-SCCB protocol and I2C protocol differences
SCCB is to simplify the I2C protocol, SIO-l is the serial clock input line, SIO-O is a bidirectional serial data line, respectively, equivalent to the I2C protocol SCL and SDA. SCCB and I2C bus timing is basically the same, the response signal ACK is called a transmission unit of the first nine, divided into Don t care and NA. Don t care bits generated by the slave NA bits generated by the master, the SCCB does not support multi-byte read and write, NA bit must be high. In addition, SCCB did not repeat the initial concept, so the SCCB read cycle, when the host sending the on-chip register address, you must send a bus stop conditions. Otherwise, send the read command, the slave will not respond to signals generated Don t care.
SCCB as I2C and some nuances, so the use of GPIO analog SCCB bus way. SCL pin is always connected to the output mode is set, and the SDA pin is connected to the data transfer process, by setting the value of IODIR Platform: |

Description: 模拟两级复制算法，引入了将系统进行分级的思想。该算法充分考虑了典型的移动计算环境中可信部分和移动部分的性能差异，将整个移动计算环境分为两级，第一级是通过固定网络保持连接的基结点，每个基结点维护数据库的一个副本，且这个基结点是大部分数据对象的结点，此级复制是基结点之间的复制。第二级为时常处于断连状态的移动结点，它们有时候通过无线网络与基结点相连接，有时处于断接状态，也存有数据库的部分副本，此级复制是指移动结点与基结点之间的复制。这样，可信部分总能保持传统分布计算环境下的若干特征，而不会因为移动计算的引入对系统性能产生不良的影响。
两级复制机制的主要研究目的在于保证所有结点的数据在经过一些临时状态的改变后能够趋于一致。

The algorithm takes into account the typical mobile computing environments trusted part of the performance differences and moving parts, the entire mobile computing environment is divided into two stages, the first stage is the base nodes remain connected via the fixed network, each base node maintain a copy of the , and the group node is the node most of the data object, this base-level replication is replicated between nodes. The second level is often in a state of disconnection mobile nodes, they are sometimes connected through a wireless network to the base node, sometimes in a disconnected state, there are also part of the copy of the , this level refers to the mobile node replication and Copy groups between nodes. Thus, to maintain a credible part of the total number of feature traditional distributed computing environment, and not because of the introduction of mobile computing adverse effect on system p Platform: |
