Attended at DATE 2016. Congradulation to my friend, Abbas Rahimi, for winnnig the Best PhD Thesis Award this year! I did a demo on eTeak at University Booth entitiled "ASYNCHRONOUS DATAFLOWS SYNTHESIS ONTO FPGAS USING THE eTEAK FRAMEWORK".

[PhD-viva]Passed the viva (aka PhD defense exam) successfully with Aii. Thanks to Prof. Jordi Cortadella for his valuable feedback.

Submitted the thesis entitled: High-level Synthesis of Elasticity: From Models to Circuits.

As Rob Pike clearly presented in his talk "Concurrency is not parallelism" and I believe this has become obvious for hardware folks in the past decade, particularly for high-level synthesis community. In this regard I have developed a CSP-model of the prime generator which has been the favorite example of the go community in the past 20 years. I have synthesised the model into hardware and the results comparing the software implementation against hardware counterpart will be released soon!

[EPSRC Doctoral Prize Fellowship] Today I was awarded the EPSRC Doctoral Prize Fellowship! This research grant, starting from December 1st, is allocated to my proposal entitled "Energy-centric Synthesis of GALS Systems". This valuable chance by the University of Manchester allows me to pursue a career in research.

[DATE'15 - eScholarID:261063] The paper titled "De-Elastisation: From Asynchronous Dataflows to Synchronous Circuits" received the DATE Best IP Award 2015 sponsored by Cadence. PDF (757K)

Back from RAL (Rutherford Appleton Laboratory) took a course on Xilinx Vivado (High Level Synthesis) design suite. Also got a ZYBO board for free which has a Zync-7000 FPGA on it with an ARM cortex-9 dual-core processor and additional CLBs. I think it's big enough to let me look at Synchronous Elastic + De-Elastisised SoCs.

I would like to wish everyone a fantástica 2015 and may all your new year's resolutions (particularly thesis write ups) come true :-)

[MICRO'14] I'm back from Cambridge, attended Micro'14. I also participated in the Hot Debate. The proposition was: It is the end of the road for the von Neumann architecture. I was quite amused with this debate. Among bebaters were Steve Furber supporting the modern architectures and Yale Patt from the opposite party supporting the von Neumann architectures (sequential systems). And my vote was a Yes! to the modern architecture.

Mission accomplished. The paper titled "Empirical Evaluation of Asynchronous Dataflow De-Elastisation vs. Synchronous High-level Synthesis", submitted to a conference... :)

I presented my work today @ the University of Manchesters' Research Symposium. Apparently the school has not considered a 'Best Presenter Award' this year, which totally pissed me off! :) btw, The slides will be available here soon.

Task accomplished: A paper entitled "De-Elastisation: From Asynchronous Dataflows to Synchronous Cicruits" submitted to a conference.

The paper entitled "Optimised Synthesis of Asynchronous Elastic Dataflows by Leveraging Clocked EDA" presented @ the 17th EuroMicro Conference on DSD'14. PDF (173K)

The De-Elasticised verion of the SSEM processor runs almost 3x faster than its asynchronous counterpart. For more information please wait for the next publication! :)

Passed the second year Viva successfully! :)

[DSD'14 - eScholarID:232298] The paper entitled "Optimised Synthesis of Asynchronous Elastic Dataflows by Leveraging Clocked EDA" got accepted in the Euromicro Conference on Digital System Design 2014. PDF (1046K)

Back from the Async'14. Now on, you can follow the updates on eTeak from here: eTeak
You can also check eTeak Demo @ ASYNC 2014. In this video a brief introduction to eTeak is given including 1) a protocol-level post-simulation visual environment based on the synchronous elastic protocol, and 2) Make FSM: which provides eTeak a mechanism to explore the design space by transforming handshake-based fine-grained structures to RTL-based FSMs through re-synthesis.

Task accomplished: Just submitted my work to the Euromicro Conference on Digital System Design 2014. For more information please wait for the next update :-)

[ASYNC'14 - eScholarID: 229597] The paper entitled "Exploiting Synchrony for Area and Performance Improvement in the Asynchronous Domain" got accepted in the ASYNC'14 Tool/Demo Session. PDF (416K)

Granted a £200 bursary from the Designing with Uncertainty - Opportunities & Challenges workshop towards Travel and Accommodation costs.

[PAnDA'14 - eScholarID:229596] The abstract entitled "High-level Synthesis of GALS Systems" got accepted in the "Designing with Uncertainty - Opportunities & Challenges" workshop. PDF (115K)

Currently I am working on a De-Elastisiser/RTL Transformer. A systematic optimisation engine to remove the fine-grained elasticity away using synchronous EDAs. I hope eventually will end up with a synthesisable polychronous framework capable of synthesising the integration of synchrony and asynchrony. The coolest part is that the designer will be able to use a unified language to fulfil this integration.

Synchronous Elastic Sparkler runs @ 1.6GHz. Sparkler is a cut-off version of SPARC v8 architecture. The Balsa description of it is implemented by Andrew Bardsley in almost 1k lines of Balsa in 2007.

My first case study was the Manchester Small-Scale Experimental Machine (SSEM), world's first stored-program computer. The Balsa description for SSEM is developed by Andrew Bardsley and it has been synthesised and tested through the Balsa synthesis system. Now I have a synchronous elastic version of it which means you don't need to be concerned about communication and computation delays. It's latency insensitive! It runs @ 740MHz with an effective CPU speed of 41.6 MIPS. Yes 38K faster than the first verion which came out in 1948!

Presented a poster in the School's Research Symposium which was sponsored by IBM. The poster propses the general idea of my research. PDF (316K)

Submitted my first year report entitled "High-Level Synthesis of Elastic Logic". It will become available online after the review process.

[ACSD'13 - eScholarID: 210181] eTeak emerged as a Synchronous Elastic Synthesis System to transform the Fine-grained Dataflow networks from the asynchronous domian to the synchronous domain.
