QuickLogic has announced native DVD ROM support for its IDE companion device. Based on QuickLogic's ultra-low power programmable technology, the IDE companion device provides control and interface capability between embedded processors and both IDE-based Hard Disk Drives (HDDs) and DVD ROM drives. Additionally, the IDE companion device now supports dual IDE/ATA-based devices with one master and one slave that can simultaneously interface to one DVD ROM and one HDD.
There are a multitude of popular, low power embedded processors designed into handheld, battery-powered applications; however, many do not provide a native interface to standard storage peripherals such as IDE-based HDDs or DVD ROM drives. QuickLogic, with its integrated IDE controller, provides an easy-to-implement, energy-efficient solution.
The embedded IDE controller can perform transfers to or from an IDE/ATA-based HDD and DVD-ROM in any of the PIO modes (0, 1, 2, 3 or 4). In addition, HDDs can also be accessed using Multi-Word DMA modes (0, 1, or 2). This IDE companion device has integrated bi-directional sector buffers, which directly contributes to a demonstrated performance of greater than 13MBytes/s data transfers. The IDE/ATA timing and registers are completely handled by the QuickLogic device, further reducing the processor's bus utilization and enabling more energy-efficient operation.
Pricing and availability
The IDE and DVD-ROM controller and Windows CE software drivers are available now with unit pricing starting at $5. More information on this solution can be found at www.quicklogic.com/hdd. The Mobile Application Board that supports this IDE companion device is also available now, and is currently priced at $999. For more information on the MAB, visit www.quicklogic.com/mab.
