What's really amazing is they don't run without a hitch, there is an acceptable error rate that they recover from. That is part of why systems are more stable today than previously, more threads, more cores, if a thread crashes it doesn't take down the entire system. It's not just at the CPU level but errors still exist they just don't take down entire systems as often.

I am in chip design from 1984 and tried many times to explain to people what am I doing. If I would have had these videos my explanation could have been easier. The animation and graphics are unbelievable quality. The Part 1 is a good umbrella explanation of the chip design in general and CPUs in particular. I will call this the 10.000 feet view. The Part 2 is the 1 foot view directly into the processor architecture so some industry lingo and knowledge is required. I would have liked to have a 3.000 feet and a 100 feet view for popularizing chip design and CPU for people who do not have an electronics background. Intel has all the capabilities to do it so please consider it. In the times of Artificial Intelligence and Biotech advancements making more people understand where all started and how it humans can benefit from their merger should be a good topic to cover. Looking forward for new videos from you.

Think of it in this way, trillions of electric signals go through a CPU, these electric signals are sometimes of low current, sometimes of high current. Low current is interpreted as 0, while High is interpreted as 1. Now we have all the characters that make up the language of computers. The CPU then uses Hardware languages like VHDL to operate these 0s and 1s. This is how Physical things do software work.

It feels like uOps are the actual basic instruction set. Which makes it feels like ISA is actually a higher level language hardcoded in the hardware. But then what is the point of the higher complexity ISA and not using uOps as the basic instruction set directly? Is it why x86 has like 2500 instructions in its ISA? And RISC-V on the other hand as less instructions. 50 I think. Which sounds like many more than the really basic instructions so I guess they also use uOps?
@storyls
3 жыл бұрын
>Why not use uOPs as the basic instruction set directly? You could, but the issue is that it’s going to cost you a lot of memory. Really it’s just space complexity, instructions take up little memory, uOPs a lot. uOPs are basically a bunch of wires that go throughout the CPU and say things like “connect register 4 to the bus leading to the ALU” or “write output of ALU to the register file.” Each uOP also has to tell which modules of the CPU stay on and which stay off, and for the vast majority of instructions, each uOP is going to be sending a LOT of 0s to all the modules that don’t need to be operating for this instruction. While an instruction alone can take up say 2 bytes, each uOP could be telling hundreds of modules what to do. The decode stage itself is pretty dumb usually. It essentially uses storage, the instruction is an address and in that storage for that address there is some firmware for all the uOPs. Also each architecture can have all sorts of different uOPs for the same ISA.

This is really great stuff, but I found a bug in your code at the 5:00 mark... A 5 GHz processor doesn't mean "each completes in 5 billionths of a second" -- it means that each completes in 1/5 of a billionth of a second. It's a clock every 200 ps(thanks Ryan), not a clock every 5 µs... But at least we didn't divide by zero!

Incrediby well produced and informative. One question: at 4:58, shouldn't the time to complete a stage be 0.2 (1/5th) billionths of a second if the CPU is running at 5GHz? It looks like 5 billionths of a second per stage would give a 200 MHz clock speed.

compilers can currently unroll loops with constant loop counts, but could this more efficiently be handled by hard-coding instructions to a branch predictor?
@storyls

As in an instruction hinting to the cpu what branch to take? It’s possible. The Pentium 4 actually did support these branch hints, but it seems Intel has abandoned that since for whatever reason. I think it’s because modern hardware branch prediction has gotten good enough that it’s not needed anymore. Loop unrolling still benefits, even if you hint to a cpu to always take a branch, with a loop you are guaranteed to guess wrong at least once. Not having branches also allows the compiler to make other optimizations.
