Introduction1.1 About the ADKThe ADK comprises the building blocks required to create an example system based onthe low-power, generic design methodology of the Advanced Microcontroller BusArchitecture (AMBA). Three preconfigured and validated examples enable you todevelop custom devices in very short design cycles. Therefore, you can easily reuse theresulting subcomponents in future designs.NoteADK EASY environments use AHB and APB protocols.1-2 Copyright © 2003, 2007 ARM Limited. All rights reserved.

Introduction1.2 AMBA signalsThis section describes the following signals:• AMBA AHB signals• AMBA APB signals on page 1-5.NoteFor a description of the non-AMBA signals used in the ADK, see Chapter 3 AHBComponents, Chapter 4 APB Components, and Chapter 5 Behavioral Models.1.2.1 AMBA AHB signalsTable 1-1 lists the AMBA AHB signals used in the ADK.Table 1-1 AMBA AHB signalsSignalDirectionSlave Master Arbiter DecoderDescriptionHADDR[31:0] Input Output - Input The 32-bit system address bus.HBURST[2:0] Input Output Input - These signals indicate if the transfer forms part ofa burst. Four, eight, and sixteen beat bursts aresupported and the burst can be either incrementingor wrapping.HBUSREQx - Output Input - A signal from bus master x to the bus arbiter toindicate that the bus master requires the bus. Thereis an HBUSREQ signal for each bus master in thesystem, up to a maximum of 16 bus masters.HCLK Input Input Input - This clock times all bus transfers.HGRANTx - Input Output - This signal indicates that the bus master iscurrently the highest priority master. Ownership ofthe address/control signals changes at the end of atransfer when HREADY is HIGH, so the mastergets access to the bus when both HREADY andHGRANT are HIGH.HLOCK - Output Input - When HIGH, this signal indicates that the masterrequires locked access to the bus and no othermaster must be granted the bus until this signal isLOW.ARM DDI 0243C Copyright © 2003, 2007 ARM Limited.
