Me l'ha portata un amico che tornava da Hong Kong
Si la mia psp è perfetta, ho gia provato ad inserire mp3 e filmati video mpg4, senza alcun problema.
Io invece mi sono fatto prendere Ridge Racers

- Clock frequency was not 333MHz but 222MHz.

In fact, the PSP chip was operating only with two thirds of the clocks of spec. The present PSP cannot still demonstrate full performance. Moreover, OS kernel of PSP occupied no less than 8MB of area among 32MB of main memory. This is large to an exception as OS kernel area of a game machine.

In "GDC (Game Developers Conference)" held in mid-March, the side seldom generally known about PSP until now was clarified. SCEA (Sony Computer Entertainment America) performed the session entitled "PSP Advanced Software Overview" by GDC. In it, Mr. Mark DeLoura (Manager of Developer Relations) of SCEA explained the software layer and the whole tool image to be updates of PSP hardware spec.

By old official announcement, the frequency of the core based CPU of PSP of operation is KONFIGYURABURU, and must have operated by a maximum of 333MHz. However, by GDC, the core based CPU of PSP was explained that the present condition is restrained by 222MHz. It will be exactly stopped by two thirds of the clocks of spec. Moreover, bus speed is also retreating from 166MHz at the time of the spec. announcement of the year before last (from a zone to an inverse operation) to a maximum of 111MHz.

"Although CPU has a range to 333MHz, it is locked by 222MHz in the present condition. Since a bus is the half (clock) of CPU typically, it is 111MHz. When it determines to pull up CPU to 333MHz, Mr. DeLoura explains that a bus will also be pulled up to 166MHz."

A 222MHz down grade is provisional specification, and has suggested that it may pull up to 333MHz in the future. From now on, improvement may be made possible to 333MHz in the stage in which it shifted to 65nm process or the manufacture process after it, and power consumption fell.

SCEA did not explain finely the reason restricted to 222MHz. However, the reduction in frequency of be [ it / a sake ] of electric power reduction is clear so that it may understand also from this specification change being explained at the corner of power saving. PSP is the 222MHz present condition and is a line last-minute [ using the lithium ion battery of 1,800mAh comfortably ] as operation of 4 - 6 hours, and a game machine. Therefore, CPU frequency is raised more than this, power consumption is increased, and it is surmised that battery drive time was not able to be deleted. The actual solution in the present semiconductor technology seemed to be not 333MHz but 222MHz.







- Power consumption reduction which is PSP with many difficulties

I hear that, as for the Ming kana, SCEI is also taking pains over power consumption reduction from the frequency lock of PSP. It is not only TDP (Thermal Design Power:heat design power consumption) but average power consumption especially to become a problem in PSP. since leak (leak) current is large and average power consumption is echoed -- the present detailed-izing -- it is very difficult to reduce in a process the bottom It is one of the future technical hurdles of PSP which can cut down leak electric power by improvement of process technology, circuitry, etc.

It seems that but devices other than a main chip set will consume electric power rather if the whole PSP is seen. It was explained by explanation by GDC that a high luminosity setup of seeking of a UMD drive, wireless LAN (Wi-Fi), and a liquid crystal display etc. was the operation which consumes electric power very much. On the contrary, it is said that there is little power consumption as for media engine, a bus, and a memory stick.

Since media engine including AVC decoding is considerably made hard-wired, it has little power consumption. By the HotChips conference in August, 2004, the average power consumption at the time of AVC decoding was explained to be 500mW or less. It is concluded that a bus is because power-saving is possible in turning off briskly.

As for PSP, power-saving of a UMD drive, a wireless LAN module, etc. will also be needed from now on. It was appealing in GDC to suppress access to UMD. Moreover, it will become an important element as the wireless LAN correspondence title of power-saving of a wireless LAN module increases.

A 222MHz lock has a certain amount of influence also on software development. For example, when the frequency to 333MHz can be used and the high software of the load using a full CPU clock is made, the case where it is incompatible with the 222MHz present model on a problem may come out. However, when it sees positively, PSP will have room to still raise performance in spec.





- 8MB and huge OS kernel area

The outline was explained also about OS of PSP by GDC. But big subject was that OS kernel occupies 8MB. OS kernel of a game machine has many hundreds of KB units and very thin things, and it is very exceptional to secure the quantity of no less than 8MB. Only 24MB will be left behind to the user (game developer) among 32MB of main memories of PSP.

The thing with a large kernel occupancy memory is for control of various functions PSP. Since PSP has taken the programming model of an API base fundamentally (however, the graphics register list etc. is exhibited), the rate of a library layer or a driver is relatively conjectured to be large. It is reason that a part with the high degree of abstraction of hardware and a software layer become thick.

