USB 2.0 On-The-Go (OTG) IP Core (FS and HS)-
Certified
A ‘Dual-Role’ USB 2.0 On-The-Go (OTG) IP Core that operates as both an USB 2.0
Peripheral or as an USB
2.0 OTG Host in a point-to-point communications with another USB device.

required
Compact and cost-effective solution for SoC
An USB OTG IP Core is ideal for
applications where the target device must act as a peripheral and as a
host, depending the situation. It provides portable devices with a
cost-effective way of conducting point-to-point communications using the
USB bus. A good example is a PDA which has to be a peripheral that can
sync with a host PC, but can also be a host when a peripheral, such as a
keyboard or a camera, is connected to it.
Architecture:
The USB 2.0 OTG IP
Core supports both High Speed and Full Speed operations. It will
automatically perform the required negotiation to determine if it's
counter part supports High Speed and fall back to Full Speed operation if
it does not. The speed negotiation is supported in device and host modes.
UTM + L2PHY Interface
The USB 2.0 OTG IP Core features an industry standard UTMI+ L2 interface. Any of-the-shelf
UTMIL+ L2 compliant PHY or PHY IP can be used with this IP Core.

MCU Interfaces
The USB 2.0 OTG IP Core features two WISHBONE interfaces, which can be easily adapted to AMBA AHB bus interface with our WISHBONE/AMBA bridge.
The Slave Interface is used to access all core internal registers. The Master Interface allows the USB 2.0 OTG IP Core
to share the system memory for buffering data. It is also used to store Transfer Descriptors when operating in Host Mode.
Buffer Memory
The USB 2.0 OTG IP Core does not need dedicated buffer memory. It's WISHONE Master Interface and
the internal DMA engine allow it to share the SoC's main memory for its buffers. Optionally we can also
provide a WISHBONE bridge to attach standard dedicated SRAM.
The Host Controller block is active when the USB OTG IP core operates in a OTG host mode.
In this mode it can control USB peripherals that are attached to it. It provides full support for
session request and host negotiation protocols.
Verification:
The USB 2.0 OTG IP Core comes with an elaborate test bench that demonstrates the
usage and programming of the USB 2.0 OTG IP Core.
Size & Speed:
Sample Synthesis results for an 0.18u process. The goal was smallest and fastest implementation.
