TriMedia CPU64 Application Development Environment

The architecture of the TriMedia CPU64 is based on the TM1000 DSPCPU. The original VLIW architecture has been extended with the concepts of vector processing and superoperations. The new vector operations and superoperations need to be supported by the compiler and simulator to make them accessible to application programmers. It was our intention to support these new features while remaining compliant with the ANSI C standard. This paper describes the mechanisms which were implemented to achieve this goal. Furthermore, the optimization of applications needs to address the vectorization of the functions to be implemented. Some general guidelines for producing efficient vectorized code are given.
