Raspberry Pi – Where to start?
At its core, the Raspberry Pi uses the Broadcom BCM2835 System-on-a-chip. This single chip contains an ARM1176 CPU (normally clocked at 700MHz) a VideoCore 4 GPU, i.e. a low-power mobile multimedia processor (also used in the Roku-2) 256 MByte SDRAM in addition to the ARM’s MMU, a second coarse-grained Memory Management Unit for mapping ARM physical addresses […]
