Summary: 
A novel unified phase compiler framework for embedded VLIWs and DSPs is shown. In this compiler, a given program is represented in 3-D representation space, which enables quantitatively estimating required resources and elapsed time. Transformation of a 3-D representation graph that corresponds to a code optimization method for a specific processor architecture is also proposed. The proposal compiler and the code optimization methods are compared with an ordinary compiler in terms of their generated codes. The results demonstrate their effectiveness.
