Reference design aids gigbit Fibre Channel
QuickLogic has released an advanced reference design kit for Fibre Channel and other high-speed serial applications.
The SDIO reference design provides a complete bridging/controlling solution for interfacing Intel PXA27x embedded processors with SDIO peripherals and/or SD memory.
The inherent benefits of Eclipse II based solutions include a small footprint, ultra low power consumption, and proven high performance.
These attributes are critical for products such as portable global positioning systems, smart phones, portable media players, and portable industrial systems.

System configures programmable IP for comms
QuickPack from QuickLogic is a novel "point and click" system for implementing complete key interface blocks within complex communications systems designs.
"Our Eclipse II family of low-power FPGAs, coupled with our vast experience delivering both silicon and software for portable applications based on the Intel PXA27x processor family, provide an optimal solution for SDIO-enabled products", said Owen Bateman, Sales Director of QuickLogic Europe.
"Support for low-cost, low-power SDIO interfaces is just one more way that QuickLogic enables designers to accelerate their product development in the consumer electronics arena".
QuickLogic's SDIO intellectual property, embedded in the reference design, can be operated at a clock frequency of up to 52MHz, far exceeding the SDIO specification of 25MHz.
The programmability of the SDIO-enabled reference design allows designers to incorporate their unique logic requirements and tune for power or performance depending on product specifications.
QuickLogic has demonstrated that its new SDIO reference design can deliver significant improvements in the read/write performance of SD memory cards.
Using the company's Mobile Applications Board (MAB), the gains achievable were up to three times the performance versus the PXA27x processor's native mode at the same frequency, and up to five times the performance at higher frequencies.
The SDIO reference design can be combined with further IP to support designs that implement multiple interfaces to the Intel PXA27x processor, allowing designers to add peripheral functions such as 802.11g (Wi-Fi) and USB using a single FPGA device.
The SDIO IP and reference design provides designers with an easy-to-implement and proven SDIO bridging/controlling solution.
The reference design includes a QuickLogic MAB, a QuickLogic QL8325 Eclipse II microwatt FPGA, and a Microsoft Windows CE driver compatible with the Intel PXA27x processor Mainstone II DVK.
The reference design has been hardware and software proven with a Kingston 1Gbyte SD memory card, and SanDisk 64Mbyte SD memory card.
The Eclipse II FPGA family is shipping in volume, and devices with embedded SDIO IP are available for less than $5 in volume quantities.
The Mobile Application Board is also in production and costs $999.
