Overview: PMPs & PNDs

As the market for Personal Media Players (PMPs) & Portable Navigation Devices (PNDs) has grown, they have evolved from very basic navigation and MP3 playback functionality to today's products that adopt the latest and greatest features of the consumer electronics market, including multimedia and wireless functionality.   With adoption of multimedia-rich content - particularly, video and Mobile TV - as well as different wireless technologies, OEM's are facing unique challenges in storage, feature integration, battery life and technology convergence. At an architectural level, the multimedia trend results in more and more peripherals connected to application processors. Unfortunately, application processors have a predefined set of interfaces and typically cannot be modified or updated as fast as the market requirements change. Usage of PMP and PND's for viewing movies and the Internet has led to challenges in battery life of the device.

To solve these challenges, QuickLogic has developed a broad variety of host controllers around the most common storage, networking, video and other high speed peripheral interface technologies used in PMPs. These include VEE™ technology, DPO, USB 2.0 OTG with PHY, SD/SDIO/MMC, IDE, NAND/Managed NAND & High Speed UARTs.

Challenges & Solutions: PMPs & PNDs

Increased storage needs due to high digital content, particularly video and Mobile TV.

QuickLogic supports a broad spectrum of storage choices including CE-ATA, IDE, SD/SDHC/MMC cards and Managed NAND with booting capability

Demand for multiple high speed wireless interfaces for high speed download of digital content, email and web browsing, and better user experience with services provided by companies such as exchange of songs and video.

QuickLogic provides both Hi-Speed USB 2.0, SDIO 2.0 and MPEG-TS for high speed data interface for wired and wireless connectivity. QuickLogic's technology allows high speed download of digital content

Poor image quality in varying lighting conditions, with compensation by increasing backlight or display power being offset by lowering battery life.

VEE™ and DPO technologies improve video quality and save battery life by lowering backlight or display power requirements when watching video and Mobile TV
