This paper proposes dynamic streamization model execution (DSME), a dynamic vectorization technique for single instruction multiple data (SIMD) engines on multicore architectures. The technique uses stream model as intermediate representation for programs to optimize the combination of computation and memory accesses of SIMD engines in general-purpose (GP) designs. DSME allows the dynamic placement of computations on different cores when they are not in use to utilize multiple SIMD engines. This study also discusses hardware extensions to existing GP processor designs as well as related compiler extensions that use the special hardware components. Our extensive experiments demonstrate that performance gains of DSME can be achieved.
