Abstract:
A selected group of Guest machine instructions in an emulation environment are translated to a semantic routine of Host machine instructions, wherein Guest cells corresponding to an opcode portion of a Guest instruction are mapped to corresponding Host cells, wherein the semantic routine of Host machine instructions are patched into a Host cell corresponding to the first Guest cell of the group of Guest machine instructions, wherein other Host cells of the corresponding Host cells are patched with semantic routines for emulating single instructions associated with the corresponding Guest cell.
