Graph coloring is a highly e?ective approach to globalregister allocation. In this paper, we should study priority-based register allocation, whichis a e?

常用的寄存器分配算法是被稱作圖染色的寄存器分配算法日本乱子视频在线播放，本文所研究的基于優(yōu)先級的寄存器分配就是圖染色算法的一種。

There are several types of registers ,Including an instruction register , which holds the instruction being executed ,an address register, which holds the addresses of data to be processed ;a program register , which holds status information ; and an accumulator , which holds the results of the ALU's

Thus, an instruction that is updating a floating point register can be renamed along with an instruction that is updating a general purpose register or vector multimedia extensions instructions register using the same rename structure because the number of architected states for GPR is the same as the number of architected states for FPR and VR.

因此欧美性爱22k29.c0m，可以利用相同重命名結(jié)構(gòu)將正在更新浮點寄存器的指令與正在更新通用寄存器或矢量多媒體擴(kuò)展指令寄存器的指令一起重命名，因為用于GPR的架構(gòu)化狀態(tài)的數(shù)量與用于FPR和VR的架構(gòu)化狀態(tài)的數(shù)量相同在线免费观看黄色开车视频高清。

The general timing counter applied in computer includes configuration register TCCFG control word register TCCON, state register TCSTA, initial value register TCPAL and internal counter TCCOUNTER. Both the said internal counter TCCOUNTER and the internal bus are in 32 bit width and the 32 bit read-out bus and 32 bit write-in bus are connected directly to the 32 bit internal bus. Therefore, the present invention has the advantages of long counting time, high precision and simple chip design and programming.

In general,the code optimization and code-generation phases of a compiler,often referred to as the back end,may take multiple passes over the IR before generating the targer program.

如果需要使用一個寄存器但是這個寄存器存放其他變量，那么需要產(chǎn)生ST R国产一级A爱片在线视频，M來釋放這個寄存器色色色鬼，這個過程稱為register spill寄存器溢出

The paper detailedly introduces two methods of the regiseter renaming in X high-performance microprocessor, respectively implemented through register rotation and register stack, give an example to show how software pipelining supported by register rotation overcomes the disadvantage to code optimization induced by traditional unloop method, and furthermore implements the renaming design of general register, floating point register and predication register.

For example, if a register isconnected to the data bus in an 8-bit machine. eachline of the bus connects to register.Because the databus will be an 8一bit bus, there are 8-bit Flip-flopsthat form the register, When there is information onthe data bus,and a particular register is selected toreceive data, all the Flip-flops will store data simultancously. This kind of register is refer is referred to as aparallel register.

例如性刺激的欧美三级视频中文第一页，如果寄存器被聯(lián)接到一臺8位機(jī)的數(shù)據(jù)總線上，那么黄色网站啊啊是视频在线免费看，該總線的每一條線均聯(lián)接到寄存器上天天操天天怕天天日天天，因為數(shù)據(jù)總線是8位總線，所以有9個觸發(fā)器來形成寄存器一级爱爱视频免费观看，當(dāng)在數(shù)據(jù)總線上有信息，并且選擇了一個特定的寄存器來接收數(shù)據(jù)時免费观看黄A级毛片，那么所有的觸發(fā)器將同時存儲數(shù)據(jù)，這種形式的寄存器叫做&并行寄存器&欧美老妇肥婆毛多水多性强。

In the past research, instruction clustering pay more attension on instruction parallelism, and pass the register pressure to register allocator. In this paper, the authors clustered instruction through runtime inspection of the register command pressure.

在以往的研究中，軟件流水之前的指令分簇會更多地考慮指令并行性啦啦啦资源在线完整免费高清观看3，往往會把寄存器的壓力交給寄存器分配階段，當(dāng)物理寄存器不夠分配時會造成寄存器溢出人人操在线精品。
