Recent work on developing a chip architecture, suggests existing FPGAs are more suitable than earlier thought, as targets for synchronic computation. Strategically and practically this would offer considerable benefits. Consequently a pivot away from chip design, to focus exclusively on novel forms of high level synthesis is being considered.

The Synchronic Approach

By Alex Berka | 9 September 2021

Isynchronise is developing innovative approaches to languages, compilers and reconfigurable processors, arising from a novel textual language system, and associated families of formal models of computation. The basic insight is that textual programming languages have until now been based on a natural language based conception of the relationship between syntax and semantics, which historically evolved…

Public forum discussion on SC

There is some good discussion on the spatial approach and synchronic computation here; (

Interpretable Machine Learning

By Alex Berka | 6 November 2020

Interpretable machine learning is potentially landmark research. Developed originally at Duke University and then at the University of Maine, ProtoPNet provides a means of resolving the mystery of how deep neural networks classify inputs.

What future for the Von Neumann paradigm?

By Alex Berka | 28 October 2020

What future for the Von Neumann paradigm of computer architecture? AMD is to acquire Xilinx, after Intel got Altera. Is this the beginning of a shift away from ISA, or a last ditch attempt to rescue it?  

Will micro-fluidics solve thermal issues with 3D-ICs ?

By Alex Berka | 14 October 2020

The promise of monolithic 3d integrated circuits, with multiple die layers connected through monolithic vias, has been held back in part by their thermal characteristics. This research from Ecole Polytechnique Federale de Lausanne may offer a solution by combining microfluidics and electronics within the same die layer to produce a monolithically integrated cooling structure. #3dChips…

Retuning transistors to replace LUTs?

By Alex Berka | 14 October 2020

Currently logic functions in reconfigurable architectures are implemented using relatively large scale LUTs. This research from Nanjing University and the National Institute for Materials Science in Japan, shows how just several transistors making up the same logic circuit, can be tuned to implement a 2:1 multiplexer, D-latch and 1-bit full adder and subtractor. #fpgas #circuits…


BCTCS 2020

By Alex Berka | 14 March 2020

There will be a conference talk at BCTCS 2020, if it is still going ahead, on alpha-rams in April :   The alpha-ram family – bit level models for parallelism and concurrency.   Abstract   There are no bit-level machine models for parallelism and concurrency, amongst the standard formal models of computation, that permit computer…

deterministic implementation of concurrency

By Alex Berka | 29 February 2020

Deterministic treatments of concurrency are largely confined to synchronous programming for reactive systems, sometimes web based but often involving embedded devices, controlled by real time operating systems. For more general purpose computing in what are considered to be asynchronous environments, nondeterministic concurrency, expressed by process algebras and their derived languages, is often chosen. Is there an alternative to non-determinism in the general case?

Sample Page

This is an example page. It's different from a blog post because it will stay in one place and will show up in your site navigation (in most themes). Most people start with an About page that introduces them to potential site visitors. It might say something like this:

Hi there! I'm a bike messenger by day, aspiring actor by night, and this is my website. I live in Los Angeles, have a great dog named Jack, and I like piña coladas. (And gettin' caught in the rain.)

...or something like this:

The XYZ Doohickey Company was founded in 1971, and has been providing quality doohickeys to the public ever since. Located in Gotham City, XYZ employs over 2,000 people and does all kinds of awesome things for the Gotham community.
