Imagination conversion and application of the transaction memory hardware which urges emulation

摘要

Various technologies and technique in order to use the transaction memory hardware which makes imagination conversion or emulation easy are published. On the transaction memory hardware, it offers the secret state which is isolated, it is possible by the fact that stack of host which executes emulation in the secret state which is isolated is retained to make the isolation of state easy. The guest who is emulated self rewriting of the cord/code sequence of the guest himself with the software in order to detect the thing which does can watch the memory access which is executed by CPU. Making use of the function of atomic commitment, it can use the transaction memory hardware in order to make the renewal of the dispatch table easy in multithread operation environment. In order to convert guest program counter to host program counter, the emulator which uses the dispatch table which is retained in main memory is offered. In order to know whether or not the dispatch table, includes the host program counter of specification for guest program counter of specification, it accesses the dispatch table.
