ChipHack EDSAC Challenge – Hebden Bridge 6/9/2017

ChipHack

ChipHack EDSAC Challenge is a workshop spanning two-and-a-half days to introduce a new generation to silicon chip design and the historic EDSAC computer.

This workshop is suited to complete beginners, as well as people who are experienced chip designers.

With modern low cost FPGA boards silicon chip design is accessible to the individual engineer, whether professional, hobbyist or student.

This workshop starts from the basics (a chip design to flash an LED), works through more complex functionality (UART transmitter and receiver) and concludes by bringing up a complete processor.

The workshop will be built around a reimagining of EDSAC (designed by BCS founding President, Prof. Sir Maurice Wilkes) using modern technology. The workshop will use the MyStorm FPGA board, a modern low-cost board for educational use. (more…)

Getting started with NetBSD on embedded platforms – London 20/4/2017

NetBSDOn the 20 April 2017, 17:30 – 20:00 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA, [map] (51.510812, -0.121733)

Please register to attend and share on Lanyrd.

Workshop scope

You’re hired at the latest startup as a hardware engineer and required to build the firmware which will run on “The Greatest Next Generation Appliance” (GNA). The GNA boots, prints a message and interacts with a device (in this case an LED).

In this workshop we cover how a person with an interest and a focus on hardware can make progress with the software side by using the NetBSD operating system and the features it offers to save considerable time and effort.

  • NetBSD supports a wide & diverse range of systems & CPU architectures.
  • Support for cross compilation is offered by default and works out of the box.
  • There is a high level language interface to interact with the system internals.
  • File integrity verification support to detect tampering of binaries and preventing execution is builtin.
  • An instance of the kernel can be run as a user process on different operating systems where rapid development can take place.

Things we will cover:

  1. An introduction to cross-compilation with build.sh and constructing an image to boot on your hardware.
  2. Interacting with the system using Lua (which is embedded in the kernel, avoiding having to write C or have knowledge of OS internals) to e.g. access GPIO.
  3. Preventing the execution of tampered or unauthorised binaries with veriexec.
  4. Using rump kernel for rapid development away from a potentially slow dev board.

An introduction to software-defined radio with LimeSDR – London 24/3/2017

On the 24 March 2017, 09:00 – 17:00 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA, [map] (51.510812, -0.121733)

Please register to attend and share on Lanyrd.

A Software-Defined Radio (SDR) is a highly reconfigurable radio that can be used for many different radio applications through simply changing the software that links with it. An example of such a reconfigurable radio is the LimeSDR, which can both transmit and receive data and voice, using just about any wireless system.

The LimeSDR was launched by Lime Microsystems in May 2016 via a crowdfunding campaign, and is now shipping to over 3,500 customers worldwide. It is based on the Lime Microsystems LMS7002M Field Programmable RF (FPRF) 2×2 MIMO transceiver, which continuously covers frequencies from 100kHz to 3.8GHz. The LMS7002M has been successfully used in a wide range of digital radio applications, including 2G/4G Femtocell base stations, GNSS, DAB, DVBT receivers and RF test and measurement equipment. The LimeSDR also includes an FPGA and USB 3.0 to provide host connectivity.

Workshop scope

LimeSDRThe heart of the day is to provide a practical ‘hands-on’ afternoon session using the LimeSDR with the Lime Suite GUI and FFT Viewer. Then to use GNU Octave and Pothos to make some very simple digital radio examples.

To facilitate this, the morning will include introductory talks explaining the purpose of the various analogue and digital blocks included in the LMS7002M. It will also include tutorial material covering the key concepts required to understand modern digital radio transceivers, and how to use them, as well as practical issues associated with radio reception.

In addition the day will feature some advanced demonstrations showing the full capabilities of the LimeSDR and its LMS7002M transceiver, including 4G Femtocell, as well as educational examples such as a simple OFDM transceiver data link.

