Abstract

The invention provides a method for realizing reconfiguration of a global positioning system (GPS) baseband algorithm, which is characterized by being used for a reconfigurable system, wherein the reconfigurable system comprises a main processor, a reconfigurable array used as a coprocessor, a direct memory read controller module, an interrupt controller module, an external memory and a bus, wherein the reconfigurable array, the direct memory read controller module, the interrupt controller module and the external memory are connected with the main processor by the bus; and the reconfigurable array is a 8*8 arithmetic element array for accelerating the algorithm. The invention solves the problems of how to complete real-time tracking of 1ms by means of the tracking channel, how to reasonably allocate resources by capturing and tracking and how to freely switch among relevant operations, tracking loops and capturing as well as the problems of parallel processing of the tracking loops and the relevant operations and the like, thereby finishing the reconfiguration of the GPS baseband algorithm.

Description

technical field [0001] The invention belongs to the field of embedded design, a scheduling method based on the reconfigurable implementation of the global positioning system (GPS) baseband algorithm of the Nucleus (the name of an operating system) real-time operating system, and successfully realizes the multi-channel GPS baseband algorithm. The parallel acquisition and tracking of the method can be applied to the optimization of communication baseband algorithms in the design of high-performance embedded reconfigurable array system-on-chip (SoC) chips for mobile communication terminals. Background technique [0002] Today, with the rapid development of embedded systems, a new generation of applications represented by interactive media processing and high-performance mobile computing has put forward strict requirements on the performance, power consumption, flexibility, integration and cost of embedded terminals. . A new type of reconfigurable system composed of a general-p...
