Embedded Jtag Emulator Debugger

It is a focus of current computer software development that the ARM-basedembedded system is developed. With the development of technology of the embeddedhardware, embedded constant growth and embedded systematic complexity that useare improving constantly, require the scale and complexity of the embedded softwareto improve constantly. The quality of the embedded software and development periodplay decisive influence on the final quality and marketing time of the products, anoutstanding emulate debugging tool facilitation to the product quality of the softwareand development period is self-evident, so make it become the focal point that peoplepay close attention to debug tools embeddedly. We need one raise the quality anddependability of the software to embedded emulate debugging tool of field urgently,shorten the development period of the software.The goal of this subject is to design and realize a kind of tool of emulatedebugging tool based on ARM platform. This subject has carried on nowadays theembedded debugging tool of the mainstream and implementation method on thefoundation of careful and deep analysis, have accorded with the actual conditions andconfirmed the technological route and demand of the subject. Then Boundary-ScanTesting Technology, emulate device EmbeddedICE Technology and GDB remotedebug protocol RSP have been further investigated on slice to ARM7TDMI, on thebasis of totally digesting and assimilate its key technology. After solving the datavisiting, chip controlling and a series of key technology problems that the agreementis changed, we have designed and realized the embedded emulation debugging deviceLambda ODA of GDB environment of grade of a speciality.
