An implementation of open source operating system on multiprocessor system-on-a-chip

Rich requirements from high definition television (HDTV) decoder argue the supports of complex architecture and operating system (OS). As an embedded system, multi-processor system-on-a-chip (MPSoC) is an ideal implementation of the decoder. Open source OS has many advantages to be ported to embedded fields. This paper describes the detailed process of its porting, including building environment, kernel modification, and debug. The porting specifications are constrained by the resources on the HDTV SoC platform, development period, debug efforts, and system robustness, etc. As an application of the open source OS, our work shows the joint of industry practice and theory research
