Allegorically the inner memory is the"big storehouse"of the CPU data processing, all the instructions and data processed by CPU must be transferred by inner memory to the other parts of computer system.

内存可以说是CPU处理数据的&大仓库&，所有经过CPU处理的指令和数据都要经过内存传递到电脑其他配件上，因此内存性能的好坏，直接影响到系统的稳定性和运行性能。

A better algorithm and corresponding real time implementation scheme are proposed. By methodic arranging the clocks of CPU and AD/DA, the scheme can not only scale the pitch in two octave range effectively, but also process the real time input audio for synchronous scaling output. The experimental results on Windows platform indicate the modest CPU and memory consumption, so as to meet the requirement of real time applications.

改造后的实时变调算法与实现方案通过合理控制CPU时钟和AD/DA时钟的时序关系，不仅能够在两个八度音范围内进行有效的变调，而且能够对实时输入的音频信号进行同步变调输出，在Windows平台上验证实验还表明新方案具有较低的CPU占用率和内存消耗，能够满足实时应用的要求。

Some programs may wish to bind a KSE (pedantically speaking, a KSEG is bound) to a particular processor in order to improve cache locality, or to tighten the bounds on a real-time task. Bound KSEs are run only on one CPU, unless priority inheritance forces it to be run on another CPU in order to avoid deadlock due to priority inversion.

一些程序可能希望把KSE绑定在一个单独的CPU上来提高缓存的击中率，或是让实时任务更严密，被绑定的KSE只运行在一个CPU上，除非在优先级倒置时，为了避免死锁，优先级继承迫使它运行在另一个CPU上。

We should pay attention to the removal or installation to maintain the balance of CPU, in particular, attention should be paid prior to installation to check whether the pin-bending, do not always make a beat or out, or else it may break pin CPU.

平时使时，我们不应忽视对CPU风扇的保养，比如在气温较低的情况下，风扇的润滑油容易失败，导致运行噪音大，甚至风扇坏掉，这时我们就应该将风扇拆下清理并加油。

The system adopts CPU board with fast processing elevator operational program, data signal exchange, and HMI screen, which can make sure reliable operation and high speed. It also has PHILIPS SJA1000T field CAN bus, 82C251 Bus interface and the latest serial storage technique to record data. The functions of external watchdog and control chip internal watchdog compose two-level procedure monitoring, so as to ensure the normal operation of the control program. Heavy-current switch power LM2576 ensures the stable system working power, which has low requirements for the power supply. High-speed optoelectronic isolator and internal frequency division technology can make NW3P08-41C (42C) CPU receive the input impulse up to 1-phase 100 KHZ*2 CHANEL or 2-phase 50KHZ*1 CHANEL 32bit.
