CODEC2 improvements – Single Instruction Multiple Data (SIMD)

From Wikipedia, “Single instruction, multiple data (SIMD) is a class of parallel computers in Flynn’s taxonomy.[clarification needed] It describes computers with multiple processing elements that perform the same operation on multiple data points simultaneously. Such machines exploit data level parallelism, but not concurrency: there are simultaneous (parallel) computations, but only a single process (instruction) at a given moment. SIMD is particularly applicable to common tasks such as adjusting the contrast in a digital image or adjusting the volume of digital audio. Most modern CPU designs include SIMD instructions to improve the performance of multimedia use.”

CODEC2 Improvements – Fixed Point

From Wikipedia, “In computing, a fixed-point number representation is a real data type for a number that has a fixed number of digits after (and sometimes also before) the radix point (after the decimal point ‘.’ in English decimal notation). Fixed-point number representation can be compared to the more complicated (and more computationally demanding) floating-point number representation.”
