AMBA Design Kit Technical Reference Manual - ARM Information ...

Functional OverviewTest interface controller• now included within the static memory interface• converts test vectors applied on the external pins of the device into valid AHBtransfers on an internal bus• to be used to test relevant ARM processor cores.Bus matrix• enables parallel access paths between multiple masters and slaves• improves overall systems bandwidth• gives increased system design flexibility.AHB to APB bridge• provides a 16-slot interface between the high-performance pipelined AHB andthe lower performance peripheral bus• supports AMBA 3 APB protocol.Example bus master (32 or 64 bit)• a simple bus master that is intended to act as a reference framework for bus masterdevelopment• demonstrates bus master activity by read-pause-write bursts• interfaces through the AHB-Lite to AHB wrapper• configurable address and pause length.AHB to AHB bridges• provide an interface between two separate AHB buses, supporting variousclocking schemes.Interrupt controller• generates the two ARM interrupt signals from the multiple interrupt sources thatcan exist in a system• individual bit-level control of the masking of interrupts• interrupt driven or polled method of operation2-4 Copyright © 2003, 2007 ARM Limited.
