Yes here it is...

I began to wonder if it is actually an EA calculation complicating matters because the opcode used for all the work has circular buffers configured for X: and Y: (the DSP 'm' registers)

However even if this is the case the timings don't match a real machine so it's worth a look anyway.

I'll try a simpler addressing mode later.

Very interresting, I look at it immediatly.

Could you send me your benchmark program, so I can launch it and have a look at the instructions in detail ?
