| Abstract: |
| In the first part of this paper, an analysis of the characteristics of data schedule under nested loops is presented. Three aspects which include the significance of the fulfillment of data accessing by the address counter, the principles of ILSP (interlaced inner and outer loop software pipelining) algorithm and under the idea of ILSP algorithm are presented. And a discussion of the data scheduling characteristics is given. In part 2, the key steps of how to derive the data addressing control sequence from the applications is listed. In part 3 and part 4, the authors respectively discuss how to apply the sequence of data accessing control to control the address counter and how to simplify the data accessing control sequence to the reduced data accessing control sequence. The part 5 is experiment results and part 6 is conclusion. |
