摘要： A method for detecting independent predicated instructions comprises associating all instructions within a block of code with true and false bit vectors that have bit locations corresponding to instructions that produce pairs of mutually exclusive predicates. A computation is performed in which the true bit vectors associated with the first and second instructions are EXCLUSIVE-ORed to produce a first result. The false bit vectors associated with the first and second instructions are EXCLUSIVE-ORed to produce a second result. The first and second results are then ANDed to produce a third result. If the third result is a non-zero result, the first and second instructions are independent.

摘要： A method and apparatus for reproduction of a legacy ISA application corresponding to a target ISA application state at an execution stop point are described. In one embodiment, the method includes the translation of a binary application generated for a legacy instruction set architecture (ISA) into a translated binary application for a target ISA. During translation, one or more instructions within the translated binary application are selected as commit point instructions. Once selected, the translated binary application is modified to store a source ISA application state corresponding to a target ISA application state prior to each selected commit point. In addition, the selected commit points indicate the location of the stored source ISA application state information.

摘要： A method for increasing the performance of binary translated conditional instructions. According to one embodiment of the invention, a conditional instruction compatible with the first ISA is decoded. The condition of the conditional instruction is dependent on at least on status flag. The conditional instruction is translated to be compatible with a second ISA, wherein the condition of the conditional instruction is altered to be dependent on a previously computed difference between two values, the difference residing in a memory location.

摘要： A method for enabling a first block of instructions to verify whether the first block of instructions follows a second block of instructions in an order of execution. The method includes appending a compare instruction to the first block of instructions. The compare instruction compares a first value from the first block of instructions with a second value from the second block of instructions, which precedes the first block of instructions in the order of execution. The method further includes appending a branching instruction to the first block of instructions. The branching instruction is executed in response to the first value being unequal to the second value. The branching instruction, when executed, branches to an alternative look-up routine to obtain a block of instructions that follows the second block of instructions in the order of execution.
