An Assembly-level Translation Scheme Towards a VLIW DSP

To simplify code migration between different architectures,an assembly translation solution towards a very long instruction word Digital Signal Processor is presented in this paper.Based on the front-end analysis,valid instructions in assembly files are mapped to machine-independent representation.Through path detection method,the delay slots are eliminated and the instruction flow graph is built,based on which the control flow graph is reconstructed.Additionally,by allocating the timestamp for each instruction,and analyzing data dependency among execution-packet,the linearizing pipelined operation is accomplished by movement and timestamps modification of instructions.The experiment indicates that the assembly programs were correctly translated to the target architecture.
