Emulation on Raspberry Pi 2

People have been emulating classic computers and games consoles on Raspberry Pi since we launched back in 2012. For those of us who bough our first hardware in the 1980s, this is a fun way to take a trip down memory lane, but our relatively modest CPU performance restricted us to third- and fourth-generation platforms. Anything with... Continue reading

Raspberry Pi 2 on sale now at $35

Let’s get the good stuff out of the way above the fold. Raspberry Pi 2 is now on sale for $35 (the same price as the existing Model B+), featuring: A 900MHz quad-core ARM Cortex-A7 CPU (~6x performance) 1GB LPDDR2 SDRAM (2x memory) Complete compatibility with Raspberry Pi 1 Because it has an ARMv7 processor,...

New QPU macro assembler

Since Broadcom released complete documentation for the VideoCore IV GPU back in February 2014 we’ve seen a number of fun uses of our 24GFLOPs of QPU compute, from Andrew Holme’s FFT library to Pete Warden’s deep learning experiments. It’s not unusual to see a 10x increase in performance over the ARM for algorithms with a... Continue reading

Controlling Telescopes with Raspberry Pi and Mathematica

Eben: Here’s a guest post from Tom Sherlock, describing how he’s been able to control a telescope using a Raspberry Pi, Mathematica and the Wolfram Language. As an amateur astronomer, I’m always interested in ways to use Mathematica in my hobby. In earlier blog posts, I’ve written about how Mathematica can be used to process... Continue reading

Raspberry Pi Model A+ on sale now at $20

When we announced the Model B+ back in July, we said that we’d also be producing a lower-cost variant, analogous to the original Model A. Since then, James has been beavering away, and today we’re pleased to announce the release of the Raspberry Pi Model A+ at a new low price of $20. Like the... Continue reading

Fresh Model B stock in production

When we announced the launch of the Model B+ back in July, we emphasized that we’d be keeping the Model B in production. Since then, we’ve been (pleasantly) surprised by the ongoing demand for Model B from industrial customers, and a couple of weeks ago some tens of thousands of new units started to roll...

New Raspbian and NOOBS releases

If you head over to the downloads page, you’ll find new versions of our Raspbian image and NOOBS installer. Alongside the usual firmware and kernel improvements, major changes to the Raspbian image include: Java updated to JDK 8 Mathematica updated to version 10 Sonic Pi updated to version 2 Minecraft Pi pre-installed Following its release...

Web browser released!

Update: Marco Barisione, who led the browser work at Collabora has written a blog post about it. Back in December 2013, we discussed our plans to develop an improved web browser for Raspberry Pi. The browser is based on Epiphany (aka GNOME Web), as a replacement for the rather venerable version of Midori in Raspbian... Continue reading

Slice – a media player using the Raspberry Pi Compute Module

We revealed the Raspberry Pi Compute Module back in April, and released the Compute Module Development Kit in the middle of June. Since then we’ve had a lot of interest and will shortly start shipping the Compute Module in volume to a variety of manufacturers who have already designed it into their products. One of...

More QPU magic from Pete Warden

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
