Hi –
One item that came up at the European User Group Meeting on Sept 16th was how to get information about the ARM Instruction Set.
ARM has a Manual (in several volumes) called the ARM Architectural Reference Manual which covers the instruction and you can download from here:
In order to download it you do need to register with the infocenter website (Name, Company, Email address, country where you live) and you do need to click-thru an agreement which states you don’t intend to use the document for the purpose of investigating if the ISA violates patents. That’s about all. You don’t need to be a silicon provider or an ARM licensee or anything like that.
HTH,
Rod.
