USB 2.0 Super Speed host Controller IP



USB 2.0 Host controller is a highly configurable core and implements the USB 2.0 Host functionality that can be interfaced with third party USB 2.0 PHY’s. USB2.0 Host controller core is part of USB3.0 family of cores.
Host Controller core is architected with an high performance DMA engine based on xHCI specification. The core can be configured to support full-fledged USB 2.0 host controller based higher performance xHCI specification 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 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.
The controller’s simple, configurable and modular architecture is independent of application logic, PHY designs, implementation tools and, most importantly, the target technology.