Various OS kernel modules and a low level driver are loaded to 8MB space, and it is the utility of PSP. An applet also runs. Engine, such as a network, an audio, and movie reproduction, is also contained in a module. There are save data management, a network configuration, an ounce clean keyboard, various message dialogs, etc. in an applet.

That is, it is said that it was set to 8MB as a result of the kernel main part of PSP necessarily not having the size of 8MB and also securing space, such as various engine, and a protocol stack, an applet. Securing the space of an applet has in a game the advantage that it can change quickly at an applet, running a game program.

- The main memory of PSP which was 8MB from the first

It is interesting that the quantity of the main memory of PSP which SCEI was planning at the beginning was 8MB in 8MB of OS kernel area. That is, if a lid is opened, the amount of main memories of a plan from the first will have been used up only by OS kernel by the side of SCEI. When SCEI has advanced PSP by the spec. of 8MB memory as planned [ original ], a possibility that OS development by the side of SCEI also became very difficult is high.

About the main memory of PSP, it is the stage of the last pickpocket ‚_‚킹 of the spec. of PSP, and it is said that there was remarkable çaç€. The opinion collided with SCEI to hold down from the standpoint of semiconductor manufacture to 8MB by eDRAM (inclusion DRAM) ONRI among game developers needed in the amount of memories of PS2 class from the standpoint of game development. Finally, the SCEI side hears the opinion about the desirable amount of memories to a game developer side. Since there were many opinions of 32MB overwhelmingly, there are circumstances where made the DDR memory of 256Mbit external and 32MB main memory was realized.

The game developer side desired 32MB, because he wanted to make easy the transplant from PS2 of 32MB memory. But, since OS kernel occupies 8MB in fact, a memory cannot be used like PS2 which was able to use 32MB almost free. But in PS2, since a certain grade is in the OS side as for the module which had to be prepared by the developer side, its memory required quantity decreases depending on [ PS /2 ] software.

The affair of the amount of memories of PSP showing is that the hardware design of SCEI may not link well with development of the software architecture. If the software architect is closely concerned in the stage of a hard design, it will be surmised that there were probably no many complications in the amount of memories. If the abstraction by software is thickened, the amount of memories is more mostly needed.

It is the weak point of SCEI that this disagreement of a as soft design as hard is seen by the way. Especially the software architect side serves as a big difference from Microsoft which determines hard specification. But the device development itself which used independent semiconductor technology of SCEI as the base is a big strong point. If there is no it, it is difficult to make a game machine like PSP.

- With [ a UMD game ] no region code

The profile of UMD and the file format were also explained by GDC. UMD has three kinds of profiles, a PSP game, UMD Audio, and UMD Video, in the present condition. Among these, a region code is not set up about a PSP game. However, an audio and video are likely to be restrained.

In GDC, the outline was clarified also with "VFPU (vector floating point arithmetic unit)" of the core based CPU of PSP. The core based CPU of PSP is R4000 system core of a MIPS32 system command set, and VFPU is attached as an extended operation unit. VFPU is designed a vector and for matrix operations and supports a 32-bit single accuracy floating decimal point format of IEEE 754. The �Ϙa operation of the matrix/vector of 4x4 serves as 22 cycle latency.

VFPU is equipped with 128 KONFIGYURABURU 32-bit registers, and a vector and not only a matrix but the Scala operation is possible for it. It is expected at the time of a vector and a matrix that two or more registers are combined. Moreover, the floating decimal point data of 32 / 16/8-bit integer, and half size can also be treated. That is, PSP is comparatively powerful and is stacking high VFPU of flexibility.

[Simon82]

Da quello che si capisce, al momento la PSP ha le risorse sottodimensionate per un problema (si crede) di consumi delle batterie. La cpu e' a 222mhz abbassando il bus della stessa di un terzo e addirittura anche la memoria sembra avere un tetto di utilizzo di 8Mb. Sembra che in futuro quando passeranno ad un processo di costruzione dei chip di .65nm, potranno sbloccare le ulteriori potenzialita' della console in una probabile nuova versione di PSP.
C'e' da chiedersi se quando usciranno giochi sviluppati per utilizzare le risorse "piene" della PSP, questi saranno compatibili con la versione attuale "castrata"?

Tetto di 8 Mb?A me sembra di aver capito che il sistema operativo di PSP occupa 8 Mb di memoria (che mi sembra moolto esagerato...) e che il totale è di 32Mb,contro gli 8Mb annunciati in un primo tempo.....

X la CPU e future versioni di PSP,non pendo che Sony butterà fuori una versione di PSP + potente...sarebbe veramente un tradimento x chi l'ha già acquistata.....ed ovv un gioco disegnato x girare con piena potenza di calcolo su una PSP@2/3 non può che scattare....
Spero che la frequenza di clock x gli sfigati che avranno già la PSP (come me) sarà sbloccabile con un aggiornamento sw....anke se nn penso sarà così semplice...
