- Abstract
- Automatic code synthesis from dataflow
program graphs is a promising high-level design methodology for
rapid prototyping of multimedia embedded systems. Memory
efficient code synthesis from dataflow models has been an active
research subject to reduce the gap in terms of memory
requirements between the synthesized code and the handoptimized
code. However, existent dataflow models have inherent
difficulty of efficiently handling data structures. In this paper, we
propose a new dataflow extension called fractional rate dataflow
(FRDF) in which fractional number of samples can be produced
and consumed. In the proposed FRDF model, a constituent data
type is considered as a fraction of the composite data type.
Existent integer rate dataflow models can be easily extended to
incorporate the fractional rates without loosing analytical
properties. In this paper, the SDF model is extended to include
FRDF, which can reduce the buffer memory requirements
significantly, up to 70%, for some multimedia applications.