FPGA projects past, planned and possible – London 16/2/2017

On the 16 February 2017, 18:00 – 20:00 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA,[map] (51.510812, -0.121733)

Please register to attend and share on Lanyrd.

The fifty-fifth meeting will feature a series of shorter talks that explore past, planned and possible projects which use FPGAs.

FPGA Projects – What would I build and why would I want to

PLAs have been interesting ever since the 70s when digital logic often became complex, consuming unnecessary space and power. Back then the cost of PLA deployment was high and it has continued to be high until recently. Now that we have powerful, low cost development platforms and relatively cheap FPGAs the cost equation has shifted radically.

Paul Tanner is a consultant, developer and maker in wood, metal, plastic, electronics and software. His day job is IT-based business improvement for SMEs. By night he turns energy nut, creating tools to optimise energy use. Paul graduated in electronics and was responsible for hardware and software product development and customer services in several product and service start-ups, switching to consulting in 2000.

Using FPGAs to solve realtime problems

Microcontrollers a great platform to solve basic control problems in electronics, with simple motor drivers and sensors readily avaiable and easy to integrate. However, when the motor control becomes more complex with BLDC and FOC things get much more tricky. When you have to use multiple BLDC motors and more complex sensors with image processing the poor microcontroller quickly becomes to swamped to provide control in realtime. This is where adding FPGA technology makes a great deal of sense particularly in mutli-discipline projects like robotics where many sensors, motors and image processing will need to be managed and controlled concurrently. A robotics platform must therefore contain both concurrent hardware resources, algorithmic control through soft or hard cores along with communication protocols.

Alan Wood has been working with parallel distributed programming for several decades. His recent work includes smart grids, 3D printers, robotics, automation and biotec diagnostics. His current research is focused on machine learning, inference and image processing for embedded applications using FPGA and multi-cores. He is a long term advocate and moderator (aka Folknology) for xCORE and other opensource communities, as well as a founder of Surrey and Hampshire Makerspace and myStorm FPGA development boards.

FPGAs in the Cloud?

It is no secret that FPGA based computing machines are great at dealing with certain types of workloads that conventional CPU based machines can not efficiently handle. These machines, alongside their GPU and even custom ASIC based brethren, have been filling up racks in large data centres all over the globe helping speed up systems that have components of machine learning, complex analytics and even video processing.

This short talk will have a look at the state of FPGAs in the datacenter and discuss the recent developments around the availability of FPGA equipped computing nodes in commodity cloud providers.

Omer Kilic is an Embedded Systems Engineer who enjoys working with small connected computers of all shapes and sizes. He works at the various intersections of hardware and software engineering practices, product development and manufacturing.

Chip Hack 2017 & EDSAC Challenge

This talk will introduce and issue a call for participation for two events that are being hosted as part of the Wuthering Bytes technology festival, that will take place in Hebden Bridge in September, in the week following Open Source Hardware Camp 2017.

Chip Hack is a two day hands-on workshop that provides a gentle introduction to programming FPGAs and is aimed at novices with no prior experience of Hardware Description Languages (HDLs) or FPGAs. This will be followed immediately by a challenge event, during which a small team of experts will work to extend a basic functional FPGA model of EDSAC — the pioneering computer designed and constructed at Cambridge University, and which was operational by 1949.

Deploying your FPGA toolchain consistently regardless of your development environment

With an open source tool chain for an open hardware fpga, we’re free to work in the environment of our choice. What may differ between platforms is how we put the components together, from requiring software dependences to administrative commands needed to be executed in order to build to software successfully.

pkgsrc is a cross platform packaging system which allows you to deploy open source software consistently, regardless of the environment it is operating on. This means should you desire to install the icestorm tool chain, the steps required to build or install packages is the same whether you’re running a flavour of Linux, Mac OS or Windows.

This lightning talk will introduce pkgsrc and how you can get started quickly with icestorm and other tools to help with your hardware project.

