Abstract :
This paper proposes a CDFG (control data flow graph) generating method from a C program for LSI design. At first, an application program described in C language is analyzed. And a hierarchical CDFG that maintains the program structure for optimal HW assignment is generated. After a generation of the CDFG, every operation in the CDFG is partitioned to data operation or address operation for design of an architecture such as DSP, which has ALU and address operation unit separately.
