This category is for minimal processors: CPUs that use various design strategies to strongly minimize the component count needed to do work; to be as simple as possible. This includes: MISC (Minimal Instruction Set Computers), SISC (Simple Instruction Set Computers), ROSC (Removed Operand Set Computer), ZISC (Zero Instruction Set Computers), Forth and stack processors, and other methods. This was one of the original goals of RISC (Reduced Instruction Set Computers), but many newer RISC processors are more complex than the original CISC (Complex Instruction Set Computers) processors they challenged, and some current CISC processors are astonishingly complex. Minimal processors will be very useful in, and may become important for, mobile and ubiquitous computing.
