Architecture for quadruple precision floating point division with multi-precision support
Manish Kumar Jaiswal, Hayden Kwok‐Hay So · 2016
This paper proposes a FPGA based hardware architecture for quadruple precision (QP) division arithmetic which can also process a single, a double and a double-extended precision (SP, DP, DPE) computations. The mantissa division employs a series expansion methodology of division, integrated with a wide integer multiplier further optimized for FPGA implementations facilitating the built-in DSP blocks efficiently. The proposed division architecture is demonstrated using a Xilinx FPGA based implementation has shown a significant area saving and much improvement in latency with improved speed.
