Efficient code synthesis from extended dataflow graphs for multimedia applications

This paper presents efficient automatic code synthesis techniques from dataflow graphs for multimedia applications. Since multimedia applications require large size buffers containing composite type data, we aim to reduce the buffer sizes with fractional rate dataflow extension and buffer sharing technique. In an H.263 encoder experiment, the FRDF extension and buffer sharing technique enable us to reduce the buffer size by 67%. The final buffer size is no more than in a manual reference code.
