门级静态近似加法器

Gate-Level Static Approximate Adders

P Balasubramanian, R Nayar, D L Maskell

摘要:

本文比较和分析了适合FPGA和ASIC实现的静态近似加法器。我们考虑了许多静态近似加法器,并评估其性能相对于数字图像处理应用程序使用标准的品质因数,如峰值信噪比和结构相似性指数度量。我们提供了近似加法器的误差度量,以及对应于FPGA和ASIC类型实现的精确和近似加法器的设计度量。对于FPGA实现,我们考虑了Xilinx Artix-7 FPGA,对于ASIC类型实现,我们考虑了32-28 nm CMOS标准数字单元库。虽然从这项工作的推论可以作为一个有用的参考,以确定一个最佳的静态近似加法器的实际应用,特别是,我们发现近似加法器HOAANED,HERLOA和M-HERLOA是优选的。

英文摘要:

This work compares and analyzes static approximate adders which are suitable for FPGA and ASIC type implementations. We consider many static approximate adders and evaluate their performance with respect to a digital image processing application using standard figures of merit such as peak signal to noise ratio and structural similarity index metric. We provide the error metrics of approximate adders, and the design metrics of accurate and approximate adders corresponding to FPGA and ASIC type implementations. For the FPGA implementation, we considered a Xilinx Artix-7 FPGA, and for an ASIC type implementation, we considered a 32-28 nm CMOS standard digital cell library. While the inferences from this work could serve as a useful reference to determine an optimum static approximate adder for a practical application, in particular, we found approximate adders HOAANED, HERLOA and M-HERLOA to be preferable.
