I have a technical question...
 Some time ago, I have read that no all SPE from the Cell do the same.
That there are specialized SPE, and I'm not referring to the PPE.

I been reading and searching for this issue, on the net this, two past
days, but I been unable to found accurate information.

All I have found, talks about the EBI o BIE, well, the bus connecting
the SPEs, Ram and so on, but the documents I have found, manage as a 7+1
 architecture, like if all SPE are equal.

Also, I'm not sure, dees SPE support Altivec?.

I used the PPC architecture since 603e, and was a proudly owner of a G3
Macbook with Yellowdog... But have been out of circulation for about 2
years... and I'm returning to ppc, and I found this new, hum, hem,
well.. I found the cell...

Also I have read that the SPE and the PPE execute in order instructions,
is this true? There is no out of order execution, branch prediction? Or
the PPE issue the instrucction to the SPE, and the SPE compute, not
caring what kind of instruction is issued?

Thanks!
