The first digital differential analyzer was the MADDIDA developed in 1949 at the Northrop Aircraft Corporation. It had 44 integrators implemented using a magnetic drum for storage, the addition being done serially. There were six tracks in all on the drum, one being Description Digital Differential Analysers presents the principles, operations, design, and applications of digital differential analyzers, a machine with the ability to present initial quantities and the possibility of dividing them into separate functional units performing a number of basic mathematical operations. In computer graphics, a digital differential analyzer (DDA) is hardware or software used for interpolation of variables over an interval between start and end point. DDAs are used for rasterization of lines, triangles and polygons. Digital differential analyzer is a line drawing algorithm that is based on incremental method, which calculates all intermediate points over the interval between start and end points.

The DDA starts by calculating the smaller of dy or dx for a unit increment of the other. Unlike earlier DDA's, the parallel digital differential analyzer, we believe, combines more of the best fea tures of analog and digital machines: It boasts speed, accuracy, and ease of programming. Because the machine itself is entirely digital, it couples naturally and inexpensively with convention al digital computers. than analog differential analyzers or any of the general purpose digital computers.

In computer graphics, a hardware or software implementation of a digital differential analyzer (DDA) is used for linear interpolation of variables over an interval between start and end point. Digital Differential Analyzer (DDA) algorithm The Cartesian slope-intercept equation for a straight line is with m representing the slope of the line and b as they intercept.
