Abstract: Aspects disclosed in the detailed description include inline cryptographic engine (ICE) for peripheral component interconnect express (PCIe). In this regard, in one aspect, an ICE is provided in a PCIe root complex (RC) in a host system. The PCIe RC is configured to receive at least one transport layer packet (TLP), which includes a TLP prefix, from a storage device. In a non-limiting example, the TLP prefix includes transaction-specific information that may be used by the ICE to provide data encryption and decryption. By providing the ICE in the PCIe RC and receiving the transaction-specific information in the TLP prefix, it is possible to encrypt and decrypt data in the PCIe RC in compliance with established standards, thus ensuring adequate protection during data exchange between the PCIe RC and the storage device.

Abstract: Exemplary embodiments are directed to broadcasting data on a USB system. The system includes a USB host and multiple broadcast-capable USB devices. Each USB device includes at least a default control endpoint for receiving control information and an isochronous sink endpoint for receiving a broadcast stream. The USB host programs a shared device address to an address register of each USB device such that all broadcast-capable USB devices programmed to that shared device address will accept the broadcast stream. One of the USB devices at the shared device address is set as a primary broadcast slave that will respond to non-isochronous transfers to the shared device address. All other USB devices with the shared device address are set to secondary slaves that ignore non-isochronous transfers to the shared device address.
