| description |
Open source software are becoming more widely-used, notably in the
server and desktop applications. For embedded systems development,
usage of open source software can also reduce development and
licensing costs. We report on our experience in developing a
Systemon- a-Chip (SoC) audio player using various open source
components in both hardware and software parts as well as in the
development process. The Ogg Vorbis audio decoder targeted for
limited computing resource and low power consumption devices was
developed on the free LEON SoC platform, which features SPARC-V8
architecture compatible processor and AMBA bus. The decoder runs on
the open source RTEMS operating system making use of the
royalty-free open source Vorbis library. We also aim to illustrate
the use of hardware/software co-design techniques. Therefore, in
order to speed up the decoding process, after an analysis, a
computing-intensive part of the decoding algorithm was selected and
designed as an AMBA compatible hardware core. The demonstration
prototype was built on the XESS XSV-800 prototyping board using
GNU/Linux workstations as development workstations. This project
shows that development of SoC using open source platform is viable
and might be the preferred choice in the future.
