平方通常用于数字信号处理应用中。通过在硬件中支持平方运算，可以显著提高性能。本文提出了适用于无符号和二进制补码操作数的整数平方器的溢出检测方法。这些方法是统一的组合平方设计。所提出的方法可以适用于任何平方独立的大小和架构。所提出的平方器设计具有约50%的面积和延迟相比，传统的平方器设计与溢出检测。
Squaring is commonly used in digital signal processing applications. Significant performance increase can be achieved by supporting squaring in hardware. This paper presents overflow detection methods applicable to integer squarers with unsigned and two’s complement operands. These methods are unified for a combined squarer design. Presented methods can be applied to any squarer independent of size and architecture. The proposed squarer designs have approximately 50% less area and delay compared to the conventional squarer designs with overflow detection.
