Abstract(in English) | This paper presents "Signed-Weight Number System (SW Number System)", which is useful for designing high-speed multiply-add modules for digital signal processing applications. The SW number system makes possible the unified representation of positive and negative numbers by adjusting the signs of individual digit positions. Compared with the conventional two's complement representation, the SW nymber representation, the SW number representation makes possible the constuction of highly regular arithmetic circuits without introducing irregular arithmetic operations, such as sign extension and LSB compensation. This paper also presents the design of a Field Programmable Digital Filter (FPDF) IC-a special-purpose FPGA for high-speed FIR filtering-based on the proposed SW arithmetic. The result of the experimental fabrication of test circuits is also described. |
