Flash memory is a type of electrically erasable programmable read-only memory (eeprom). Because flash memories are nonvolatile and relatively dense, they are now used to store files and other persistent objects in handheld computers, mobile phones, digital cameras, portable music players, and many other computer systems in which magnetic disks are inappropriate. Flash, like earlier eeprom devices, suffers from two limitations. First, bits can only be cleared by erasing a large block of memory. Second, each block can only sustain a limited number of erasures, after which it can no longer reliably store data. Due to these limitations, sophisticated data structures and algorithms are required to effectively use flash memories. These algorithms and data structures support efficient not-in-place updates of data, reduce the number of erasures, and level the wear of the blocks in the device. This survey presents these algorithms and data structures, many of which have only been described in patents until now.

Although leading-edge software-development practice has advanced rapidly in 14 recent years, common practice hasn’t. Many programs are still buggy, late, and 15 over budget, and many fail to satisfy the needs of their users. Researchers in both 16 the software industry and academic settings have discovered effective practices 17 that eliminate most of the programming problems that were prevalent in the 18 nineties. Because these practices aren’t often reported outside the pages of highly 19 specialized technical journals, however, most programming organizations aren’t 20 yet using them in the nineties. Studies have found that it typically takes 5 to 15 21 years or more for a research development to make its way into commercial 22 practice (Raghavan and Chand 1989, Rogers 1995, Parnas 1999). This handbook 23 shortcuts the process, making key discoveries available to the average 24 programmer now.

The product described in this datasheet is subject to continuous developments and improvements. All particulars of the product and its use contained in this datasheet are given by ARM in good faith. However, all warranties implied or expressed, including but not limited to implied warranties or merchantability, or fitness for purpose, are excluded. .

Increasingly, embedded systems developers and system-on-chip designers select specific microprocessor cores and a family of tools, libraries, and off-the-shelf components to quickly develop new microprocessor-based products. A major player in this industry is ARM. Over the last 10 years, the ARM architecture has become the most pervasive 32-bit architecture in the world, with more than 2 billion ARM-based processors shipped at the time of this writing. ARM processors are embedded in products ranging from cell/mobile phones to automotive braking systems. A worldwide community of ARM partners and third-party vendors has developed among semiconductor and product design companies, including hardware engineers, system designers, and software developers. To date, no book has directly addressed their need to develop the system and software for an ARM-based embedded design. This text fills that gap. Our goal has been to describe the operation of theARMcore from a product developer’s perspective with a clear emphasis on software. Because we have written this book specifically for engineers who are experienced with embedded systems development but who may be unfamiliar with the ARM architecture, we have assumed no previous ARM experience. To help our readers become productive as quickly as possible, we have included a suite of ARM software examples that can be integrated into commercial products or used as templates for the quick creation of productive software. The examples are numbered so that readers can easily locate the source code on the publisher’s Web site. The examples are also valuable to people with ARM design experience who want to make the most efficient use of an ARM-based embedded system.
