SIMD
Single instruction, multiple data (SIMD) is a type of parallel processing in Flynn's taxonomy. SIMD can be internal (part of the hardware design) and it can be directly accessible through an instruction set architecture (ISA), but it should ...

This ILLIAC's initial task was image processing of bubble chamber experiments used to detect nuclear particles. Later it was used on biological images.
The machine was destroyed in a fire, caused by a

An autotransformer is an electrical transformer with only one winding. The "auto" (Greek for "self") prefix refers to the single coil acting alone, not to any kind of automatic mechanism. In an autotransformer, portions of the same winding act as ...
shorting on one of the wooden-top benches, in 1968. It was rebuilt in the early 1970s, and the core parallel-processing element of the machine, the Pattern Articulation Unit, was successfully implemented. In spite of this and the productive exploration of other advanced concepts, such as multiple-radix arithmetic, the project was eventually abandoned.
