I'm working on a design for a high-efficiency instruction decoder for a new #Z80 core design. Apparently the world doesn't have enough open-source Z80 core designs yet.
I'm trying to make this core much more cycle-efficient than normal Z80 cores, or even eZ80 cores. A normal Z80 core takes 4 clock cycles for the simplest instructions. I'm trying to get those down to 1 clock. I'm using a synchronous memory bus, and a loosely coupled instruction prefetch and decode unit.

This week on the blog: Given that for 10 years now I've used the 48k Spectrum as my default platform for testing my Z80 code before moving it somewhere less cozy (Mega Drive, CV, TRS-80...) it's kind of silly that I've never really systematically dug into the system line itself to make it dance and sing.

Today we fix start fixing that, with the now-traditional tour from the BASIC standpoint.

Giving the ZX Spectrum a Fair Shake

Last month (just a couple days before my Exidy Sorcerer article) the ZX Spectrum celebrated its 44th birthday. I have written shockingly little about the system given that it still remains the firs…

Retro Computing Nerds, especially Z80! I'm trying to use DeZog to reverse engineer a ROM routine. I need to implement bank switching via the ioMMU config. I have it half working, but it doesn't appear to switch properly unless I code case for all banks. Does anyone have any advice on this? I have been looking at DeZog's source code and half getting somewhere, but the documentation is vague.

I've rewritten my #Console8 logo player -also works on #AgonLight - and updated the video file for 2 reasons. 1. it was a bit long playing the whole thing, and 2. I wanted to play a higher resolution video, covering as much of the screen as possible. With a bit of video editing (cutting and cropping to make the most of the logo at the end), plus taking advantage of the VDP code for both decompression and bitmap expansion, this is what my boot sequence looks like. I've left the logo to linger a little, but that's optional and a quick change to the script.
