Title: (EN) EMULATION OF TARGET SYSTEM USING JIT COMPILER AND BYPASSING TRANSLATION OF SELECTED TARGET CODE BLOCKS
Abstract: front page image
(EN)

An emulator handles problematic target code blocks by evaluating target system code for problematic target code blocks and bypassing translation of such blocks, in some cases selecting alternative host code for a problematic block. Non-problematic portions of the target system code are translated into corresponding portions of host system code, which are inserted into an execution stream. Alternative host system code may also be inserted into the execution stream.
