Intel IPP is divided into four major processing groups: Signal (with linear array or vector data), Image (with 2D arrays for typical color spaces), Matrix (with nxm arrays for matrix operations), and Cryptography.
Half the entry points are of the matrix type, a third are of the signal type and the remainder are of the image and cryptography types. Intel IPP functions are divided into 4 data types: Data types include 8u (8-bit unsigned), 8s (8-bit signed), 16s, 32f (32-bit floating-point), 64f, etc. Typically, an application developer works with only one dominant data type for most processing functions, converting between input to processing to output formats at the end points.
