Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] Before explaining the present invention, the principle of the present invention will be briefly explained.

[0035] The main idea of ​​this method comes from the single-linked list in the software data structure. The single-linked list is a structure for storing data. When accessing the data stored in the linked list, it is necessary to query a set of pointers. The content of this set of pointers is the storage of these data. Location.

[0036] attached figure 1 It is a schematic diagram of a singly linked list, the head pointer is d 0 storage location, pointer 1 is d 1 The storage location of ..., the pointer n is d n The storage location of n is a null pointer at the end. If n is a fixed number, the last null pointer may not be used.

[0037] attached figure 2 for the attached figure 1 The single linked list obtained after rea...

Abstract

This invention discloses a hardware circuit and method which can realize the sequencing of data. The circuit is used to find n the largest data from m data, m>n, and at the same time realize the sequencing of the n data. It concrete includes a register, a comparator, a multiplex chooser which can choose 1 from n+1, and two multiplex choosers which can choose one from two, and a maximum index register, and a multiplex chooser which can choose one from two, a current sampling index register, an address code converter. The talked method and equipment realize the sequencing of data by the hardware circuit which can process a data each hour, if using many circuits to work, the time of sequencing can reduce large. So the real-time processing of this circuit is strong, it can meet the higher requirement of some situation.

Description

technical field [0001] The invention relates to the field of digital signal processing, in particular to a hardware circuit and method for realizing data sorting. Background technique [0002] In digital signal processing, it is often necessary to sort a series of data, such as sorting the size order of m data, or finding the n largest (or smallest) data from m data, m≥n, to Prioritize this data. [0003] Existing technologies are mainly software sorting. Although there are many algorithms for software sorting, due to the slow computing speed of the software, it cannot meet the environment with high real-time requirements. For example, when the base station of the communication system searches for a cell, it needs to find the real signal from a large amount of data and quickly feed back the information to the mobile terminal. When there are many communities, the amount of data to be processed is very large, often reaching the order of 100,000. The software cannot search a...
