Aribam Balarampyari Devi, Manoj Kumar, Romesh Laishram

摘要:

一种复杂的数字电路,它以加法器为基本单元。电路的性能取决于这个基本加法器单元的设计。电路的运算速度是许多数字电路的重要性能指标之一,它最终取决于基本加法器单元的延迟。许多研究工作致力于改善加法器电路的延迟。在本文中,我们提出了一种改进的进位增量加法器(CIA),提高了电路的延迟性能。在CIA的设计中加入了进位查找加法器(CLA),与以往CIA设计中采用的纹波进位加法器(RCA)不同。进行了仿真研究进行比较分析。采用Verilog硬件描述语言(HDL)进行编码,并在Xilinx ISE 13.1环境下进行仿真。

英文摘要:

A complex digital circuit comprises of adder as a basic unit. The performance of the circuit depends on the design of this basic adder unit. The speed of operation of a circuit is one of the important performance criteria of many digital circuits which ultimately depends on the delay of the basic adder unit. Many research works have been devoted in improving the delay of the adder circuit. In this paper we have proposed an improved carry increment adder (CIA) that improves the delay performance of the circuit. The improvement is achieved by incorporating carry look adder (CLA) in the design of CIA contrary to the previous design of CIA that employs ripple carry adder (RCA). A simulation study is carried out for comparative analysis. The coding is done in Verilog hardware description language (HDL) and the simulation is carried out in Xilinx ISE 13.1 environment.
