Now then, about those PS3 games on your PSP...


Sony's head of hardware development for both the PS3 and the PSP, Izumi Kawanishi, sat down with Famitsu magazine to discuss the details of the plaguing question: what's with the connectivity between the PS3 and the PSP... game-wise? Clearly, just viewing the media wouldn't be enough, so... there's got to be more to it than that. Says IGN: "While Kawanishi didn't get into specifics, we imagine the PSP being used just to display game footage sent to it by the PS3 and send back controller data input by the player." Yeah, well, if that isn't a revelation, here's a bit of foresight: Kawanishi purposely created the PSP with a 16:9 display because he had this idea for the future in mind. Good job, Izumi-chan. Can we say that? Of course, you need the 60GB Wi-Fi model of the PS3 to take advantage of this connectivity. Kawanishi didn't really go into whether a USB Wi-Fi connection with the lower-end model will yield the same result, but really, why wouldn't it?

In a similar but mostly unrelated vein, updating your system software will be done via flash media or game/media software -- similar to the PSP system updates. Kawanishi made mention also that the PS3 games will indeed be region-free, so they can be played as-is (although there will be "exceptions"...). So there you have it -- a few questions answered, a couple left. Any plaguing you in particular? We'll keep an eye out for certain ones that pop up often.

The PS3's 3.2 GHz Cell processor, developed jointly by Sony, Toshiba and IBM ("SIT"), is an implementation to dynamically assign physical processor cores to do different types of work independantly. It has a PowerPC-based "Power Processing Element" (PPE) and six accessible 3.2 GHz Synergistic Processing Elements (SPEs), a seventh runs in a special mode and is dedicated to OS security, and an eighth disabled to improve production yields. The PPE, SPE's and other elements ("units") are connected via an Element Interconnect Bus which serves to connect all of the units in a ring-style bus. The PPE has a 512KB level 2 cache and one VMX vector unit. Each of the SPEs is a RISC processor with 128 128-bit SIMD GPRs and superscalar functions. Each SPE contains 256KB of non-cached memory (local storage, "LS") that is shared by program code and work data. SPEs may access more data in the main memory using DMA. The floating point performance of the whole system (CPU + GPU) is reported to be 2.18 TFLOPS[38]. PlayStation 3's Cell CPU achieves 218 GFLOPS single precision float and is reported at around 26 GFLOPS double precision. The PS3 will ship with 256 MB of Rambus XDR DRAM, clocked at CPU die speed.
