Some more thoughts to consider.
Has the Engineering Group considered ARM processors?
These are the industry defacto standard for embedded processors and come
in a wide variety of flavors. They are also supported by every RTOS
vendor and there is a large body of RT Linux products available (i.e.
cheap
OS)
Several devices run at 210 MIPS which should easily handle correlator
duties.
I just grabbed a spec sheet from NetSilicon for their NET+ARM system on
a
chip.
It has a 10/100 Eithernet MAC, P1284, dual serial (SPI, UART, HDLC),
10-channel DMA
Dual timers, watchdogs, 40 GPIO and 16 GPI pins, etc.
