This paper presents a new DSP-oriented code optimization method to enhance performance by
exploiting the specific architectural features of digital signal processors. In the proposed method,
a source code is translated into the static single assignment form while preserving the high-level
information related to the address computation of array accesses. The information is used in gener-
ating auto-modification addressing operations provided by most digital signal processors. In addi-
tion to the conventional control-data flow graph, a new graph is employed to find auto-modification
addressingmodes efficiently. Experimental results on benchmark programs show that the proposed
method is effective in improving performance and reducing code size.
Categories and Subject Descriptors: D.3.4 [Programming Languages]: Processors—compilers;
