Does each assembly language correspond to one instruction-set-architecture?
This is a quote from wikipedia:
Each computer architecture has its own machine language. Computers differ in the number and type of operations they support, in the different sizes and numbers of r …

Why are word sizes in modern CPU’s a power of 2?
Word size of most modern cpu’s is 32 or 64 bits. Both are a power of 2.
This looks “intuitively reasonable”, because a bit has 2 states, but I don’t actually have a hard argument for why this is the …

A microkernel fully hardcoded in hardware?
That is, a kernel that is not stored in RAM, and loaded into CPU registers after an interrupt or system call, but is instead a fully hardcoded part of the CPU itself, so that a system call/interrupt never …

Neural branch predictors linear, classical predictors exponential, in resources?
Wikipedia states:
The main advantage of the neural predictor is its ability to exploit long histories while requiring only linear resource growth. Classical predictors require exponential resource …

Information theory of instruction set architecture design?
Intuitively, it seems like we can think of machine instructions (or programs) as "messages to the CPU". Some messages are more probable than others. E.g. …

Do most computational efficiency increases due to increased transistor count in the last 70 ...
So I am trying to understand how increasing the number of transistors in a CPU can help you increase computations. I’ve looked online but couldn’t find a definitive answer. … By employing smart control architectures (i.e. in the control unit), a CPU can smartly handle multiple instructions that don’t require the same CPU components at the same time, thereby employing instruction-level …
