The USB 3.0 Host controller is a highly configurable core and implements the USB 3.0 Host functionality that can be interfaced with third party USB 3.0 PHY’s. USB3.0 Host controller core is part of USB3.0 family of cores named “Pravega” containing Host and device controller. The core leverages GDA’s design expertise from its high speed interconnect family of IP’s including PCI Express, Serial RapidIO and Hypertransport.
The Pravega Host Controller core is architected with a high performance DMA engine in the xHCI Interface for maximizing performance.
The Pravega Host Controller core supports all mandatory and optional features of the xHCI power management interface. The design is carefully partitioned to support standard power management schemes. Optionally, it can be configured to manage power mode transitions of the controller and the USB 3.0 PHY for aggressive power savings required for mobile and handheld devices.
The controller has a very simple application interface which can be easily adapted to standard on-chip-bus interfaces such as AXI, AHB, OCP etc. Optionally, it can be interfaced to standard PCIe core with optional virtualization support, for standard host adaptor implementations.
The controller's simple, configurable and layered architecture is independent of application logic, PHY designs, implementation tools and, most importantly, the target technology. GDA solution allows the licensees to easily migrate among FPGA, Gate array and Standard cell technologies optimally. Its flexible backend interface makes it easy to be integrated into wide range of applications.
