You just don't seem to understand.  14K is the flashing rate in bytes
per second and has nothing to do with your "1M rate" which is bits per
second on TDI/TDO and clocking the JTAG state machine  If I told you
that the CrossConnect actually runs a 4MHz clock on TCK that's faster
than your 1M rate isn't it?

You're comparing apples with oranges.  Until you can understand that we
can write data into RAM at 200Kbytes/second (that equates to
1.6Mbit/second), you're just not going to grasp that these pieces of
hardware are comparible and, as far as I can tell form what you've said,
the CrossConnect is faster.
