The MOLEN polymorphic processor
TLDR
A microarchitecture based on reconfigurable hardware emulation to allow high-speed reconfiguration and execution of the processor and to prove the viability of the proposal, the proposal was experimented with the MPEG-2 encoder and decoder and a Xilinx Virtex II Pro FPGA.

DWARV: Delftworkbench Automated Reconfigurable VHDL Generator
TLDR
The carried experiments on the MOLEN polymorphic processor prototype suggest overall application speedups between 1.4x and 6.8x, corresponding to 13% to 94% of the theoretically achievable maximums, constituted by Amdahl's law.

A Platform for RFID Security and Privacy Administration (Awarded Best Paper!)
TLDR
The RFID Guardian is presented, the first-ever unified platform for RFID security and privacy administration, and offers a glimpse of what system administration may be like in the future, when laymen face the responsibility to manage systems of tiny computers that they are barely aware of.

Multimedia rectangularly addressable memory
TLDR
A scalable data alignment scheme incorporating module assignment functions and a generic addressing function for parallel access of randomly aligned rectangular blocks of data is proposed and speedups close to 8/spl times/ can be expected when compared to linear addressing schemes.
