Paper accepted to DAC 2015

February 17th, 2015 No comments

Congratulations! Our paper “Optimizing Stream Program Performance on CGRA-based Systems,” authored by Hongsik Lee, Dong M. Nguyen, and Jongeun Lee (all currently at UNIST) is accepted to DAC (Design Automation Conference) this year. This work was in large part based on the work of Seongseok Seo, who graduated UNIST with a master’s degree one year ago. Seongseok’s primary work, which was presented at the last year’s CODES+ISSS conference, was about a light-weight yet highly effective hardware extension for mapping nested loops often found in DSP (Digital Signal Processing) applications. This work takes it to another level, developing application-level mapping strategies for stream applications with comparisons to GPU mapping results.

The DAC conference is frequently the highest ranked conference in the area of electronic design automation. It is also widely recognized as one of the most prestigious conferences in the electrical engineering and computer science discipline.

The 22nd Korean Conference on Semiconductors (KCS) is one of the largest conferences held in Korea in the electronic engineering discipline. Last year KCS attracted about 1,300 attendees from academia and industry. KCS also boasts a strong technical program consisting of about 300~400 oral+poster presentations annually.

This year the ECL lab has three oral paper presentations, on high-level synthesis presented by Atul Rahman, coarse-grained reconfigurable architecture by Hongsik Lee, and application mapping for GP-GPUs (General-Purpose Graphics Processing Units) by Dong M. Nguyen.

June 30th, 2014 No comments


Our paper, titled “Flattening-based Mapping of Imperfect Loop Nests for CGRAs” by Jongeun Lee, Seongseok Seo, Hongsik Lee, and Hyeon Uk Sim, is accepted to this year’s CODES+ISSS (International Conference on Hardware-Software Codesign and System Synthesis).

CODES+ISSS is is a premier conference for embedded systems and hardware software co-design research, and held as part of ESWEEK (Embedded Systems Week) event, which also includes CASES (International Conference on Compilers, Architecture, and Synthesis for Embedded Systems) and EMSOFT (International Conference on Embedded Software), along with a host of workshops and symposia. Congratulations again to those who did the hard work!

Asking Questions

March 26th, 2014 No comments

First I admit I myself am not a good questioner, especially in large lectures.

But I do realize the importance of asking questions as a means of learning and doing research, and encourage my students to do so (how?).

Here is a good article that may motivate you in that direction (see the bottom of the exerpt). This is on Leslie Lamport, this year’s Turing Award winner.