Sevan Janiyan is founder of Venture 37, which provides system administration & consultancy services. As a fan of operating systems and computers with different CPU architectures, in his spare time he maintains builds of open source software on a variety of systems featuring PowerPC, SPARC and armv7l CPUs. He hopes to own a NeXTcube & OMRON LUNA-88K2 one day.

Multicore Made Simple – Conducting a Chorus of Cores on an FPGA

FPGA technology makes it simple to build a multicore CPU, by instantiating multiple copies of a soft processor design on a single chip. The challenge is to connect and coordinate the cores into a resource which is useful for application programming. While traditional multicore processors include shared memory, shared buses and/or general communications networks, all of these are costly in hardware resources and complexity, and subtle details of synchronization and cache coherency can make programming difficult and risky. Building our own system on an FPGA, we can choose a minimalist “shared nothing”
architecture, with only local memories and simple synchronous point to point communications links in a topology tailored to the application. As an example of this approach, I’ll demonstrate a 40 voice (plus
conductor) polyphonic digital audio synthesizer, running on an array of
41 Nios2 cores on an Altera Cyclone II.

Dr Richard Miller has had a long career in the borderlands between hardware and software, in academia and industry and now as an independent consultant. Particular interests have been operating systems portability (starting in 1977 with the world’s first UNIX port, from
PDP/11 to Interdata 7/32 at the University of Wollongong; and most recently porting the Plan 9 OS to the Raspberry Pi); programming language implementations in constrained environments (e.g. a LOGO interpreter on a 48KB Apple II; and a JavaCard JVM and runtime library on a smartcard with a 8KB of RAM and 1MB of flash); parallel computing infrastructure (on hardware ranging from Transputers to the Cray T3D); and embedded systems firmware (e.g. a complete Bluetooth stack for a range of prototype phones and tablets). Current work in progress includes building a communications network on an FPGA, for a microcluster of Raspberry Pi Zeroes.

Note: Please aim to arrive by 18:15 as the event will start at 18:30 prompt.


Personal Privacy Online (The Dark Web, Investigatory Powers Act) – London 19/2/2017

Date: 19 January 2017, 18:00 – 20:00
Venue: BCS London, 1st Floor, The
Davidson Building, 5 Southampton Street, London, WC2E 7HA.

Registration:  https://events.bcs.org/book/2408/

NB Closing date for bookings is Tuesday 17th January 2017 at 11:59 pm. No more bookings will be taken after this date.

For this meeting we explore the theme of personal rights and privacy on the modern Internet, with a talk on The Dark Web, covering insights on one of the larger anonymous marketplaces online and another on the new Investigatory Powers Act. All are welcome. This meeting is open to the public, but registration is required.

The Investigatory Powers Act: What is it?

The Investigatory Powers Act also known as the Snoopers Charter is now law, find out what that means for you and your company. The Snoopers Charter would require metadata on every email, website visit and social media log to be recorded. It covers hacking and mass hacking performed by Government agencies. Its powers can be enforced across the world. It contains over 270 clauses and dwarfs the computer misuse act in terms of size, so this is going to be a speed run covering some of the high points.

Glyn Wintle is a security evangelist and software engineer. He has given evidence in Parliament, frequently gives technical talks about security and is well know for his work with the Open Rights Group.

The Dark Web

Dark web markets

This talk will presents a research carried out to gain insights on the products and services sold within one of the larger marketplaces for drugs, fake ids and weapons on the Internet, Agora, and on new developments after the demise of Agora.

The team behind the research included Andres Baravalle, Sin Wee Lee, Germans Zaharovs (research intern) and Mauro Lopez Sanchez (final year project).

The work has been featured on the front page on The Times and on the Guardian, amongst other media.

Andres Baravalle works in the in the University of East London as Senior Lecturer in Computing.
He has been working in academia since 2004 (University of Turin, University of Sheffield, Open University, University of East London), while also working as a contractor in industry.

Andres has been developing in LAMP environments since 1999 and managing development teams since shortly after. In the past years he has been combining his expertise in web technologies with an interest on security and data science.

He once made a student cry – by praising his work.

Update: slides are now available here.
