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 都是當作現(xiàn)場設(shè)備的一種，也就是要接受 主系統(tǒng)的命令，做一些操作控制。以Modbus 來看屬于Slave 的角色，隨 時等待接收Modbus Master 的Query Message，然后依據(jù)內(nèi)容做控制，最后 將控制結(jié)果以Response Message 回傳。本章將以ICP 7524 及ICP 7188E5 等 兩種設(shè)備分別設(shè)計Modbus RTU、ASCII 及Modbus/TCP 的Slave 應(yīng)用程序， 讀者可以將此兩種程序的架構(gòu)再延伸設(shè)計至各種實際應(yīng)用程序。

New users and old of optimization in MATLAB will find useful tips and tricks in this document, as well as examples one can use as templates for their own problems. Use this tool by editing the file optimtips.m, then execute blocks of code in cell mode from the editor, or best, publish the file to HTML. Copy and paste also works of course. Some readers may find this tool valuable if only for the function pleas - a partitioned least squares solver based on lsqnonlin. This is a work in progress, as I fully expect to add new topics as I think of them or as suggestions are made. Suggestions for topics I ve missed are welcome, as are corrections of my probable numerous errors. The topics currently covered are listed below
