Embodiment Construction

[0041] Preferred embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and are used together with the embodiments of the present invention to explain the principles of the present invention.

[0042] Attached below figure 1 to attach Figure 5 The method described in the embodiment of the present invention is described in detail.

[0043] During the running phase of a system, some exceptions usually occur. By analyzing and judging the on-site environment (the on-site environment includes the general register value, status register value and stack content of each cpu) when the exception occurs, we can know what is wrong with the system. Specifically, when an exception occurs, through the cause register of the cpu (the cause register is one of the status registers of the cpu, it mainly records the cause of the exception, such as memory addres...

Abstract

The invention discloses a debug method of parallel systems under a multi-core MIPS platform, which is used to solve the problems of inconvenient operation or unavailable application in the existing debug technology. The method of the invention comprises storing the field environment which arises problems and conducting the reset when the operation stage generates key problems, processing the key problems, storing the field environment of the reset field and restarting a device when confirming that the reset is caused by arising problems, restarting the device, and storing the field environment of the initial field when confirming that new debug information is generated in the initial process of the device. The method is transparent to application developers, greatly simplifies the debug complexity of the multi-core MIPS platform, is convenient for the debug, shortens the research and development period of products and saves development cost.

Description

technical field [0001] The present invention relates to the parallel technology under the platform of multi-core MIPS (Microprocessor without interlocked piped stages, without internal interlocking pipeline level microprocessor, or, Million Instructions Per Second, millions of instructions per second), in particular to a kind of multi-core MIPS platform Methods for debugging parallel systems. Background technique [0002] At present, multi-core parallel technology is becoming more and more common. The multi-core MIPS platform can provide mature solutions. Many large chip companies and Loongson also provide MIPS support, which has become the mainstream platform of modern embedded systems. MIPS is widely used in devices such as PDAs, set-top boxes, information terminals, and firewalls. It can be said that the use of multi-core MIPS embedded systems is the development direction of the future embedded field. [0003] Because each CPU running in parallel on the multi-core MIPS p...
