Certified USB 5G & 10G Dual Mode Controller
The USB 3.0 Dual Mode controller is a highly configurable core and implements the USB 3.0 Host functionality or USB3 Device functionality selectable via a register or an external pin. The host/device core can be interfaced with third party USB 3.0 PHY’s. USB3.0 Dual mode controller core is part of USB3.0 family of cores named “Pravega”.
The Pravega dual mode controller supports Host functionality using high performance DMA engine based on xHCI specification exposing either an AHB or AXI interface. The host mode core can be configured to support full fledged xHCI implementations for use in standard PCIe-USB bus adaptors/chip sets or be configured with a subset of features for embedded applications requiring limited host functionality. The pravega dual mode controller supports Device functionality which operates in a cut through mode exposing a native packet interface or exposes either an AHB or AXI interface and including a high performance proprietary DMA engine.
The Pravega Dual Mode Controller core is carefully partitioned to support standard power management schemes which include extensive clock gating and multiple power wells for aggressive power savings required for mobile and handheld applications.
The controller has a very simple application interface which can be easily adapted to standard on-chip-bus interfaces such as AXI, AHB, OCP as well as other standard off-chip interconnects making it easy to be integrated in a wide range of applications.
