编码器

In this paper, we present a register allocation and assignment algorithm based on graph coloring, which uses a heuristic model to find out which virtual variables in program should be assigned into the set of registers accessible by shorter instructions.

在这篇论文中，我们提出了两个基於著色演算法的暂存器配置与分派演算法，它们使用一个估计的方法去找出适合被指派到短指令格式能存取到之暂存器的程式变数，而适合的变数意味著如果指派它们到这些暂存器可以有效增加可以被编码成短指令的指令数量。

In this advanced architecture of QC-LDPC codes encoder, the RAM is advisably used to store the parity-check bits and the pointers are introduced as the addresses of the RAM instead of shift registers used for storing the generator of H. Thus, the encoding; process can be achieved by reading and writing on RAM and the parity-cheek bits can be output serially.

采用RAM存储校验位，并引入指针来指示RAM的地址方法，从而取代传统编码架构中的移位寄存器，使编码过程通过对RAM的读写操作实现，校验位序列也通过对RAM的读操作串行输出。

The biconditional markers placed on the rail track are detected sequentially by the on-board reader, and checked by the feedback logic function of generating absolute position encoding sequence.

当列车在线路上运行时，通过车载阅读器顺序检测二值标记，在移位存储器中构成绝对位置编码值，利用生成绝对位置编码序列的反馈逻辑函数进行容错处理，输出定位信息。

The biconditional markers placed on the rail track are detected sequentially by the on-board reader, and checked by the feedback logic function of generating absolute position encoding sequence. The exclusive position code consists of the binary information in the shift register.

The simulation results show that the difference between actually picture coded bits and picture target bits can be minimized by monitoring the "virtual buffer" state to adjust the quantization scaling factor, and thus more stable picture quality can be achieved at a fixed rate.

结果表明，码率控制通过监视"虚拟缓存器"状态调节量化尺度因子，能保持实际帧编码比特数与预分配帧编码比特数一致，从而在恒定码率下，获得均匀的图像质量。

In part one (chapter 2-3), two new methods and systems of optical parallel logic operation are studied. Triple-in Double-out shadow-casting logic operation system is proposed and realized for the first time. Based on this, optical full adder and 3-bit decoder array logic have been obtained. It is the first time to use coding pattern and different reading-writing model to realize BSO-PROM optical parallel logic operation where the time-order operation is avoided, so that the computing speed of optical parallel logic gate which uses this kind of spatial light modulator is increased, and it is successfully used in optical symbolic substitution .
