ARM9

Switching from a von Neumann architecture entailed using a non-unified cache, so that instruction fetches do not evict data (and vice versa).

ARM Holdings neither manufactures nor sells CPU devices based on its own designs, but rather licenses the processor architecture to interested parties.

Integrated device manufacturers (IDM) receive the ARM Processor IP as synthesizable RTL (written in Verilog).

This allows the manufacturer to achieve custom design goals, such as higher clock speed, very low power consumption, instruction set extensions, optimizations for size, debug support, etc.

To determine which components have been included in a particular ARM CPU chip, consult the manufacturer datasheet and related documentation.

The ARM MPCore family of multicore processors support software written using either the asymmetric (AMP) or symmetric (SMP) multiprocessor programming paradigms.
