Product Information
The MAJIC controller provides a high-speed hardware interface between ARM processors with the EmbeddeICE on-chip debug interface and industry standard debuggers. It is available with a choice of EPI debuggers or may be used with the ARM debuggers and any RDI 1.5.1 compliant third party debugger.

Now, when using SoC devices, you can have the same level of control and visibility of the embedded CPU operations as you would with in-circuit emulators in traditional discrete CPU designs. The result is faster software integration, better testing, and improved time to market. The MAJIC probe's ability to expand to support additional cores, debug interfaces, and SoC devices eliminates the need to buy new emulators for each new project, thus reducing project costs.

Completely non-intrusive, the MAJIC controller communicates to the CPU core by JTAG using the existing boundary scan pins. It uses no target memory and requires no porting to the target system.

Complete processor control means you can start, stop and single-step execution; read and write to registers, memory, and system I/O; and download code to target RAM - all within most industry standard debugger interfaces.

Using the on-chip debug facilities of the ARM EmbeddedICE (DI) Macrocell, the controller provides visibility of the program's behavior even when the CPU is executing from cache, flash, or ROM embedded within an SoC.

A MAJIC controller can support multiple SOC-based targets using adapters, cables and target connectors defined as specific Configuration Kits. The ARM Configuration Kit (CK-01AM) contains the appropriate firmware and user license to match the ARM CPU's DI on-chip debug facilities.

The MAJIC probe is ready to run with the EPI or ARM software tools and any board that supports connection to the on-chip debug interface. These tools work together to provide you with a proven working environment.

The MAJIC probe is available as a stand-alone unit or as a complete debugging kit. The kit contains serial and Ethernet cables, source-level debugger, and one year of free maintenance, support, and updates. Part number: MAJIC-KIT.

Complete development kits are also available that include a compilation toolkit. See the 'Price and Configuration Guide for ARM tools' for full details of these development kits.

Major features of the MAJIC probe include:

Ethernet Interface
The 10/100Base-T Ethernet interface provides many advantages over serial or parallel interfaces to the host. Download of your application code is over ten times faster than with serial interface. This will significantly reduce the amount of time spent waiting for code changes to download to your target board.

Network connection allows remote operation of the MAJIC controller. Now you can access the lab setup directly from your desktop. This allows multiple engineers to share a common test bench.

Flash Memory
The firmware for the MAJIC probe is easily upgraded without the need to replace ROMs.

New firmware updates will be available on our FTP site. Use the simple program provided to automatically program the updated firmware into the on-board flash memory.

Flash memory makes it easy to program an IP address into the MAJIC probe for point-to-point Ethernet connection to a host computer.

Internal RISC Processor
The use of a high-performance internal ARM processor allows fast response to debugger operations such as single-stepping, and downloading of application code to the target.

Status LEDs
The MAJIC probe provides five LEDs which show the operational status of the controller. The LEDs also indicate the results of the built-in self-test that is automatically performed upon startup.

Convenient Reset Switch
A convenient rest button on the MAJIC probe is protected against accidental activation, yet is easily accessible by the user when a complete system reset is desired.

Choice of Configuration Kits
The MAJIC family of probes includes a selection of optional Configuration Kits that configure a MAJIC controller for a specific architecture. To order the unit preconfigured for the ARM cores, order option CK-01AM. This option provides the firmware, hardware, user license and inter-connections necessary to support the standard ARM target connectors.

Please refer to the Configuration Kit datasheet for detailed specifications on the other CPUs and on-chip interfaces currently supported.

Programmable JTAG Clock
The MAJIC controller features a programmable TCK with a 0 to 40 MHz range. This allows you to tailor the JTAG operation to match the performance of your target. It also means that you can use the MAJIC controller with low-speed ASIC emulators or with FPGA implementations of your SoC design.

RT Clock Support
A MAJIC probe provides full support for the ARM RT clock.
This means a MAJIC probe will support the synthesizable cores and debugging during sleep mode operation.

Programmable Trigger Control
The MAJIC controller gives you control over both the trigger-in and trigger-out signals. The trigger-in signal may be used to create a breakpoint or synchronize execution. A trigger output may be set to show execution status, indicate memory accesses, or indicate a memory test failure.

International Power Supply
The MAJIC probe operates from a standard 5V power source. It comes with an external UL/CE-approved AC adapter, whose AC input range is compatible with all international AC voltage and frequency ranges. A standard three-wire power connector is compatible with readily available power cords through the world.
