Abstract
In this paper we present a hardware/software codesign flow
in which embedded software code is automatically
generated from system level specification of multitasking
multimedia embedded system, both for simulation and
implementation. In the proposed system design
methodology, the system behavior is specified with a
heterogeneous mixture of formal models of computation: a
dataflow model to specify the internal behavior of a signal
processing task, an FSM model to specify a control task. At
the top level, we introduce a novel task-level specification
model to represent diverse task execution semantics and
communication protocols. The generated software has a
layered structure using virtual OS APIs and OS wrapper
implementations to make it reconfigurable for multiple
target platforms. Experiments with a Divx player example
prove the viability of the proposed technique.
