STn8810 architecture overview
STn8810S12
The STn8810 platform comprises an industry-standard ARM CPU supported by smart
audio and video accelerators, on-chip memory and controllers, a rich set of peripheral
interfaces, and a power management system. The processors, controllers, memory and
peripheral interfaces are connected by a multi-layer advanced microcontroller bus
architecture (AMBA) for efficient data transport between the components.
The overall STn8810 architecture is illustrated in Figure 3.
