The wiring has lower resistance for a bunch of different reasons, so the heat has a tendency to be concentrated on the transistors themselves (which are mostly silicon, just doped).

Nope, thermodynamics is weird at small scales. Hot spots can absolutely reach 1400C if not designed not to. Sophie Wilson (initial architect of the ARM processor) has talked about how poorly designed silicon can reach point temperatures h

Except hot spots quickly reach the melting point of silicon these days. That creates, let's say, a rather steep drop off in performance.

In practice, branch target predictors are also used for conditional branches too, and even unconditional, direct jumps. Yes, the target can (sort of by definition) be computed from the instruction and the pc, but the by using the branch ta

Inflating SpaceX's perceived value would have been the primary goal for a lot of the business for at least the past year leading up to the IPO.

I think it's more that Space X's valuation is ridiculous, and they need acquisitions that are ridiculous to pretend that the emperor is still wearing clothes. When cursor is selling for $60B, then grok has to really be worth sever

This library's default is greyscale anyway, so it's by default colorblind friendly.

Or, not every UI library is intended for use cases where a13y even makes sense. Like a debug UI in a game engine, or in an embedded device that doesn't even have input for a13y.

And the got is just a big table of pointers like any other table of pointers your application manipulates as it runs. This isn't meant as a reductive take, but instead that there is a difference between completely describable in C like

That's not really patching though, any more than any use of function pointers is patching.

Not on modern archs that provide decent support for PIE (position independent executables).

Those mappings by default all go to the same shared memory. Unices have been sharing executable memory between processes longer than there's been mmap for user space to do the same thing themselves. I remember seeing it in the 2BSD ke

So, I've read Computation Structures. And agreed, an absolutely fantastic text. [0] However, my question is kind of orthogonal to vertical versus horizontal microcode. As a counter example I'd point to the microcode format of th

Poorly designed or managed chips can reach the point that hot spots in the silicon literally melt, which happens at ~1400C. Thermodynamics sitting on an insulator (relative to the metal portions of the chip at least) on very small scales i

I found it interesting that this uinstr format doesn't include omnipresent control flow bits like I see in most uinstr archs. I was going to ask about RNI being it's own instruction, but looked at the microcode dump you linked to

Basically why my car is so old it doesn't even have a CAN bus. Roslin: I heard you're one of those people. You're actually afraid of computers. Adama: No, there are many computers on this ship. But they're not networked.

I wouldn't quite go that far. Linux runs on nommu systems. With some psram you should be able to get a version to run on at least the rp2350 using the riscv cores with relatively minimal fuss. Is that a good idea? Well, not really.

I image that'd be handled via a fairly regular minor bit of additional fine tuning to update them with new information rather than polluting the context space.

When you say that the 125 added memory management, what does that mean a little more specifically? My guess is either PDP-11/z280 style paging without page tables (the 16 bit address space makes just having enough IO registers to cove

Not just the TLB, but the L1 D$ will be very unhappy as well. All heap objects being page aligned on most microarchs ends up making every object start at cache set 0 because the set determination ends up being indexed off of the offest wit
