LDPC码编码器FPGA实现研究

成为编码硬件实现的一个障碍;论文针对实际系统的预期指标,通过对多种矩阵构造算法的预选方案及影响LDPC码性能参数仿真分析,基于1/2码率,1024和2048两种帧长,设计了三种编码器的备选方案,分别为直接下三角编码器,串行准循环编码器和二阶准循环编码器

银行家算法。多个进程动态地共享系统的资源可能会产生死锁现象。死锁的产生

即一个资源每次只能由一个进程占用;第二个为请求和保持条件,即一个进程请求资源不能满足时,它必须等待,但它仍继续保持已得到的所有其它资源;第三个是不剥夺条件,任何一个进程不能抢占另一个进程已经获得且未释放的资源;第四个为循环等待条件

聚类算法:k—medoids 方法。这儿选取一个对象叫做mediod来代替上面的中心 的作用

以下是循环的: 2,将余下的对象分到各个类中去(根据与medoid最相近的原则); 3,对于每个类(Oi)中,顺序选取一个Or,计算用Or代替Oi后的消耗—E(Or)。选择E最小的那个Or来代替Oi。

该程序在显示三角形时的顺序是从顶点到底边,首先得定位顶点像素的坐行列坐标(dx,cx)则接其后的像素起始坐标为(dx+1,cx-1),终点坐标为(dx+1,cx+1),再接着的下一行像素的起始坐标为(

再下一行始终点坐标分别为(dx+3,cx-3),(dx+3,cx+3).依此类推直到最后一行的始终坐标分别为(dx+n,cx-n),(dx+n,cx+n).在写同行像素时用cmp cx,cx+n jnz Y 来实现循环
