    I've been considering the idea of adopting the Freescale (a.k.a. Motorola)
    MPC870 processor for a board requiring ethernet, serial, USB (host and
    device), I2C and SPI connectivity, among other things. The processor would
    run FPGA-based signal processing hardware on the same board, handle
    configuration, firmware uploading and remote control/monitoring functions.

    One of the interesting things about this family of processors is that, I am
    told, they will run a version of Linux. This, to me, means that a huge body
    of work is already done and one can concentrate on application-specific
    code.

    The current version of the board has a Cygnal (whatever they are called now)
    8051 high-speed derivative. Implementing sophisticated connectivity is
    rather painful using this device. Here hardware cost is not as important as
    development speed and the ability to work at a higher level of abstraction.

    I'm looking for opinon as to the capabilities of these Freescale processors
    and, perhaps, suggestions for other devices I should be looking at.

    Thanks,
