Arasan Chip Systems Inc., a provider of IP products for the bus interface standards, has announced the availability of what it claims is the world's first SDIO host core compliant with the ver.2 draft spec from the SD Association and supporting the advanced DMA function. Support for advanced DMA reduces protocol overhead and improves throughput. The IP has already been delivered as the standard release to recent customers and as an upgrade to existing customers.

Private demonstrations showcasing Arasan's latest technology were held at the Las Vegas Hilton during the CES show. The demonstration platform consists of Arasan's SD/MMC4/CE-ATA Host board plugged into an X86 PC running Red Hat Linux and Microsoft Win CE 5.0. Arasan's SDIO Linux Stack was used with Red Hat and Arasan modified Microsoft Stack on CE 5.0. Various SD memory cards and Arasan AC21C00 ASIC based SDIO cards were used during the demonstration.

Prakash Kamath, VP of Engineering who was at hand during the demonstrations stated, "Major software vendors and semiconductor companies are already using Arasan's Ver 2.00 platform for interoperability testing and product development. Our many licensees have been impressed with Arasan's continued improvements to the existing product line allowing them to stay ahead of the competition."
