之后，是两个加法指令，第一个是普通相加，第二个是带进位相加。
Then comes two add instructions. The first is a normal add and the second one is add with carry.
因此，si_a (a,b)会强制使用a指令做加法运算。
So, si_a (a, b) forces the instruction a to be used for addition.
可以看到test1()中每次加法都需要读取和存储全局变量errs，而在test2()中，localerrs分配在寄存器上，只需要一条指令。
Note that test1 must load and store the global errs value each time it is incremented, whereas test2 stores localerrs in a register and needs only a single instruction.
然而，如果传递两个vectorfloat作为参数，就会生成fa(浮点加法)指令。
However, if given two vector floats as parameters, it will generate the fa (float add) instruction.
另外，当 spu_add 被传递两个vectorunsignedint作为参数时，就会生成一条 a（32 位加法）指令。
For addition, spu_add, when given two vector unsigned ints as parameters, will generate the a (32-bit add) instruction.
对先前的扣押和起诉处罚，增加法院指令的救济。
Adding the remedy of court injunctions to the previous penalties of seizures and prosecutions.
举例来说，spu_add (myvec,2)就会生成一条ai(立即加法)指令，而spu_add (myvec, 2000)则首先会使用il将2000加载到自己的向量中，然后执行a(加法)指令。
For instance, spu_add (myvec, 2) generates an ai (add immediate) instruction, while spu_add (myvec, 2000) first loads the 2000 into its own vector using il and then performs the a (add) instruction.
浮点加法器是协处理器的核心运算部件，是实现浮点指令各种运算的基础，其设计优化是提高浮点运算速度和精度的关键途径。
High-Speed Floating-point Adder is a critical part in the coprocessor, which is attached to the computing basis of floating-point instructions.
加法器将指令移动量与各补偿移动量相加以驱动各马达。
Adders add up the command motion amounts and the respective compensation motion amounts to drive respective motors.
