20 results about "Belt machine" patented technology

In computer engineering and in programming language implementations, a belt machine is a real or emulated computer that uses a FIFO queue rather than individual machine registers to evaluate each sub-expression in the program. A belt computer is programmed with an instruction set that specifies arguments explicitly but results implicitly. The common alternative to belt machines are register machines, in which each instruction explicitly names the specific registers to use for operand argument and result locations. Belt machines are related to stack machines, which specify both arguments and results implicitly using a pushdown stack. A belt machine implements temporary storage with a fixed-length FIFO queue, or "belt" by analogy to a conveyor belt. The operands of the arithmetic logic units and other functional units may be taken from any position on the belt, and the result from the computation is "dropped" in the front position of the belt, advancing the belt to make room.
