Abstract(in English) | This article presents a revised architecture for full-hardwareimplementation of RTOS-based systems. In the previous method byOosako, where tasks and handlers along with kernel functions were allsynthesized into a single hardware, multiple copies of the samehardware modules were generated because the bodies of the same servicefunctions were linked with tasks and were synthesized into hardware. Our new architecture attempts to remove such duplication by migratingthe bodies of the service functions from task modules to the managermodule. For this purpose, a new mechanism for activating servicefunctions from tasks and arbitrating multiple requests is proposed. This scheme enables design of service modules in RT level, whichcontributes to reduce execution time of the service functions. Anexperimental hardware design of ``sample1'' bundled with TOPPERS/ASP3kernel shows that only small reduction in circuit size is achieved onthis instance but the execution time is reduced by more than 50 % formost of the service functions. |
