Dave McGuire wrote about the HSC50:
I knew there was an F11
in there, and I always wondered HOW THE HELL they got that kind of
performance on all of those channels, shooting all that data around,
with just an F11 (at, what, ~14MHz?) chugging away under the hood.
Yes, the F11 (or
J11 in newer HSCs) never even sees the actual data.
That's all done by the bit slice processors and other dedicated hardware.
