Abstract: High speed USB hub with full speed to high speed transaction translator. A USB hub may include an upstream port for coupling to a host and one or more downstream ports for coupling to downstream devices. The downstream devices may operate at USB high speed. The USB hub may support hosts which operate at speeds less than high speed (e.g., full speed). Accordingly, when a host operates at a lower speed, a transaction translator may convert the communications from the host from the lower speed to the high speed. Accordingly, the downstream device may still operate at high speed even when the host operates at a lower speed.

Abstract: Hub apparatus that supports multiple high speed devices and a super speed device. The hub apparatus may include at least one upstream port for coupling to a host device and at least one downstream port for coupling to at least one downstream device. The hub apparatus may further include an embedded device as well as an internal hub coupled to the upstream port, the embedded device, and the at least one downstream port. The internal hub may be configured to provide a connection between the host device and the embedded device at a first speed (e.g., USB high speed). However, when supported by the host device, the embedded device may communicate with the host device at a higher speed than the first speed (e.g., USB super speed), e.g., without using the internal hub.

Abstract: A system to select a first and second test access port controller in response to a mode of operation.

Abstract: A system to perform real time temporal correlation on pulsed and periodic signals. Application is to systems which perform PRI analysis of signals and provide signal gain as part of the correlation process. Correlation is performed in two stages, the first conditioning the signals for correlation using the zero mean, PW matched filter and the second performing temporal correlation using the difference minimization PRI correlator. The primary purpose of the filter is to minimize any DC signals before they reach the correlator. If DC signals reach the correlator, they correlate up at every PRI setting and on every temporal point, resulting in false detections and can block actual signals from detection. The filter also provides some gain for signals with pulse widths greater than one temporal cell. After conditioning with the filter, the data is correlated using a difference minimization correlator.
