A queue is a data structure that takes its name from a physical queue, such as at a supermarket. Items are inserted into a queue at one end and removed at the other. This principle is often referred to as FIFO (which stands for First In First Out) because the first item into the queue is the first one out.

Abstract
Mobile processors are used in numerous embedded systems, including laptops, personal digital organizers, wearable computers, cellular phones, mobile Internet terminals, digital cameras, digital cam-coders, smart cards, and sensor networks nodes. Although these systems differ in terms of their communication and computation requirements, they share the common need for low power, security and small memory footprint. This chapter presents the software and hardware architecture and the design results of a low power processor architecture based on queue computation model, which offers an attractive option in the design of mobile and embedded systems.
