Abstract

The invention claims a device and a method for tracking processor address data. The device comprises a data collection device, a trigger device, a synchronization information generating device, a data packet generating device, a data packet storing device and a data packet deriving device. The method comprises the following steps of: converting processor address data information into a processor address data packet according to a predetermined triggering condition and synchronously generating the synchronization information corresponding to the current processor address data information; storing the converted processor address data packet and the generated synchronization information; and deriving the processor address data packet and the synchronization information according to an external command. In the device and the method for tracking processor address data, the real-time collection and the quick derivation of the processor address data information are realized, the actual work influence on the processor is reduced, and it is more convenient for the research personnel to find the design deficiency on a hardware, analyze a system bottleneck and optimize programs.

Description

technical field [0001] The invention relates to a device and method for acquiring processor data, in particular to a device and method for tracking processor address data. Background technique [0002] In the software and hardware design of modern computer systems, the debugging and program analysis of software and hardware occupy a high proportion of the research and development process. [0003] The data acquisition device arranged in the processor for collecting the processor address data information collects the processor address data information according to the received instruction and sends it to the outside for analysis. [0004] In the existing online debugging method, it is difficult to quickly and batch obtain the instruction flow and data information in the execution of the program under test without affecting the normal operation of the program under test. Under normal circumstances, it will more or less affect the work of the central processing unit. Sometime...
