说明：  设计相应的数字逻辑判断以下几种情况： a）确定一个32-bit有符号数大于零 b）确定一个32-bit有符号数小于零 c）确定两个32-bit有符号数相等 d）确定两个32-bit有符号数不相等 e）比较两个32-bit有符号数的大小 画出电路框图，分析复杂度和成本，探讨MIPS指令集分支转移指令的条件比较在硬件实现上可能的优势。(Design corresponding digital logic to judge the following situations: a) Determine that a 32-bit signed number is greater than zero b) Make sure that a 32-bit signed number is less than zero c) Make sure two 32-bit signed numbers are equal d) Make sure the two 32-bit signed numbers are not equal e) Compare the size of two 32-bit signed numbers Draw the circuit diagram, analyze the complexity and cost, and discuss the possible advantages of MIPS instruction set branch transfer instruction in hardware implementation.)

说明：  永磁同步电机电机pid控制的一种前馈控制法，解耦控制，(A feedforward control method for PID control of permanent magnet synchronous motor, decoupling control)

固定虚警概率Pf，检测概率Pd随着SNR的的变化。(Fixed false alarm probability Pf, detection probability Pd changes with SNR.)

通过计算方差，确定划分坐标轴，最后，将点云划分到一个个格子中，这样的好处在于可以将噪点和有效点分别存储于不同的格子中，方便进行去噪。(k-d tree create;By calculating the variance, the coordinate axis is determined. Finally, the point cloud is divided into a number of lattices. The advantage is that the noise and the effective points can be stored in the different lattice, so that the noise can be de-noised conveniently.)
