Problems solved by technology

Due to the limitations of recording speed and anti-seismic ability, optical discs cannot be used for debugging and real-time data recording of digital signal processors, and hard disks cannot meet the requirements for debugging and real-time data recording of digital signal processors because of their weak anti-seismic ability and strict requirements on working temperature. data logging needs
The current electronic disk technology is not designed for the real-time data recording requirements of the digital signal processor, and there are shortcomings such as slow data transmission speed with the digital signal processor, slow recording speed, and inability to automatically recycle "outdated" data.

Embodiment Construction

[0018] Flash memory array storage method for real-time data logging of digital signal processors,

[0019] (1). The information exchange channel between the digital signal processor and the module used for real-time data recording of the digital signal processor adopts the link port (Link Port) of the SHARC DSP chip;

[0020] (2). The storage medium of the flash memory array of the module used for digital signal processor real-time data recording is a NAND (NAND Flash Memory) flash memory chip.

[0021] The NAND flash memory array is composed of 2-64 pieces of NAND flash memory chips, and the NAND flash memory array is grouped. Each group has the same size. Before each use, select 2-32 groups for recording according to the recording amount required by the digital signal processor. Data, and query the NOR (NOR Flash Memory) flash memory, find out the required number of groups that have not been used for the longest time to record the data, and the usage of each group is stored ...

Abstract

A method for storing flash memory array recording real time data of digit signal processor includes applying link port of SHARC DSP chip an information exchange channel between digit signal processor and module recording real time data of said processor, using NAND flash chip as storage media of flash memory array on module for recording real time data of said processor. The module for recording real time data of the process or consists of control circuit with SHARC DSP chip, storage circuit with 1 ¿C 2 pieces of NOR flash memory chip and NAND flash memory array and interface circuit with socket and matching resistance.

Description

technical field [0001] The invention relates to a data recording method of a digital signal processor and a module thereof, in particular to a data storage method of data / signal processing systems such as radar, sonar signal processing, and real-time control. Background technique [0002] At present, mass storage devices can adopt optical disks, hard disks and electronic disks. Due to the limitations of recording speed and anti-seismic ability, optical discs cannot be used for debugging and real-time data recording of digital signal processors, and hard disks cannot meet the requirements for debugging and real-time data recording of digital signal processors because of their weak anti-seismic ability and strict requirements on working temperature. data logging needs. The current electronic disk technology has not been designed for the real-time data recording requirements of digital signal processors, and there are shortcomings such as slow data transmission speed with digi...
