Questions tagged [arm9]

ARM9 is 32-bit RISC CPU family based on ARMv5 architecture. The ARM9 processor family includes ARM926EJ-S™, ARM946E-S™ and ARM968E-S™ processors.

With this design generation, ARM moved from a von Neumann architecture (Princeton architecture) to a Harvard architecture with separate instruction and data buses (and caches), significantly increasing its potential speed. Most silicon chips integrating these cores will package them as modified Harvard architecture chips, combining the two address buses on the other side of separated CPU caches and tightly coupled memories.
