A real-time monitoring and analysis method, device and system for bus data

Abstract

The invention discloses a method, device and system for real-time monitoring and analysis of bus data. The method of the invention includes collecting bus data; decoding the collected bus data; writing the decoded data into a buffer; taking out the buffered data And sent to the upper computer, when collecting bus data, the clock used for sampling is the clock sent by the Master device on the bus to the Slave device, or the clock used by the Master device and the Slave device; the device includes logic devices and used to communicate with The PC interface conversion circuit connected to the upper computer, and the logic device includes a collection input terminal for connecting to the bus between the Master device and the Slave device to collect bus data. The invention can realize continuous monitoring of the bus for a long time, can automatically convert the data transmitted in the bus, and does not need human participation in analyzing the waveform content, the monitoring time does not depend on the detector itself, and the practicability and popularity are stronger.

Description

technical field [0001] The invention relates to a bus data monitoring technology of a bus communication part of a computer interface, in particular to a real-time monitoring and analysis method, device and system for bus data. Background technique [0002] In computing, a bus (BUS) is used to pass information from one module to another. And these lines connected from one point to another can actually be collectively referred to as a bus (BUS). There are many kinds of computer buses, which can be divided into high-speed bus and low-speed bus in general. For example, high-speed bus includes: PCIe bus, DDR interface bus, 10 Gigabit network interface bus, etc.; low-speed bus includes SPI interface bus, IIC bus, JTAG bus, LPC bus, UART bus, etc. These buses can realize the interconnection of two or more devices, and realize the data transmission and reception between the devices. [0003] Then when the data is transmitted on the line, once an accident occurs, the three parties...

AI Technical Summary

Problems solved by technology

However, in many cases, problems on the bus may not occur frequently, and it is very likely that they may only occur once a day or two

When faced with such a problem, the wrong scene cannot be captured, and there is no way to troubleshoot it
