Memory Team has Two Papers Accepted at DATE 2015

The notifications from the DATE conference are in and the Memory Team scores 2 out of 2, just like in 2014. The first paper entitled “A Generic, Scalable and Globally Arbitrated Memory Tree for Shared DRAM Access in Real-Time Systems” was first-authored by Manil and is a collaboration with Jamie Garside and Neil Audsley from University of York. The paper proposes a memory interconnect for shared memory architectures in many-core systems. A main architectural feature is that the interconnect is heavily pipelined enabling it to be synthesized at high frequencies even with a large number of clients. Another highlight is that it has global arbitration that can be programmed to behave like several different arbitration mechanisms, such as TDM, CCSP and FBSP.

The second paper “Retention Time Measurements and Modelling of Bit Error Rates of WIDE I/O DRAM in MPSoCs”was first-authored by our colleagues at Kaiserslautern University of Technology in collaboration with Sven Goossens from our Memory Team. This paper looks into the thermal behavior of 3D-stacked WIDE I/O DRAM and compares its impact on retention time and bit error rates to conventional 2D DRAM chips.

Memory Team Scores Four out of Four Accepted Papers at DATE 2013!

The preliminary author notification for DATE 2013 is now available on the conference website and it reveals that the memory team scores an incredible four accepted papers out of the four submitted, resulting in an acceptance ratio of 100% for the team! The four paper titles are:

The papers cover topics ranging from memory controller architectures, configuration, and power modeling for Wide I/O memories to open-page policies in real-time memory controllers and a comparison between the tightness of bounds for the latency-rate abstraction and cycle-accurate simulation. These papers are also evidence of the many recent successful collaborations as there are authors from CISTER-ISEP Research Unit, Fortiss, and the Technical Universities in Eindhoven, Kaiserslautern and Munich.

Karthik Chandrasekar Receives HiPEAC Collaboration Grant

Today, we celebrate that Karthik Chandrasekar has received a 3 month HiPEAC collaboration grant to visit the group of Prof. Norbert Wehn at Kaiserslautern Institute of Technology. The application process was competitive with approximately 30% of 67 proposals being funded. The grant serves to extend the existing collaboration between our two groups and will be used to conduct research on the hot topic of “Mobile and 3D-Stacked Wide I/O DRAM Power Modeling and Optimization”.
