It just dawned on me that I had once used this exact method for a similar application...on an i860 chip.
Gawd, I feel old.

Aha, a "memrefin" example - I'd been getting curious about those ever since you first mentioned them! Thanks!

I've made a couple of mods to my wave-scan dem and updated the original post, v2. Nothing serious; I spotted one factual slip-up on the front, and I've also added the key to memrefin[addr] which @myco posted when it was first introduced on Alpha.
The dual wave-read code is also 99% @myco's - as if you couldn't guess!

^ Excellent, the memref key makes everything a lot clearer - thanks again!
