ABSTRACT:
An architecture and method for emulating guest instructions with host instructions, executable on a host computer, based on a translation scheme. The architecture includes a guest instruction memory and program counter and a RAM memory storing host instructions, in which an address word stored in the program counter is mapped to the RAM memory to access the host instructions. The method constitutes dynamically recompiling (DR) host instructions including providing one memory which stores host instructions, providing in other memory having line entries for storing a fixed number of dynamically recompiled host instructions, and copying a host instruction from the one memory into a line entry of the other memory.
