want arm basic compiler

 

I know BASIC, I know what a compiler is, what is arm?

You want help try giving more info.

 

An arm is the thing that hold your hand to the trunk of your body... More seriously an ARM processor is an Advanced RISC Machine. http://en.wikipedia.org/wiki/ARM_architecture

 

Is there only one op code set (only one ARM code)?

 

No there can be variants in the instruction set depending on the processor you use. For example, look at the AT91 32-bits series from ATMEL (SAM series). There are differences between say ARM7s and ARM926 wich are from the same manufacturer. TI as another set of instruction. In common though, they all use the RISC architecture (load/store/etc).

OK, the reason I asked is the OP needs to clarify what he wants. Thanks for the info though, learned something.

 

To the OP, a small google search for: "arm basic compiler" gives you everything you need. Did you even tried that?
