Abstract :
A 16-b arithmetic logic unit (ALU) has been developed for achieving high-speed microprogrammable video signal processor LSIs. The ALU employs a parallel architecture with newly developed high-speed circuit operations, including highly parallel addition, operand look-ahead overflow detection, and carry select zero-flag detection. The unit contains 6,272 transistors in a 1.50 mm × 1.09 mm die area using 0.5-μm CMOS process technology, and 2.4-ns ALU operations have been successfully achieved
