Playstation 3 which is announced in May. Possibility in the business aspect (the efficiency of Cell understood with calls the world where it is actualized with the super powerful operational efficiency, anyhow, 2 tera- FLOPS over) considerably was shocking ones beforehand. Don't you think? this the game machine when the ぇ, with you say, unless Hisashi 夛 well the wood is the game machine, perhaps, you get angry but....... I do, really being to participate in concert, but Kousei detail the surprise was not felt excessively in graphics. But, when you call the reality of the movement, that is already another dimension from the present game mono. Therefore that simply graphics clean with the standard, イイ being something which cannot be measured, it does. Machine for the development of the PS3, because you make show, it could do, just a little just we would like to introduce.
Because the application, game interactive is the thing, a some behavior must be done according to some operation. But, the behavior was programmed so far beforehand. When it can point to behavior in the calculation, it is, but common sense of the natural world the fact that it becomes the movement which differs is the majority.
Don't you think? however in case of Cell, it can calculate all behavior thoroughly with all physical operations, it is. Here is funny. While not to be to use the technique that with シェーダプログラム that it seems and shows, developing the 3D model in Cell, doing also collision check and the like, it is the case that it can seek how form and motion change.For example the sail of the sailing ship how moving? When the bullet of the cannon hit there, whether some hole is less crowded, when the sail tears, when the wind hit, how び く? It moves entirely in the calculation. The eye which you saw is not enormous. Anyhow because it moves naturally, only it moves gulp down normally. So, there is enormous, don't you think? it is.
In case of PS3, Cell side is, developing geometry, making form decide, it can do collision processing and interactive processing. Anyhow because it is super high speed, with the operation it is not discouraged. The operational result remains as an enormous geometry data, but this it transfers to RSX which is GPU with Redwood of high-speed communication インターフェス. Doing tessellation and shading processing inside RSX, real it finishes in the picture. As for PS3 because bus width to be wide the ability of Cell is high, method of using CPU and GPU differs from PC rather, it is Cell side to, it is the case that it can be popular. So, the Cell. Whether in other things it is used with some use that, as for the programming model how having become? There is no tool which converts thread level in parallel simply? If the library is called, converting in parallel? 8 (in case of PS3 when 7) using SPE, as for each thread being allotted with some kind of method? There are various doubts, probably will be.
Because several among these is released to for the developer already, the authorized personnel thinks that you know. Speaking simply, from algorithm of the thread allotment which however it is not library level, by your shatter the mechanism which for the present shatters job in multithread operation finely in the thread, is 3 types one is selected, then the system appropriates SPE automatically.Still there is no meaning where everything understands at the level that, but when you see from the normal application programmer, however perhaps, it is visible troublesome to putting out performance, if the game house et. al. low level you see from the person who has been accustomed to programming, if the program of multithread operation is written at C language level, then it allots relatively simply, it seems a certain way, when (チƒ…ーン it does in ガリガリ, you exclude). When you rephrase, perhaps the notion that where even the sufficient extent, considerably it is room in the efficiency of Cell.
More the high performance which simply, in the society in the concert in E3, the real thing is different there is no demonstration red sandal wood with the machine? With it seems that the doubt which is said is applied. As for RSX which becomes the graphic tip/chip of PS3, the real thing has not done tape out yet, is, die. So, really from the point of view of the specifications of original PS3 using the machine for development of specifications which are inferior rather, it was moving, is true story. Furthermore, extremely part was excluded, the majority was moving with real time operation.
Machine for that development this photograph.Ps3 Cell of PS3 is the specifications of 3.2GHz, but as for being used with this development tool 2.4GHz version. Furthermore 00 where the clock is a little lower than the original specifications it is connected as GPU. 00 with the still unpublished tip/chip, bus interface is not Redwood and width of thing and the memory interface which become PCI Express just a little is different with, RSX most same.
By the way because PCI Express interface just has ridden in the one for test, there are only 4 lanes. With with the notion that where you say, the development tool clock frequency is low, (with simultaneously also the memory clock is low) on, means the machine which the connected band width of RSX is only 1 of several parts.
Therefore, the band width of Redwood is utilized, the ど っ - it is with sending the geometry which is formed with Cell to RSX when it is method of making the application such as rendering restriction is received in the performance aspect and, the normal using is it does not escape degradation, probably will be.
It correctly interprets that with with the notion that where you say, as for genuine PS3 the development machine which was used with demonstration compared to it becomes directly high performance っ て. If being certain, it does, the variety funny story to in addition to, but furthermore details have the opportunity, perhaps somewhere you write.
