Figure 4.1 shows a block diagram of the core module.
The block diagram shows the main hardware components and buses on the core module and how they connect to either the ARM922T stripe or to the user programmable PLD.
The components connected to the stripe include the on-board SDRAM and flash, a serial interface, and the debug interfaces.
The PLD connected components include memory, clock generators, LEDS, switches, and connections to the Integrator system buses. Control logic for these must be provided in the PLD design.
The core module is supplied with four PLD designs stored in the config flash. These are:
- Basic Example Image
This design configures the PLD with a basic example image. The image contains registers to set the on-board clocks and to read the user switches. It is designed to allow you to develop and add your own IP for use with the ARM core.
For a description of this image, see Chapter 5 Basic Example Image for Simple Standalone Operation.
- CM Image
This design configures the PLD with a design that functions as an Integrator core module with an AHB interface. The core module can be used its own (standalone) or with an Integrator/AP motherboard, and is capable of running boot monitor or GDBstub over a serial line.
For a description of this image, see Chapter 6 CM Image for Operation Standalone or with an Integrator/AP.
- CP Image
This design configures the core module when mounted onto an Integrator/CP baseboard. The PLD is programmed with the appropriate image containing PrimeCell peripherals and interface controls for the interfaces provided by the baseboard.
For a description of this image, see Chapter 7 CP Image for Operation with an Integrator/CP Baseboard.
- IM-PD1 Image
This design configures the core module to operate with an Integrator/IM-PD1 mounted onto it. The design contains the appropriate PrimeCell peripherals and interface controls to drive the interfaces provided by the IM-PD1.
For a description of this image, see Chapter 8 IM-PD1 Image for Operation with an Integrator/IM-PD1
All four images are programmed into flash during board manufacture. However, the source code for the basic example and the CM images only are supplied with the IntegratorCM922T-XA10. Source code for the CP and IM-PD1 images are supplied with the Integrator/CP and Integrator/IM-PD1 products respectively.
