      'Anyone who has ever uttered the joyous words, 'I saved eight bytes!' will feel at home with this coherent, easy-to-use set of patterns for limited memory systems. As the computing world moves toward hand-held and specialized tiny computing devices, these patterns will continue to show their worth. This book should be on the shelf of every person who writes software for small systems.'

- Neil Harrison, Avaya Inc.

  'Many of us have been waiting for someone to tackle the hard problems of resource shortages. In the growing collection of patterns, this book will provide some guidelines for these problems in a well-written, thoroughly enjoyable style. The authors share their real-world experience in the best patterns tradition--all the examples provide ample opportunity to see the solutions at work. This is a 'must have!'

- Linda Rising

  'The 1980s and 1990s can be described, harshly but accurately, as decades when software developers were increasingly careless about how much memory their software consumed. In 'Small Memory Software', Weir and Noble give a timely wake-up call, pointing out some unexpected merits of more thoughtful usage of memory - and giving clear practical advice that should help reverse what has been a most unfortunate historical trend.'

- David Wood, Executive Vice President, Symbian

      The market for PDA software is huge and growing. Within five years, a significant proportion of the world population will use an smart, Internet-ready mobile phone. A PC in every home? Maybe, but just as likely is a PDA in every pocket! This book offers you state-of-the-art programming solutions for small memory devices. You will learn the best, most successful design techniques for object-oriented programming in constrained memory.

  If you are a developer, team leader, or manager building applications for limited-memory systems, you will find everything you need to design and implement effective software with success.

   27 patterns, fully illustrated with implementation notes for reference plus example code in C++ or Java

Patterns organized into five major techniques: small data structures, memory allocation, compression, secondary storage, and small architecture

Easy-to-use layout, with a quick-reference pattern index on the inside covers

Tips on efficient memory allocation, dealing with memory exhaustion, using ROM instead of RAM, avoiding memory leaks, and automatically recycling unused memory

An accompanying web-site, www.smallmemory.com, containing detailed implementations of all the substantial examples in the book, which can be used as templates for your own implementations


  Author Bio

  James Noble is New Zealand's leading expert on Design Patterns for object-oriented software. James worked on object-oriented design at the Microsoft Research Institute at Macquarie University, establishing the first patterns group in the Southern Hemisphere. He currently lectures at the Victoria University of Wellington, New Zealand. Charles Weir is an independent consultant in object-oriented software architecture. He was initial architect for the EPOC web browser for the Psion series 5, and the Symbian technical lead for two smart mobile phones to be launched later this year. Charles specializes in transferring practical skills to developers, providing mentoring and design assistance to teams in the fields of telecommunications, information systems, and banking
