Peter: Dual port ram would be sweet, too involved for me, however. Imagine soldering those tiny wires onto the DSP, 16 address lines + 24 data lines. It would be easier to reproduce a DSP board to sit on the expansion connector.
Earx: Thanx for understanding my idea. Yes, simply buffer the host transfers so the main cpu isn't tied down with wait states (polling or not, access to the host port is much slower than st-ram).
16bit host transfer would allow twice as much bandwidth. That would be nice but I still don't think it solves the problem. 8mb/s vs. ~100mb/s for CT60 access to fast-ram. Also, there are only 8 host data lines present on the 56001 so we're stuck unless we replace the DSP.

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
