新一代实时多任务操作系统—— OSE基本概念 进程与信号 进程:Processes – functions with a context 信号:Signals – Information carriers Application High Level Approach Ease of Use Modular Design Supervised IPC Transparent IPC Error detection Memory management Functionality Application Conventional RTOS OSE
新一代实时多任务操作系统—— OSE基本概念 进程的分类 Ø Interrupt processes 中断 response-time critical task Ø Timer interrupt processes 定时器中断 high priority cyclic task Ø Prioritised processes 区分优先级的进程 longer task than interrupt processes, not directly tied to some external events Ø Background processes 后台进程 lowest level processes, used to spend leftover CPU time Ø Phantom processes 影象进程 special purpose, used mainly by OSE LNH as images of remote processes
新一代实时多任务操作系统—— OSE基本概念 内存管理 stack HIGH signals LOW SIZE 1 SIZE 2 SIZE 3 SIZE 4 SIZE 5 SIZE 6 SIZE 7 SIZE 8 用户 pool - stacks and signals 系统 pool - stacks, signals, PCB (from low mem), Uarea and supervisor stacks
新一代实时多任务操作系统—— OSE基本概念 错误处理 传统 RTOS Process 1 Process 2 Application Error code Conventional Kernel OSE Process 1 Application Process 2 SYSTEM ERROR HANDLER Application BLOCK ERROR HANDLER PROCESS ERROR HANDLER OSE Kernel 3 -Layer Error Handler 4 如果内核检测到错误, 将转入出错处理“error handler”, 允许用户集中处 理。错误处理分3层:系统(system)、块(block)、进程(progress) 4 这种方式使代码确认非常容易,因为所有的错误都以相同的方法处理
