Hello,

I have been trying to find out what does the word 'broadband'
indicates in the name of the processor 'cell broadband engine'. Is it
because of the fact that the processor has prioritized digital
bandwidth over latency?

Perhaps partly. But it was also originally intended for use in
advanced video games (the Playstation 3) so it was intended to be used
for graphics processing - so it is intended for applications requiring
high computational bandwidth.

Thanks John. Initially I guessed the same too i.e. computational
bandwidth. But I have also been reading that the word pertains to
"memory bandwidth". Do you have any idea what does that mean here?

A plausible answer, along with considerable discussion, is given in
the thread on Larrabee, a device that has some similarities, including
probably purpose, to the "Broadband Engine." One target application
for both devices is multimedia content delivered via the Internet.

Thanks Robert. I went through the Larrabee threads (particularly this
one:
http://groups.google.com/group/comp.arch/browse_thread/thread/adc41f41e535c569/6d03228e0e4b34bb?hl=en&lnk=gst&q=larrabee#6d03228e0e4b34bb)
where they talk about the memory bandwidths. The explanation appears
plausible but I am still wondering if that is the official explanation
of the term "broadband" in CBE. I could not find similar information
on IBM page.
