摘      要：The complexity of software is ever increasing, and it requires more and more computational resources for its execution. A way to satisfy these requirements is the use of vector instructions that can operate with fixed-length vectors of data of the same. A method for representing vector instructions of one processor architecture in terms of the vector instructions of another architecture during the dynamic binary translation is proposed. An implementation of this method that includes the translation of vector addition and memory access increased the performance of the QEMU emulator by a factor greater than three on an artificial example and 12% on a real-life application.
