摘要：parity testing is one of the compact testing techniques, which, traditionally, relies on applying all 2^n input combinations to an n-input combinational circuit without need of knowing the implementation of the circuits under test. The faults can be detected just by observing and comparing its parity of whole output of circuit with the expectation one. The way seemed to be less interesting to the test eagineers in the past days, mainly due to the reasons of its exhaustive testing and time-cousuming, which became a barrier as the number of input lines gets growing. However its great facility and convenience in testing still interest to the engineers who need to have a quick look at the qualities of the circuits without generating the test patterns for a given circuit to be tested. In this paper, a new approach called pseudo-parity testing is presented to deal with the dilemma we are facing： i. e. to change an exhaustive parity testing into a non-exhaustive one, followed by a pseudo- parity testable design to help realize the new way of pseudo-parity testing. The idea of pseudo-parity testing presented in this paper may resume its spirits towards its promising future.

摘要：本文提出了适用于IEEE 802.11ac标准草案LDPC码编码器的设计方案。设计方案针对LDPC码的校验矩阵的准循环、双对角线的结构特点,采用了具有低复杂度的快速迭代算法,在FreeScale公司的MSC8156 DSP平台上实现了LDPC码的编码器,并对代码进行了合理的优化。测试结果显示,使用MSC8156的一个运算核心进行编码的平均速率可达1Gbps以上,满足系统要求。

摘要：数据收转发是指数据的接收和发送。在接收数据时要进行两次握手信号,第一次握手信号确定网络是否忙,网络空闲时发出第二个握手信号告之端口开始传输数据,网络忙则发出暂停接收信号。在发送数据时,也要进行两次握手信号,第一次握手信号确定网络是否忙,网络空闲时发出第二个握手信号告之端口开始输出数据。当要向本端口发送数据时,首先要发出一个握手信号,如果此时空闲才接收,如果忙则告诉对方暂停接收,同时告诉协议转换部分接收数据。
