For those of you that grew up with ADSR envelopes on the BBC Microcomputer or the Commodore 64 or on your Korg.

In my article Computing Without Processors http://cacm.acm.org/magazines/2011/8/114935-computing-without-processors/fulltext in the August edition of Communications of the ACM I advocate the deployment of heterogeneous computing technology to help address...

My article on Computing Without Processors is on the ACM Queue page now: http://queue.acm.org/detail.cfm?id=2000516 The article explains why it is important for us to learn to program not just regular microprocessors but also many other kinds of computing...

Every so often you have to leave the warm comfortable safe world of Haskell and venture out into what some unsavoury types call the "the real world". I've always thought it better to call the real world rather than have it call on me in Haskell-land....

In a previous blog article I showed how to get the default Ethernet address swap circuit working on the ML605 board. The address swap module (which can be generated in VHDL or Verilog) is tedious to write yourself because you have to explicitly write...

Whenever I get a new Xilinx development board I go through the tedious process of porting my circuits that use Ethernet communication to the new board. To save other people the pain I went through to get this to work I have written this blog which outlines...

Along with Anil Madhavapeddy at the University of Cambridge I've been thinking about how to apply reconfigurable computing technology (for example FPGAs ) in data-centres and in cloud computing systems. Reconfigurable computing for some time now has had...

Soon there will be so much information about our lives entered into social network systems to allow us to perform calculations with this historical data to compute "what-if" scenarios i.e. compute a parallel life we could have had if we had made some...

The ACM/SIGDA International Symposium on Field-Programmable Gate Arrays is the premier conference for presentation of advances in all areas related to FPGA technology. FPGAs for computing used to be confined to a niche market of engineers that were willing...

This blog article gives a practical introduction to how C# programs can be compiled into FPGA circuits using the Kiwi system developed by myself and David Greaves at the University of Cambridge Computer Lab. Our starting point will be a C# program developed...

The Accelerator library from Microsoft helps us write code which can execute on GPUs and multicore processors using SSE3 vector instructions. There is also an experimental FPGA target. To illustrate data-parallel programming in F# using Accelerator I...

The Kiwi project aims to automatically translate concurrent C# and F# programs into FPGA circuits for accelerated execution. I work with David Greaves at the University of Cambridge Computer Laboratory and we have a prototype system that consumes .NET...

In a previous blog post I showed how a 2D convolver can be written in F# using Microsoft's Accelerator system for GPGPU and SIMD x64 multicore programming targets. This blog article explains how the same 2D convolver can also be nicely expressed in C#...

This blog explains how Escher 's fish wood carving can be expressed in F# using functional geometry which was first presented by Peter Henderson in 1982. This very functional and compositional style of describing pictures is nicely expressed in F# . Functional...

You infer the intent in my expression, Although not always without qualification. My heart was torn between function and object, But you have rendered them as one. I've always been lazy by nature, Yet I'm drawn to your conditional strictness. ...

Microsoft recently released a preview of the Accelerator V2 GPU and x64 multicore programming system on Microsoft Connect. This system provides a civilized level of abstraction for writing data-parallel programs that execute on GPUs and multicore processors...
