Design and Feasibility of Multi-Gb/s Quasi-Serial Vertical Interconnects based on TSVs for 3D ICs

Yusuf Leblebici, Alessandro Cevrero, Panagiotis Athanasopoulos, Fengda Sun

This paper proposes a novel technique to exploit the high bandwidth offered by through silicon vias (TSVs). In the proposed approach, synchronous parallel 3D links are replaced by serialized links to save silicon area and increase yield. Detailed analysis ...

Memory Organization and Data Layout for Instruction Set Extensions with Architecturally Visible Storage

Paolo Ienne, Yusuf Leblebici, Philip Brisk, Panagiotis Athanasopoulos

Present application specific embedded systems tend to choose instruction set extensions (ISEs) based on limitations imposed by the available data bandwidth to custom functional units (CFUs). Adoption of the optimal ISE for an application would, in many cas ...

Architectural improvements for field programmable counter arrays: enabling efficient synthesis of fast compressor trees on FPGAs

Paolo Ienne, Yusuf Leblebici, Philip Brisk, Alessandro Cevrero, Panagiotis Athanasopoulos, Ajay Kumar Verma, Hadi Parandeh Afshar

The Field Programmable Counter Array (FPCA) was introduced to improve FPGA performance for arithmetic circuits. An FPCA is a reconfigurable IP core that can be integrated into an FPGA. To exploit the FPCA, a circuit is transformed by merging disparate addi ...
