Vectorization of program code

摘要

A method for vectorization of a block of code is provided. The method comprises receiving a first block of code as input; and converting the first block of code into at least a second block of code and a third block of code. The first block of code accesses a first set of memory addresses that are potentially misaligned. The second block of code performs conditional leaping address incrementation to selectively access a first subset of the first set of memory addresses. The third block of code accesses a second subset of the first set of memory addresses starting from an aligned memory address, simultaneously accessing multiple memory addresses at a time. No memory address belongs to both the first subset and the second subset of memory addresses.
