In recent years

lots of fruitful results have been achieved in the aspects of simulation technology for embedded hardware and virtual testing for embedded software. However

there are some shortcomings in the previous achievements. For example

there are no overall

unified

flexible and general interfaces among the generic components

so it results that different architecture or different type of simulation processors cannot interact and integrate with simulation devices directly

and result that system-level customization capabilities are lack. Based on component

a set of general structures

standard interfaces

processing logics for virtual processors

virtual peripherals and debugger are proposed. We did some optimizations and deletions

added some new features in GDB

so that GDB can dynamically load at runtime to support multiple processor architectures. A virtual testing system is developed

by it the validity and correctness of the proposed method

structure

interfaces are verified. The proposed methods and technologies have more advantages compared with other similar technologies or projects.
