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
 

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.
