#98550 - Cycles vary? Responding to: ???'s previous message |
Not sure about C but I used basic once to write a program which required precision timing ie. needed to account for cycles. I tried pre-caclulating the cycles with a simulator and building it into the program, the cycles varied in my case while checking time required to execute loops. I was unable to achieve the accuracy I required in my case to this point. May have been a sloppy compiler or bug in simulator probably gets complicated. I think you can use assembly statements in a c program can't you? You could use assembly for the critical parts of your program and C for the parts of the program not dependant on time.
Just a thought, may be way off base. Others can confirm or flame! Regards James krushlucki |

| Counting cycles... possible in C? | 01/01/70 00:00 | |
| You need a Profiler | 01/01/70 00:00 | |
| The compiler knows | 01/01/70 00:00 | |
| Source code useless | 01/01/70 00:00 | |
| That's why you need Assembler! | 01/01/70 00:00 | |
| nohohoho | 01/01/70 00:00 | |

| Cycles vary? | 01/01/70 00:00 | |
| I know | 01/01/70 00:00 | |
| absolutely, but what good does it do | 01/01/70 00:00 | |
| other way round | 01/01/70 00:00 | |
| Yes, the things posted apply in this cas | 01/01/70 00:00 | |
| exactly for this reason | 01/01/70 00:00 | |
| how can you automate that it is small en | 01/01/70 00:00 | |
| Use Microsoft Excel | 01/01/70 00:00 | |
| excel and conditional branches ? | 01/01/70 00:00 | |
| That's why | 01/01/70 00:00 | |
That makes absolutotally no difference, | 01/01/70 00:00 |
