摘要

En 中文

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. (C) 2007 Elsevier Ltd. All rights reserved.
