IAR v/s KEIL for 8051

Keil is an welll-integrated toolkit.Now its name is uVersion 2.Once I used SyncMOS 51 chipset to build a voice terminal. I think you can do everything in Keil uVersion 2, coding, compiling, debugging, managing your project file. There is one issue, when I use hardware emulator to debug , I can't debug in source code level because all the source code is invisible.

The performance of compiler, how to evaluate it? I think the code we design decide the performances.Ineffective code causes poor performance.

Maybe you can lookup 8051 microcontroller FAQ in

Good luck

I used a version of IAR back around 1990, and a version of Keil around

Keil is now uVision 3. I highly recommend it. The built-in simulator is fantastic.

Both are well thought of. IAR are notorious for restrictions such as; dongle required and a special code that takes a week to get, you don't buy the IAR compiler, you buy the right to use it ... meaning you can not resell it.

Keil is much less restricted and has put out a quality product for many years.

I have used Keil for the past two years and am quite pleased with it. I recommend spending the extra bucks and getting the uV3 IDE as well. I used to use the Keil tool set with Silicon Labs' IDE and it didn't work as well.

My Keil came with a dongle :-(

Five or six years ago, when I was using Keil 5.5, it did not have any use prevention, er, I mean "copy protection", but I heard complaints on usenet about the European version being dongled. You are apparently in England.

I don't know if the U.S. version is still dongle (and other impediment) -free, but if it is, that would be more than enough to recommend it above IAR, if IAR is dongled. Version 5.5 was more than "good enough," and I hear the newer versions are even better.

I have version 7.50 (US) and there is no dongle or other impedimentia.

Very pleased with it, too...

The US version is still dongle free, and we have been extremely happy with it for developing 8051 code.

Keil and IAR are great tools, but have you considered alternatives?

Not for serious work.

Keil recommend (or used to) this one for non-serious applications.

As the "Technical Support" page doesn't seem to have been updated since their fax problems in March 2003, they might possibly not be the most responsive vendor on the planet. Maybe Ontario Telephone is still working on repairing the cut phone line?
