Hi all,

i am stuck with an idea of comparing three different programs, which are created using different programming techniques, but they are meant to be doing the same function.

The techniques used:

1. C language.
2. Assembler.
3. Real Time Operating System.

The three different programs will be compared in terms of:

1. Cost.
2. Memory Demand.
3. Speed of Execution.

When i decided on the Speed of Execution, i thought the best way to do is just use the Development enviroment facilities to measure the speed of execution, with things like the 'Stop Watch'. But then, i was asked to agree on a methodology to measure the speed of execution on the actual hardware. If you can help with that or know of any techniques that can help me do that please, let me. Because i really need your help with this.

Thank you so much,
Many thanks.

well, you probably want to set the timer within the code itself for each one of them. I'm pretty sure that all of the codes will or should have time that is set up for a machine level that is usually computed in the nano seconds (just very small..) you may want to start that at the time you execute the codes and stop it when it's done.. then substract the time after and the first time you run it, then you'll receive the time result, here you can compare it for each techniques..

Thanks Hello World,

I can measure the speed of execution within the Integrated Development Environment. What i am asking about is if i apply the software to a hardware application, how would i be able to test the speed of execution and lateness within the hardware.

Many thanks for your help.

Hmm.. this is a little bit tricky, but since u're talking about assembly, each time hardware processes something and send it to other part in the machine, then they'll send signal 1 if I'm not wrong? Then is there a way to calculate the time when 1 is received from the other part of the machine? I probably don't have the right to help you because I'm not into hardware development...

Hi, Hello World,

Thanks again. The easiest way to measure the speed of execution is to use the simulation facilities, But i am still having trouble deciding on a methodology on how to test the speed of execution in real life and make sure that everything is as expected to be. Last night i was working on a piece of hardware that i have built myself and trying to think of the best way to measure the lateness and the speed of execution. I thought of using Interrupts.

I mean applying Interrupts to the Microprocessor and then, use the oscilloscope to measure the delay between the input and the output. But, i am still not quiet sure that this is the best way to do it.

Many thanks.
