Abstract
Currently, codesign methodologies and
techniques are being proposed for the design
of SOC both in academia and in industry.
One of the most urgent tasks at this time is to
allow a smooth transition from IC design to
system design, which requires a
hardware-software codesign methodology
and a tool for designers to easily design their
highly complex designs before the actual
costly fabrication. With this goal in mind, we
are developing a hardware-software
(H/W-S/W) CO-design tool for multimedia
system SOC.
Implementing a multimedia system can
be divided into two different portions:
software portion and hardware portion. Due
to the higher cost in developing hardware, the
designer would usually prefer to implement a
system mostly by a software-solution. Only
the functions that have a higher performance
requirement or a tight timing constraint
would be implemented as hardware. In this
report, we propose a system/function level
hardware/software partitioning method to
perform system partitioning for multimedia
applications. We also use JPEG2000 coding
system as an example to demonstrate how to
perform design space exploration by using
our methodology to obtain an optimal system
partitioning that can satisfy user defined
design constraints. Our partitioning method
could not only be used in traditional
hardware/software codesign flow, but also
can be used under the integrated platform-based function-architecture
codesign.
