Preliminary

2. Designing the System

Introduction

To architect a system, you specify the design requirements and develop a suitable

design strategy to address each requirement. Design requirements include immediate

design goals of the product and features to keep your product commercially

successful in the future. You must consider desired application functionality, cost,

flexibility to add future features, time to market, and obsolescence.

Programmable logic solutions provide optimal flexibility in your architecture to add

features over time quickly and at low cost. For example, a programmable logic

solution enables you to add features such as graphics or video display to a

commercial implementation of the digital picture viewer quickly and cheaply.

Programmable logic solutions allow you to integrate all the parts of the design on a

single low-cost, low-power programmable logic device. They support short time to

market, and insulate your design from part obsolescence — the potential lack of

future support for specific microprocessors, LCD panels, LCD controllers, and flash

memory devices, for example — by providing the ability to migrate your design to

another device without extensive modification.

Therefore, this tutorial implements the digital picture viewer on a programmable

logic platform using Altera’s SOPC Builder.

Product design goals originate in customer requirements and become inputs to

system definition. System definition is the first step in the design process.

The following sections describe the Altera design flow for an embedded system, the

design requirements for the digital picture viewer design you implement in this

tutorial, the design strategies that dictate the decisions about the hardware

components in the implemented design, and the basic system description for the

digital picture viewer. By explaining the design flow, design requirements, and design

strategy in this chapter, this chapter teaches you the system architecture of the digital

picture viewer.
