Il processore Cell è basato su un sistema di tipo system on a Chip (SoC)?
Qui viene riportato un articolo di cui ne parla. Riporto la parte inerente:
The basic architecture of the Cell is described by IBM as a "system on a chip" (SoC) design. This is a perfectly good characterization, but I'd take it even further and call Cell a "network on a chip." As I described yesterday, the Cell's eight SPUs are essentially full-blown vector "computers," insofar as they are fairly simple CPUs with their own local storage.
These small vector computers are connected to each other and to the 512KB L2 cache via a element interface bus (EIB) that consists of four sixteen-byte data rings with 64-bit tags. This bus can transfer 96 bytes/cycle, and can handle over 100 outstanding requests.
Qualche delucidazione? :D
