Abstract: Hardware compilation and/or translation with fault detection and roll back functionality are disclosed. Compilation and/or translation logic receives programs encoded in one language, and encodes the programs into a second language including instructions to support processor features not encoded into the original language encoding of the programs. In one embodiment, an execution unit executes instructions of the second language including an operation-check instruction to perform a first operation and record the first operation result for a comparison, and an operation-test instruction to perform a second operation and a fault detection operation by comparing the second operation result to the recorded first operation result. In some embodiments, an execution unit executes instructions of the second language including commit instructions to record execution checkpoint states of registers mapped to architectural registers, and roll-back instructions to restore the registers mapped to architectural registers to previously recorded execution checkpoint states.

Abstract translation: 公开了具有故障检测和回滚功能的硬件编译和/或翻译。 编译和/或翻译逻辑接收以一种语言编码的程序，并且将该程序编码成包括指令的第二语言，以支持未被编码为程序的原始语言编码的处理器特征。 在一个实施例中，执行单元执行包括执行第一操作的操作检查指令的第二语言的指令并记录用于比较的第一操作结果，以及执行第二操作和故障检测操作的操作测试指令 通过比较第二操作结果与记录的第一操作结果。 在一些实施例中，执行单元执行第二语言的指令，包括提交指令以记录映射到架构寄存器的寄存器的执行检查点状态，以及回滚指令，将映射到架构寄存器的寄存器恢复到先前记录的执行检查点状态。
