OS Structures OS Basics RTOS Basics Basic Facilities Interrupts Memory Development Methodologies Summary References. • Host generally machine with a proven General Purpose Operating System (GPOS), Development Methodology • Better development environment • Debugger is on host while application is executed on target • Debug agents are stored on target to communicate with host • Simulator should be provided to execute prototype application on the host • Hybrid • Host and target on same machine but on different OSs • Communicate via shared memory, Development Methodology • Resource and hardware shared • May prevents RTOS from predictable behavior • May prevent GPOS from housekeeping duties • Multiprocessor environment should improve performance, Summary • A RTOS should be predictable regardless of the system load and size of queues/lists • RTOS should always support pre-emptive priority scheduling • The memory model utilized is very important to the performance and predictability of your RT system, © 2020 SlideServe | Powered By DigitalOfficePro, - - - - - - - - - - - - - - - - - - - - - - - - - - - E N D - - - - - - - - - - - - - - - - - - - - - - - - - - -.
