The FPOA, a Medium-grained Reconfigurable Architecture for High-level Synthesis

In this article, we present a novel type of medium-grained reconfigurable architecture that we term the Field Programmable Operation Array (FPOA). This device has been designed specifically for the implementation of HLS-generated circuitry. At the core of the FPOA is the OP-block. Unlike a standard LUT, an OP-block performs multi-bit operations through gate-based logic structures, translating into greater speed and efficiency in digital circuit...
