That feature (Search Assist) can be turned off in the settings, and we have a noai.duckduckgo.com domain that automatically turns it off along with other AI features. That said, Search Assist just summarizes web content and does not generate its own answers, but the summary is AI generated.
I can see by dragging the slider around and comparing to the ground truth that it is making things up that look plausible to what is there.
Just keep any numbers out of there. Remember what happened with the Xerox scanners and JBIG2 compression where numbers got substituted with similar looking numbers.
I wouldn’t say it didn’t have any microcode. It actually had a small PLA for sequencing the multi-cycle instructions. [0]
I don’t think anyone would actually label it as microcode (not when the entire point of RISC was to avoid microcode) they would call it a sequencer or finite state machine; But really it’s the same thing. It’s certainly much simpler than the full microcode of any contemporary CISC, and the bulk of instructions execute in a single cycle without using it.
If you want a design with zero microcode, you really need to look at MIPS, or the original Berkeley RISC. Those ISAs go out of their way to avoid multicycle instructions. Not entirely successfully, but they don't use PLAs [1] to implement any state machines for the few remaining instructions like multiply and divide.
[1]At least on the few MIPS designs I've looked at.And I'm not sure if they deliberately avoided PLAs for doctrine reasons, or it was just more efficient to do so.
It turned out the die area saved by eliminating the complicated sequencer and microcode ROM enabled them to add another 16 datapath bits and make the first 32 bit microprocessor.
Yes, once the market came into existence, ARM was well situated to take advantage of it.

"All" is a tricky term to use here. They got some. An appreciable amount even. Their business model leaves quite a bit on the floor compared to desktop chips.
This change suggests that passing pointers is "generally safe", the unsafe boundaries are when they are de-referenced. It sounds like the Marshal methods are probably going to get a lot of surprising new safety warnings, but not all of them just because of the use of IntPtr. This change does open more opportunities to switch IntPtr to more explicit type-safe options like void* or byte* as the new compiler no longer needs unsafe {} blocks around just passing around pointers from one function to another.
Anubis is actually not a cat. The original Egyptian deity is a god of death, and has a canine head. Anime catgirls and dog girls can look similar at first glance.
If you want to write faster Z80 code, pretend it's a Game Boy, and use the IX/IY registers sparingly. You can use 256-byte aligned tables. Then you put your index into the low byte of the register pair, and which table into the high byte of the register pair. You don't even need to completely use the table if you don't need all 256 entries, you can treat the rest of a table as free space to put other variables in there.
edit: At the time I made the post, the thread title was something like "Doing Z80 40 years later", and did not mention the ZX spectrum.
It’s a Spectrum. You’re going to do a HALT to sync with the start of the frame and then cycle count to prevent tearing. You can disable interrupts if you know how long you have to render your frame before the beam catches you (or let it pass then start rendering).
