Description: 由Jean Labrosse先生写的uC/OS的实时操作系统核心的C源代码以及说明。这是Jean先生为68HC11系列写的RTOS，但是随着越来越多的MCU的出现，Jean把他的RTOS移植到许多平台上，比较适合扩展模式的应用模式，如XA，X86，但是一些客户不知道如何使用，实在糟蹋了！不过提醒各位，这仅仅是一个核心模块，嵌入应用环境太多了，许多其他模块象：文件模块，通讯模块，显示模块等，都需要大家自己努力了！那我自己也在尝试增加一些模块，象TCP/IP协议，可以为许多应用提供附加应用。-by Mr. Jean Labrosse wrote uC/OS real-time operating system kernel of C source code and state. This is Mr. Jean wrote for the series 68HC11 RTOS, but as more and more the emergence of the MCU, Jean his many transplant RTOS platform, expansion model more suitable for the application model, such as XA, X86, but some customers do not know how to use, is wasted! But to remind you that this is only a core module, embedded application environment too much, like many other modules : File module, communications module, module, we now have our own efforts! I also try to increase their number of modules, such as TCP/IP protocol, for many applications can provide additional applications. Platform: |

Description: 多任务系统中，内核负责管理各个任务，或者说为每个任务分配CPU时间，并且负责任务之间的通讯。内核提供的基本服务
以使用实时内核可以大大简化应用系统的设计，是因为实时内核允许将应用分成若干个任务，由实时内核来管理它们。内核
用程序的额外负荷，代码空间增加ROM的用量，内核本身的数据结构增加了RAM的用量。但更主要的是，每个任务要有自己的
吃起内存来是相当厉害的。内核本身对CPU的占用时间一般在2到5个百分点之间。
UC/OS-II有一个精巧的内核调度算法,实时内核精小，执行效率高，算法巧妙,代码空间很少。-multi-tasking system, the kernel is responsible for all management tasks, or tasks assigned to each CPU time, also responsible for the communication between tasks. Kernel provide basic services to the use of real-time kernel can greatly simplify the application system design, Real-time kernel is allowed to use divided into several tasks, from real-time kernel to run them. Kernel with the additional load procedures, code space to increase the amount of ROM, the kernel data structures to increase the amount of RAM. But more importantly, each must have its own task-eating memory to be quite drastic. CPU kernel itself to the occupier of the time normally two to five percentage points between. UC/OS-II is a sophisticated scheduling algorithm kernel, real-time kernel precision small, high effi Platform: |

Description: 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.-In a preemptive priority based RTOS, priority inversionproblem is among the major sources of deadlineviolations.
