uC/OS-II Notes from Nohau Corporation The code associated with this readme.txt file is provided "as is". The code was written with the intention of creating a functional RTOS demo for the Nohau evaluation boards that can run a MicroBlaze core. You can use this code for any and all of your projects, as you see fit. Nohau Corporation does not warrant that the code is bug-free, and will provide no supPort for this RTOS Port.

Spartan 3 Digilent Demo:This demo drives the perphrials on the Spartan 3 board. This drives a simple pattern to the VGA Port, connects the switches to the LEDs, buttons to each anode of the seven segment decoder. The seven segment decoder has a simple counter running on it, and when SW0 is in the up position the seven segment decoder will display scan codes from the PS2 Port. This demo how ever does not drive the RS-232 Port or the memory. This is a simple design done entirely VHDL not microblaze.

VerboseGC demonstrates the use of the java.lang.management API to print the garbage collection statistics and memory usage remotely by connecting to a JMX agent with a JMX service URL: service:jmx:rmi:///jndi/rmi://<hostName>:<PortNum>/jmxrmi where <hostName> is the hostname and <PortNum> is the Port number to which the JMX agent will be connected.

The sfloppy sample is a super floppy driver that resides in the directory \\Ntddk\Src\Storage\sfloppy. It is a class driver for Super Floppy disk drives. It sits a level above the Port driver (ATAPI, USB, etc) in the driver stack, and brokers communication between the application level and the Port driver. The floppy driver takes requests from filesystem drivers and then sends the appropriate SCSI_REQUEST_BLOCK (SRB) to the Port driver. It is compatible with x86 and IA64 platforms.

P2P 之 UDP穿透NAT的原理与实现（附源代码） 原创：shootingstars 参考：http://midcom-p2p.sourceforge.net/draft-ford-midcom-p2p-01.txt baidu 论坛上经常有对P2P原理的讨论，但是讨论归讨论，很少有实质的东西产生（源代码）。呵呵，在这里我就用自己实现的一个源代码来说明UDP穿越NAT的原理。 首先先介绍一些基本概念： NAT(Network Address Translators)，网络地址转换：网络地址转换是在IP地址日益缺乏的情况下产生的，它的主要目的就是为了能够地址重用。NAT分为两大类，基本的NAT和NAPT(Network Address/Port Translator)。 最开始NAT是运行在路由器上的一个功能模块。 最先提出的是基本的NAT，它的产生基于如下事实：一个私有网络（域）中的节点中只有很少的节点需要与外网连接（呵呵，这是在上世纪90年代中期提出的）。那么这个子网中其实只有少数的节点需要全球唯一的IP地址，其他的节点的IP地址应该是可以重用的。 因此，基本的NAT实现的功能很简单，在子网内使用一个保留的IP子网段，这些IP对外是不可见的。子网内只有少数一些IP地址可以对应到真正全球唯一的IP地址。如果这些节点需要访问外部网络，那么基本NAT就负责将这个节点的子网内IP转化为

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.
