In a preemptive priority based RTOS, priority inversion problem is among the major sources of deadline violations. Priority inheritance protocol is one of the approaches to reduce priority inversion. Unfortunately, RTOS like uC/OS can’t support priority inheritance protocol since it does not allow kernel to have multiple tasks at the same priority. Although it has different ways to avoid priority inversion such as priority ceiling protocol, developers still have some difficulties in programming real time applications with it. In this paper, we redesign the uC/OS kernel to provide the ability to support round robin scheduling and implement priority inheritance semaphore on the modified kernel. As result, we port new kernel with priority inheritance semaphore to evaluation board, and evaluate the execution time of each of the kernel service as well as verify the operations of our implementation.

一般使用PC Based Controller 都是当作现场设备的一种,也就是要接受 主系统的命令,做一些操作控制。以Modbus 来看属于Slave 的角色,随 时等待接收Modbus Master 的Query Message,然后依据内容做控制,最后 将控制结果以Response Message 回传。本章将以ICP 7524 及ICP 7188E5 等 两种设备分别设计Modbus RTU、ASCII 及Modbus/TCP 的Slave 应用程序, 读者可以将此两种程序的架构再延伸设计至各种实际应用程序。
