Embedded Pentium® Processor-Based POS Terminal Sample Design

1.0Introduction

This application note provides a sample point-of-sale (POS) terminal design using the Pentium® processor and provides recommendations to enable shorter design cycles. Also described are the various peripherals commonly used in POS terminals and their interface to a Pentium processor platform.

The tested operating systems are: QNX*, DOS, BeOS*, Windows 95*, Windows 98*, Windows NT*, Windows 3.1*, and Windows CE*. Since Windows CE is a relatively new operating system, drivers have been tested and configuration information for pertinent drivers are provided.

Caution: The design has not been implemented in hardware. This document is for reference only. Customers are responsible for validating designs created using the information in this document.

1.1Key Terms

PIIX4E refers to the Intel 82371EB PCI ISA IDE Xcelerator.

POS Terminal refers to point-of-sale terminal.

Design Features are items that allow the designer to fully use the capabilities of the embedded Pentium®processor with MMX™ technology and the Intel®440TX AGPset, and the Pentium®II processor with the Intel®430TX PCIset.

Design Notes are items that should be considered but may not apply to your design.
