An ARM968E-S processor with real-time emulation support
An AMBA multi-layer Advanced High-performance Bus (AHB) for interfacing to the
on-chip memory controllers
Two DTL buses (an universal NXP interface) for interfacing to the interrupt controller
and the Power, Clock and Reset Control cluster (also called subsystem).
Three ARM Peripheral Buses (APB - a compatible superset of ARM's AMBA
advanced peripheral bus) for connection to on-chip peripherals clustered in
subsystems.
One ARM Peripheral Bus for event router and system control.
