Can you clarify what you mean by this statement? It doesn't really fit well with my understanding of the RPI design, other than the fact that it's a SoC and the GPU and CPU are on the same chip.
- pizza234 7y agoThere is another comment explaining it; in short, "boots first and has low level control of the SoC". Defining "main processor" is certainly arguable, as there isn't a unique way of viewing the architecture, but on the other hand, the idea that ARM boards are "very custom" still stands.
