High-Level Design of Precision-Scalable DNN Accelerators Based on Sum-Together Multipliers

Publikováno v: IEEE Access, Vol 12, Pp 44163-44189 (2024)

Precison-scalable (PS) multipliers are gaining traction in Deep Neural Network accelerators, particularly for enabling mixed-precision (MP) quantization in Deep Learning at the edge. This paper focuses on the Sum-Together (ST) class of PS multipliers

Mix & Latch: An Optimization Flow for High-Performance Designs With Single-Clock Mixed-Polarity Latches and Flip-Flops

Autor: Filippo Minnella, Jordi Cortadella, Mario R. Casu, Mihai T. Lazarescu, Luciano Lavagno

Publikováno v: IEEE Access, Vol 11, Pp 35830-35840 (2023)

Flip-flops are the most used sequential elements in synchronous circuits, but designs based on latches can operate at higher frequencies and occupy less area. Techniques to increase the maximum operating frequency of flip-flop based designs, such as

FPGA Acceleration of 3D FDTD for Multi- Antennas Microwave Imaging Using HLS

Autor: Mohammad Amir Mansoori, Pan Lu, Mario R. Casu

Publikováno v: IEEE Access, Vol 9, Pp 122696-122711 (2021)

Microwave Imaging (MI) for biomedical applications has attracted attention due to its harmless radiation compared to X-ray or MRI. One of the commonly used computing methods in MI is Finite Difference Time Domain (FDTD), which is executed several tim
