Cascaded addition/subtraction units

Definition

Cascaded addition/subtraction units are specialized components within optical arithmetic logic units (ALUs) that allow for the sequential processing of binary arithmetic operations, specifically addition and subtraction. These units enhance the efficiency and speed of computations by enabling multiple operations to be executed in a series, rather than requiring each operation to be completed independently. The use of optical technologies in these units significantly improves data processing rates due to the parallel nature of light signals, making them vital for high-performance computing applications.
