Abstract(in English) | In many DSPs, X-Y data transfer mode is adopted, so that two multiplication operands are efficently fed into multiplier. When these operands are not appropiately stored onto X and Y memory spaces, however, processing speed will drastically degraded. For this reason, a memory allocation suitable for X-Y data transfer mode is presented in this paper. The proposed method first formulates a interference graph from a give program, where a vertice and an edge denote a program variable and a constraint over X-Y memory assignment at multiplication, respectively. When a given graph forms a bipartite graph, optimal assignment is directly given. For a general graph, the method removes appropriate edges and assigns program variable into X and Y memory space along with the derived bipartite graph. The proposed method is applied to several example subprograms and its effectiveness is shown by the derived memory assignment. |
