There is a trend f o r the irforniatioti products that irltegrated by coniputeK cnniriiuriicatiori, arid consiinier electronics. The OS is required more coniprrct andpmctical. An embedded systeni STARTH is cleveloped and based ori the core o j the Motorola PPSM that is a red tinie 32-bit kernel with prioritized iriterrirpt scheduling. All tasks Lire iriterrirpt-clriveti. The PPSM kernel does trot access hardnuire device directly. The kertiel controls nll peripheruls itidirectl?, through softww-e device drivers. The PPSM tools consist of peti input. grciphics. database. text, character input, system and coniniirnication. The PPSM toolsets, together with its device drivers, provides the basic control of the LCD, the clruwitig functions. the real time clock arid the UART Here the architecrure of the enrhedded systeni STARTH on the Drclgon Bull EZ platform is discussed in parts in cietrrils. The rlevelopnietit etivirotinietits of both stgivare arid hardrvare are described The systeni is analyced froni its initialization, registration to systeni nianngenient, eveti the cipplicatiotis prograninring. The STARTH is tested unrl rwi on the licrrdrvcrre systeni of Drugon Ball plntforni. It denionstrates that STARTH is practical arid reliable for persorial irforniatioti devices.
