Pete Cockerell's ARM Assembly Language Programming Book

Sun Dec 22, 2013 1:42 pm

This excellent book is a wonderful introduction to ARM assembler. It deals with the ancient ARM2 processor (as used in the original Acorn Archimedes computer - back when ARM was Acorn RISC machine :-) ) but almost all of it is still relevant.

Pete has kindly made it available for free at http://www.peter-cockerell.net/aalp/html/frames.html

Is it available as a single consolidated PDF or do I have to pull the pieces and "glue" them together?

someone's done all the hard work of glueing it together for you :-)

Thanks. My Pi may be running RiscOS again in the near future.

I love reading old computing documents, and then realising how recent that was...
In the brief history of
microprocessors, the addressing range of CPUs has grown from 256 single bytes to 4
billion bytes (i.e. 4,000,000,000 bytes) for some 32-bit micros. As the price of memory
continues to fall, we can expect 16M and even 32M byte RAM capacities to become
available fairly cheaply.

http://opencores.org/project,amber

a project named amber can be found at open cores, not hard at all to simulate with free tools. remember no two engineers create the same design/code to the same problem (hardware or software) so this isnt exactly how the arm worked inside nor how current arms work inside, but you can still learn quite a bit by watching your code execute inside a chip.

And the instruction set from arm2 to arm4 and newer has a great deal of overlap, I think the differences were mostly related to the status registers, the basic alu, load/store, etc are the same or at least were built upon with armv4 and newer.

arm uses the amba/axi bus for interfacing not a wishbone, the details are more complicated but it is at the end of the day a modern bus with handshakes, various transactions can be in flight at the same time, etc.

Good links to arm assembly stuff, thank you very much, will definitely be spreading those links around...
