What's the difference between core, processor,cluster and CPU?
Hi Grady
Core = CPU or GPU. Example: "a ARM Cortex-A15 quad core processor"
Processor = can be the CPU or the full chip. The full chip should be called a system on chip (SoC) as it includes much more than the CPU. In the case of ARM Cortex-M processors, they tend to be called microcontrollers.
Cluster = group of CPUs or SoCs, depending on the context.
These are not definitions specific to ARM.
