The Analysis And Research Of A Virtual Machine Based On SDP2005

As the development of digital technology, the middleware comes into being.They can isolate the application and the underlying operating system along with thecomplicated hardware details, supporting the running of application from oneoperating system and platform to another, and make it possible that a application canwork without a certain hardware platform and system. Up to now, the JVM and JAVAHTML VM are indeed in fashion.At the beginning of this thesis, we pay much attention to the research of virtualmachine and how to set up a run-time system along with the procedure of a assembler.Then , based on it, we transplant a subset of the instruction set for HEC VM as well asthe instruction handlers, workout the initializer and the main handler for a VM withthe emphasis of platform-depend codes,and also the executing environments. Andthen, complete the menu for controlling it and sending run-time parameters. In orderto make the interrupt system sense, we design a VM event handler as the graphicAPI. .And finally, we try to workout a debugger to achieve the step-by-step debuggingof it .This thesis firstly introduce the STB and JVM, then give a brief account of theBSP(Board Support Package)'s work flow and function caller and callee relations .And then in chapter 3,we discussed how to set up a run-time system on our platformand how to transplant it. And then we put the content of how to design a graphicinterface for the VM and how to build user menu in chapter 4.At last, we design adebugger completing the debugging works and give the testing results. Finally inaddenda 2,we draw a brief flow of how the assember works out by reading the sourcecodes.
