Introduction

1.2.2 ARM926EJ-S PXP Development Chip

For details on the ARM926EJ-S PXP Development Chip, see ARM926EJ-S PXP

Development Chip on page 3-3 and the ARM926EJ-S PXP Development Chip

Reference Manual.

1.2.3 PB926EJ-S FPGA

The FPGA provides system control and configuration functions for the PB926EJ-S that

enable it to operate as a standalone development system or with expansion RealView

Logic Tiles or PCI cards. See FPGA on page 3-17.

The FPGA also implements additional peripherals, for example the audio CODEC,

USB, Ethernet and PCI interfaces.

1.2.4 Displays

The ARM926EJ-S PXP Development Chip outputs signals for a color LCD display. An

external interface board can be connected to the CLCD connector to drive different size

displays.

The CLCD signals from the ARM926EJ-S PXP Development Chip are converted on the

PB926EJ-S to a VGA signal. The resolution of the VGA signal is configurable. See

Appendix C CLCD Display and Adaptor Board.

There is also a two row by sixteen character display mounted on the PB926EJ-S. This

display can be used for debugging or as the output from applications.

1.2.5 RealView Logic Tile expansion

The ARM RealView Logic Tiles, such as the LT-XC2V6000, enable the development

of AMBA AHB and APB peripherals, or custom logic, for use with ARM cores. You

can place standard or custom peripherals in the FPGA on the RealView Logic Tile.

Three AHB buses, the static memory interface, and the DMA and interrupt signals are

brought out to the RealView Logic Tile connectors. See AppendixF RealView Logic

Tile.
