条件指令

Branch instruction has serious effect on the performance of superscalar microprocessor.

转移指令，特别是条件转移指令是影响超标县处理器性能的关键。

This will lead the recursive traversal algorithm to follow both the paths, the instruction immediately after the conditional jump instruction and the target of the jump instruction, potentially leading to an inconsistent state.

它将引导递归遍历算法跟随这两个路径：条件跳转指令之后紧接的那条指令和跳转指令的目标，潜在地导致一个不相容的状态。

Because SBB is going to set EAX either to zero or to 0xffffffff, we can consider the following AND instruction to be similar to a conditional assignment instruction (much like the CMOV instruction discussed later).

我们先从"与"指令说起，因为根据减法的结果，SBB将eax寄存器设为全F或全0，我们可以推出逻辑"与"的结果等价与一个条件赋值语句(类似于我们后面会讨论的CMOV指令)。

The recursive traversal method can be fooled by placing garbage data after a conditional jump instruction and programmatically ensuring that the jump condition always succeeds.

通过在一个有条件跳转指令之后放置无用数据、并且有规划地确保跳转条件总是跳转成功，能够欺骗递归遍历方法。

The third instruction would be a conditional jump going back to the start of the loop.

第三条指令，将是一个依条件判定是否跳转回循环中的第一条指令。

Similarly, people complain that when they issue conditional jumps that try to jump too far, NASM reports 'short jump out of range' instead of making the jumps longer.

同样，人们经常抱怨说在他们使用条件跳转指令时(这些指令缺省状况下是short的)经常需要跳转比较远，而NASM会报告说short jump out of range，而不作长远转。

In comparison, the Core CPU can perform 4 DP FLOPS/cycle and then some: a 128 bit multiply, a 128 bit add, a 128 bit load, a 128 bit store and then perhaps an ALU or fused compare and jump instruction in the last dispatch port.

Core可以在一个周期内完成4个双精度浮点操作以及其他一些指令，具体地说就是：一个128bit浮点乘法，一个128bit浮点加法，一个128bit的内存读取，一个128bit的内存写入，或许还有一个ALU指令或者一个Macro-ops融合之后的比较条件跳转指令。

In this paper, we analyzed the performance limitation of Two Level Adaptive Branch Prediction via trace simulatingtwo benchmark program.

并指出，多条件码和条件式执行技术与转移预测相结合，可减少条件转移指令和误预测率，提高处理器的性能。

The former can be used to make the instructions in advance according to the information of the production tasks of electric arc furnaces and this convertor, which is suitable to the producing conditions of being short of on-line testing equipments, the later can correct the operating parameters according to the information of on-line testing equipments in the process of blowing The results of computer imitating and on-the-spot debugging make clear that the ratio of cold material and the rate of negotiable metal recovery will be improved a lot if we operate convertors in accordance with the computer instructions made by the software system.

前者可根据矿热电炉生产任务安排和本炉吹炼任务等信息预排操作指令表，用于目前无在线检测设备的生产条件；后者可在操作过程中根据在线检测信息修正相关操作参数。计算机仿真及现场调试结果表明：按照该软件系统产生的指令进行操作，可使冷料率、有价金属回收率等生产指标得到明显的提高。

Article 34 If the trading results are not in accordance with the instructions of the investor, or the forced closing out of positions is not in accordance with the legal or agreed conditions, where the futures brokerage company is at fault, it shall re-execute the instructions of the investor or restore the positions forcibly closed out within the period agreed upon in the contract of futures brokerage, and shall compensate for the direct losses incurred therefrom.

第三十四条交易结果不符合投资者交易指令，或者强行平仓不符合法定或者约定条件，期货经纪公司有过错的，应当在期货经纪合同约定的时间内重新执行投资者交易指令或者恢复被强行平仓的头寸，并赔偿由此产生的直接损失。
