IP supports High-Speed USB host controllers.(leading edge)(ARC International USB-HS SPH and ARC USB-HS MPH)(Brief Article)

EDN, December, 2003 by Cravotta, Robert

ARC HAS ANNOUNCED two USB-host-controller IP (intellectual-property) offerings, the USB-HS SPH (single-port-host) and the USB-HS MPH (multiport-host) cores. The SPH core's latency-based architecture sports the lowest gate count for a single-port, high-speed host controller and supports USB low-, full-, and high-speed (to 480-Mbps) data bandwidths. The core includes a functional subset of the HS-OTG (On the Go) IP core, is EHCI (Enhanced Host Controller Interface)-compatible, and supports UTMI (USB 2.0 Transceiver Macrocell Interface) and ULPI (Unit Level Prototype Implementation) PHYs (physical-layer interfaces). The USB host-specific controllers support programmable features, such as adaptive tuning, programmable fill level, and enhanced streaming, under software...
