Back in June, we mentioned Pete Warden’s port of the Deep Belief image-recognition SDK to the Pi, which used the VideoCore IV QPUs to provide an accelerated GEMM matrix-multiply function. Since then, Pete’s been optimizing his code, and has reduced the time required to process an image to 3 seconds (versus 20 seconds for the... Continue reading
Meet your new favourite piece of hardware. In the two years since we launched the current Raspberry Pi Model B, we’ve often talked about our intention┬áto do one more hardware revision to incorporate the numerous small improvements┬ápeople have been asking for. This isn’t a “Raspberry Pi 2″, but rather the final evolution of the original... Continue reading
Update: As Andrew mentions in the comments below, we recently made the source for Andrew Holme’s accelerated FFT library available. I’d encourage aspiring Pi GPGPU hackers to take a look at this – it’s an incredibly tight piece of code. You may have noticed a certain lack of blog action over the last few days.... Continue reading
Update: from now on, you’ll be able to find the most recent beta release of Scratch, and report any issues, on GitHub. Since we wrote about our efforts to port Scratch to modern version of the Squeak VM back in January, Tim Rowledge has been beavering away, fixing the bugs you found and adding in... Continue reading
As many of you know, our very own Carrie Anne Philbin spent most of last year writing Adventures in Raspberry Pi. For some reason she keeps reminding me that, with 4.8 stars out of 5, it’s currently the highest-rated Raspberry Pi book on Amazon; I can’t imagine why. The last few chapters of the book...

A few days ago, we pushed out some more documentation for the forthcoming Compute Module and Compute Module IO Board, which together make up the Compute Module Development Kit. This new documentation covers power supply and sequencing requirements, temperature limits, and the process for writing an operating system image onto a module; and provides a... Continue reading
One of our goals in launching the Raspberry Pi Compute Module was to provide people with a way to take products they’ve prototyped with the Raspberry Pi and bring them to market quickly and easily. We know that historically there have been a lot of people out there with great ideas for electronic products that... Continue reading
On May 1, 1964, Professor John Kemeny ran the first BASIC program from a timesharing terminal at Dartmouth College, and ushered in a new era in accessible programming. Growing up in the 1970s and 1980s, BASIC tended to be the first language that children of my generation came across; despite well-known claims to the contrary,... Continue reading
Some of you will be aware that we’ve been working on a new, more responsive and more modern desktop experience for the Raspberry Pi. We thought you might like an update on where we are with the project. The chip at the heart of the Raspberry Pi, BCM2835, contains an extremely powerful and flexible hardware... Continue reading
At the end of February, Broadcom announced the release of full documentation for the VideoCore IV graphics core, and a complete source release of the graphics stack for the BCM21553 cellphone chip. To celebrate, we offered a $10k prize to the first person to port this codebase to the BCM2835 application processor that sits at... Continue reading
