cost

It is expected the conference will be free to attend, thanks to our wonderful sponsors.

Talk and workshop abstracts

A SystemC model of a multicore OpenRISC with power annotation

David Greaves, Cambridge University Computer Laboratory

David has developed a SystemC model of a multicore OpenRISC design, which has been used for teaching at the University for some years. This model is unusual in having annotations for power usage, so it can give estimates of power consumption as well as system performance when run.

Defining a Domain Specific Language for the Configuration of SoPCs Based on the OpenRISC Platform

Martin Schulze

After some words about my motivation I will give a demo of the current state of the project, the eclipse editor and a simple solution to the question how to integrate into ORPSoCv2 (yes, it's v2 for now).

OpTiMSoC - an OpenRISC-based Manycore System-on-Chip

Stefan Wallentowitz, Technical University of Munich

ORPSoC on the DE0-nano

Julius Baxter

This is a workshop first given by Julius Baxter at[chiphack.org ChipHack], showing how to bring up ORPSoC on the DE0-nano. A number of DE0-nano's will be available, but feel free to bring your own.

Partipants are encouraged to read the workshop requirements and perform the tool installation prior to arriving ORCONF. Please contact Julius Baxter via IRC, the mailing lists or directly (see email below) if you experience problems with your preparation.

Hands off the cores! Hands-on with ORPSoCv3

Olof Kindgren and others

A walkthrough to get started with using ORPSoCv3. This will precede the workshop.

OpenRISC 2000

Jeremy Bennett

This has been bouncing around for a couple of years, and it would be good to start to get some more concrete direction. Implementing OpenRISC (in silicon and in simulation) is a popular undergraduate project, and defining OR2K now might give a chance for someone to implement it during the coming academic year.

Update and discussion on the OpenRISC toolchain

Stefan Kristiansson

This year has been a lot quieter on the toolchain side than last year, but there are a couple of things of interest that could be discussed. At least one thing I have in mind is our ABI. There have been a couple of occurrences of projects that abuse the C standard for varargs, hurting us "small, different guys".

There are a couple of other things in our ABI that aren't all perfect, so maybe some venting of those issues and whether we need an "ABI v2.0" would be something we should consider.

Bug squashing session

We did this last year as the final session after lunch on Sunday. People joined in for as long as they could until their flights/trains left. It's a good chance to clear up Bugzilla once each year.
