Difference between static memory allocation and dynamic memory allocation
...ister' variables. As expected, register variables should be allocated on a CPU's register, but the decision is actually left to the compiler. You may not turn a register variable into a reference by using address-of.
register int meaning = 42;
printf("%p\n",&meaning); /* this is wrong and will...

What are Transient and Volatile Modifiers?
...le variable will be read from the computer's main memory, and not from the CPU cache, and that every write to a volatile variable will be written to main memory, and not just to the CPU cache.
2) transient keyword cannot be used along with static keyword but volatile can be used along with static.

What are some resources for getting started in operating system development? [closed]
...as already laid out for you. For example, contact Intel and ask them for a CPU card for your type of CPU! This will lay it out for you - the "pin-outs", interrupts, opcodes, you name it!
Remember the hardware makes it all possible. Study the hardware. You won't regret it.

Is inline assembly language slower than native C++ code?
...ion scheduling, for example, is very hard to tune by hand) and modern CISC CPUs have very long pipelines too.
For some complex microcontrollers even system libraries are written in C instead of assembly because their compilers produce a better (and easy to maintain) final code.
Compilers sometimes...
How to free memory in Java?
...new in the last six years) G1 collector is a low-pause model; it uses more CPU overall, but does it's best to never force a hard-stop on execution. Since server CPUs now almost all have multiple cores, this is A Really Good Tradeoff to have available.
Look at your flags tuning memory use. Especial...
Reading binary file and looping over each byte
