Let's say I want to build come computer-based device, OK, and let's
say I want to interface this to an IBM-PC, OK. I want that the
PC could be able to download into the memory of this project,
and then kick the processor to start executing.

Holding and starting the processor via PC control is no problem.
My question is, what is the best way to facilitate the PC-downloading
of the other CPU's memory?

I know some chips, like t he AT&T WEDSP32C, have a mode in which you
can send addresses and data to the parallel ports of the CPU, and
that data will go to the memory of the processor at the requested
address. This is, needless to say, _quite_ handy.

I have seen some chips called "dual-ported something-or-other", but
have not investigated. Are they usable (and simple) solutions?

Thanks for your replies.
