Monitoring method and system for abnormal image processing based on qsys system

Abstract

The present invention provides a monitoring method and system for abnormal image processing based on the QSYS system. The method includes the steps of: detecting the Avalon? Whether the target signal in the ST data flow signal is low level; if so, count the time when the target signal is low level to obtain the duration; when the duration is greater than the preset time threshold, the The level IP module performs the recovery operation, adopting the scheme of the present invention, it is possible to detect the hanging state of the IP module in the QSYS system in real time, and improve the image recovery efficiency.

Description

technical field

[0001] The invention relates to the technical field of image processing, in particular to a monitoring method and system for abnormal image processing based on a QSYS system. Background technique

[0002] In the field of image processing technology, the image data is collected through the decoding chip, and then the FPGA (Field Programmable Gate Array, Field Programmable Logic Gate Array) chip is used as the data processing center to cache or perform algorithmic operations on the image data, and then the MCU (SingleChipMicrocomputer, single-chip microcomputer) Computer) or CPU (Central Processing Unit, central processing unit) as the control center controls the FPGA chip and peripheral circuits to work normally, and finally makes the image data normally output to the display for display. Such a data processing mode is becoming more and more common. At present, Altera, as a large manufacturer of FPGA chips, provides a development platform based on the QSYS sys...
