It should be noted that in order to develop StrongARM, DEC had to license the ability to do so from ARM. This was the first time ARM gave a company an architecture license allowing them to actually design their own [[microarchitecture]] that implements the ARM instruction set. Previously ARM had only offered core licenses which gave a licensee an ARM-designed core they can use but they were not allowed to develop their own design. | It should be noted that in order to develop StrongARM, DEC had to license the ability to do so from ARM.
