Problems solved by technology

However, these sorting approaches are designed for software implementations and, in many instances, are not fit for integrated circuit ("IC") implementations, such as implementations with modern very large scale integration ("VLSI") technology.

Embodiment Construction

[0024] Reference will now be made in detail to the present embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0025] Embodiments consistent with the present invention provide a signal sorting device and a signal sorting method for sorting input signals. Embodiments consistent with the invention also provide an output sequencing device for arranging the order of sorted output signals and separating the sorted results for outputting to multiple terminals providing sampled results. In addition, embodiments consistent with the invention allow IC implementations, such as, for example, implementations with complementary metal-oxide-semiconductor ("CMOS") transistors and other devices. In some embodiments, VLSI technology is applied to implement devices consistent with the invention.

Abstract

A current sorter has an input section, a comparing section, and a control section. The input section includes a first input unit and a second input unit and generate a first output signal that is indicative of the first input signal and a second output signal that is indicative of a level of the second input signal. The comparing section is coupled with the input section and compares the first output signal and the second output signal to responsively generate a result. The comparing section includes a first comparing unit and a second comparing unit. The control section is coupled with the input section and the comparing section. Furthermore, the control section activates, when receiving an initial load signal, the first input unit, the second input unit, the first comparing unit, and the second comparing unit. Moreover, the control section deactivates, before receiving a second load signal, at least one of the first input unit and the first comparing unit when the first output signal is greater than the second output signal. In addition, the result generated by the comparing section is indicative of a level of the first output signal.

Description

[0001] 1. Field of the Invention[0002] This invention pertains to a signal sorting device and a signal sorting method, and more particularly, to a signal sorting device and a signal sorting method that can provide output signals in a predetermined order.[0003] 2. Description of the Prior Art[0004] Signal sorting devices have numerous applications in various fields of signal processing. Such devices may be implemented via a sorting network, a sorting system, or a sorting module that works jointly with other devices in a signal processing system. In general, a sorting device sorts a number of input signals, usually of unknown levels, which may be signal levels such as current or voltage levels, to generate a sorted and / or sampled result that becomes representative of he input signals in a specific order. A signal processing system then uses the sorted and / or sampled result for various applications, such as signal processing, image identification or comparison, handwriting recognition,...
