2.1 Overview of the ARM Development Board
The ARM Development Board is a platform that is suitable for code development and
exploration of embedded ARM processors. It is a convenient means of evaluating the
Advanced RISC Machines’ Thumb-aware (ARM7T) family of RISC processors.
The ARM Development Board has been designed to conform to the
Advanced
Microcontroller Bus Architecture
( AMBA ) specification. This specification defines an on-chip
communications standard for designing high performance 32- and 16-bit embedded
microcontrollers. A convenient way to view the ARM Development Board is as a
microcontroller design in discrete components. This means that it is possible to observe bus
transactions and peripheral accesses using standard test equipment. Thus, a typical
microcontroller design can be easily observed and prototyped.
Because the processor in the system is little more than ARM core it is possible to use an in-
circuit emulator (ICE). This enables a system design to be tested and debugged at the
processor level. In addition processors with EmbeddedICE capabilities can be debugged
directly using the EmbeddedICE interface. The ARM Development Board also has a parallel
port and two serial ports that allow it to be connected to a variety of hosts. Using a monitor
program supplied with the board, the user can download and run code in collaboration with
the ARM Software Development Toolkit.
The ARM Development Board shows how to design a system based on the AMBA
specification, comprising a multi-master system bus (ASB) and a low-power peripheral bus
(APB). While on-chip techniques may differ, the main system modules and their interconnect
have been preserved.
The following are useful reference documents. You should refer to these to understand the
functionality of AMBA modules.
• AMBA Specification(ARM IHI 0001)
• Reference Peripherals Specification(ARM DDI 0062)
2.1.1 Using ARM resources in your design
This manual contains both the circuit description (and schematics) of the ARM Development
Board and a description of programmable logic devices used.
The programmable logic equations and schematics can be obtained from ARM for use in
your own designs. These are provided to help you design your prototype target hardware
systems.
Both hardware and software are provided as tutorial aids and demonstrate techniques rather
than an optimal implementation. Please feel free to use the schematics and programmable
logic equations provided as a basis for your own system designs.
