[Coco] Optimizing 6809 Assembly Code: Part 2 – Speedup Storing Data – Unrolling Loops

[Glen Hewlett]

Hi Mark,

I love to hear stuff like this!  That’s the main reason I posted the blog.  Of course it’s also a great reference for me to also refer to… :)

Yeah, I hear you about keeping things the same at first, then optimized later.  Very important.

Cheers,
Glen
