inline instruction-fix mechine cycle-variable machine cycle

[diod]

hi
could you explain me what are these in computer architecture:
inline instruction?
fix mechine cycle?
variable machine cycle
best regards

1. In-line instructions are assembler language instructions often used for speed in for example a C program.
2. Fixed machine instructions take the same time to execute regardless. e.g mov A,#1, rrc A on an 8051
3. Variable can take any amount of cycles depending on certain register values e.g LDIR on a Z80

Here is a better explanation of #1: https://www.electro-tech-online.com...5_201-1520May20classandobjects_inlinefunc.pdf

What it basically means is that the assembly code of an "inline" procedure is inserted for every instance of it's use. It won't be called as a subroutine.

Inline code can also mean interspersing assembly with C programs.

The end result is indeed faster execution.

Your explanation if far more intuitive than the PDF link that is more about syntax than explanation.

Thanks. That's why I added my interpretation because it wasn't clear. As you said it was the syntax. It's good to have both.
